Abstract: An electric tool may include a tool main body configured to be able to mount a battery pack. The tool main body may include an electric motor, a controller for controlling the electric motor, and a centrifugal fan rotatably driven by the electric motor for producing a flow of air. The controller may be positioned such that the flow of air produced by the centrifugal fan is applied to at least a part of the controller.

Abstract: A dust collection nozzle 60 extends from the front of a fixing cover 14 parallel to a base 2 below an upper end of an electric motor 25. Heavy and large cutting dust can be immediately collected from an area relatively close to a cutting position C of a portable cutting device 1 cutting a workpiece W immediately after dust is generated due to the cutting, which can in turn improve dust collection efficiency of a dust collection device to which the dust collection nozzle 60 is attached.

Abstract: A lever device is configured such that, when first and second plates are relatively moved in a direction in which a second end part of the first plate and a fourth end part of the second plate are close to each other from a state in which the second end part and the fourth end part are separated from each other in an axial direction of a bolt, the first plate is rotated around a fulcrum positioned between a first engagement part and the second end part in the crossing direction so that the first plate is moved from an engaged position where the first engagement part and a non-circular part of the bolt or a nut are engaged to a non-engaged position where they are not engaged, and thereby removing a restriction of the relative rotation of the first plate to the non-circular part.

Abstract: A portable machining apparatus has high operability in tilting a body with respect to a base or in machining a workpiece with the tilting body. A portable machining apparatus placeable on a long gauge placed on an upper surface of a workpiece includes a base placeable on the long gauge, a body including a blade for machining the workpiece, an angular plate fixed to the base to support the body in a tiltable manner and including a protrusion, a body support located between the body and the base and including a guide engageable with the protrusion to allow sliding of the protrusion on the guide, and a spring that urges the protrusion toward the guide.

Abstract: A portable cutting machine allows a large battery pack to be attached on the rear of a handle unit without largely increasing the height of the handle unit. A portable cutting machine to which a battery pack having a connecting surface is attachable includes a base that comes in contact with a workpiece, a cutting machine body supported on an upper surface of the base and including a cutting blade protruding from a lower surface of the base to cut the workpiece, an electric motor that drives the cutting blade, and a handle unit grippable by a user, and a battery attachment portion located opposite to the cutting blade with respect to the handle unit to receive the battery pack attachable by sliding in a posture with the connecting surface facing sideward.

Abstract: A power tool may include a rotational force generating device and a rotational driven shaft coupled to a rotational drive shaft of the rotational force generating device via a transmission mechanism, so that the rotation of the rotational drive shaft is transmitted to the rotational driven shaft via the transmission mechanism. One or each of the rotational drive shaft and the rotational driven shaft is rotatably supported by at least three bearings.

Abstract: A hand-held cutting tool may include a handle and a battery pack. The handle has a rear portion with respect to a work proceeding direction along which the cutting tool is moved for performing a cutting operation. When the battery pack is mounted to the rear portion of the handle, the longitudinal direction of the battery pack extends non-parallel with the work proceeding direction.
