Abstract: A voltage control device in one aspect of the present disclosure includes an appliance connector, a voltage output circuit, a manual switch, and a controller. The voltage output circuit outputs an operating voltage based on a direct voltage received from a direct-current power source. In response to a first electric appliance being connected to the appliance connector, the controller controls the voltage output circuit so as to fix the operating voltage. In response to a second electric appliance being connected to the appliance connector, the controller controls the voltage output circuit so as to vary the operating voltage in accordance with a manual operation applied to the manual switch.

Abstract: A system may include: a motor unit comprising an output member and a fixing member; a first working unit configured to be selectively fixed to the fixing member; and a second working unit configured to be selectively fixed to the fixing member. In a case where the fixing member is fixed to the first working unit, the fixing member of the motor unit may be oriented in a first direction relative to a reference plane when the first working unit and the motor unit are in a first working posture relative to the reference plane. In a case where the fixing member is fixed to the second working unit, the fixing member of the motor unit may be oriented in a second direction relative to the reference plane when the second working unit and the motor unit are in a second working posture relative to the reference plane.

Abstract: A power-supply system includes an electric work machine, a power-supply apparatus, and an adapter. The power-supply apparatus outputs a power-supply voltage. The adapter is coupled between the power-supply apparatus and the electric work machine and relays the power-supply voltage output from the power-supply apparatus to the electric work machine. A work machine communicator of the electric work machine performs, with the adapter, a digital communication in which a voltage level of an electrical signal is sequentially switched between a high level and a low level over time according to communication content. A power-supply communicator of the power-supply apparatus performs the digital communication with the adapter. An adapter communicator of the adapter performs the digital communication with the electric work machine and performs the digital communication with the power-supply apparatus.

Abstract: A light unit is less likely to have lower light emission performance upon receiving a shock. An electric work machine includes a motor, a housing including a motor compartment accommodating the motor and a grip protruding downward from the motor compartment, an output unit located frontward from the motor and operable with a rotational force from the motor, a substrate extending above, on a left, and on a right of the output unit, and a plurality of light emitters mounted on a front surface of the substrate at intervals in a circumferential direction of the output unit. A light emitter of the plurality of light emitters nearest an apex of the substrate immediately above the output unit is at a position shifted circumferentially by a predetermined angle from the apex.

Abstract: A portable cutting machine includes an electric motor, a base having a lower surface coming in contact with a workpiece, a cutting machine body coupled to an upper surface of the base and accommodating the electric motor, a handle on a rear portion of the cutting machine body and at least partially rearward from a rear end of the base, a blade on a left or a right of the handle and rotatable with the electric motor, and a battery attachment portion receiving a battery pack for powering the electric motor. The battery attachment portion includes an opening directed away from the blade, an attachment surface standing with respect to the base, and a rail receiver extending in the attachment surface to receive the battery pack in a detachable manner. The battery pack on the rail receiver extends laterally over a center plane of the handle.

Abstract: A core drill includes: a motor having a rotor, which is rotatable relative to a stator about a rotational axis extending in the front-rear direction; a speed-reducing mechanism, which is disposed more forward than the stator; an output shaft, at least a portion of which is disposed more forward than the speed-reducing mechanism and which, in the state in which a core bit is mounted thereon, is rotated by the rotational force of the rotor transmitted via the speed-reducing mechanism; a battery-mounting part, on which a battery pack is mounted; a motor-housing part, which houses the motor; a grip part, at least a portion of which is disposed along the extension of the rotational axis more rearward than the motor-housing part; and a controller, which controls the motor. In the front-rear direction, at least a portion of the controller is disposed between the motor and the grip part.

Abstract: A rotary hammer selectively operates in multiple modes including a first mode and a second mode. The rotary hammer includes a switch, a motor, a switch manipulation member, a locking member, and a mode detecting device. The switch manipulation member includes a body, and a protrusion that is movable between a protruding position and a retracted position. The body houses a solenoid configured to operate based on a detection result of the mode detecting device. The locking member is movable between an unlock position and a lock position where the locking member holds the switch manipulation member in an ON position by abutting the protrusion in the protruding position. The protrusion is integrated with a plunger of the solenoid. The protrusion is configured to be in the protruding position when the present mode is the first mode, and in the retracted position when the present mode is the second mode.

Abstract: A power tool reduces performance deterioration. The power tool includes a motor, an output unit, a motor compartment, and a grip. The motor includes a rotor bearing and a rotor rotatable about a rotation axis extending in a front-rear direction. The rotor includes a rotor magnet, a core to which the rotor magnet is fixed, and a shaft protruding from an end face of the core and supported by the rotor bearing. The shaft and the core together are a single member. The output unit is at least partially located frontward from the motor and rotatable by the rotor. The motor compartment accommodates at least a part of the motor. The grip protrudes downward from the motor compartment.
