Abstract: It is an object of the invention to provide rational structure for vibration proofing in hammering operation. A driving motor 110 and a striking mechanism 140 are provided in a first body element 101a, and a handle 109 and a battery mounting part 160 are provided in a second body element 101b. The first and second body elements 101a, 101b are moved with respect to each other via a biasing member 181 when vibration is caused by driving of the striking mechanism 140. Further, a first region 100a close to the striking mechanism 140 forms a long-distance moving region 200 in which the first and second body elements 101a, 101b move a longer distance in a longitudinal direction than in the second region 100b less close to the striking mechanism 140.

Abstract: A power tool, such as a rotary hammer or hammer drill, includes a first housing that contains a motor and a drive mechanism for linearly reciprocally driving a tool accessory, and a second housing that includes a handle, a first portion and a second portion. At least one elastic element connects the first and second housings such that the handle is biased away from the first housing. A first set of sliding contact surfaces is defined on or connected to the first housing and the first portion of the second housing. A second set of sliding contact surfaces is defined on or connected to the first housing and the second portion of the second housing. The first and second sets of sliding contact surfaces are located on opposite sides of the motor such that the rotational axis of the motor intersects the first and second sets of sliding contact surfaces.

Abstract: A power tool having a rotary hammer mechanism has a motor, a driving mechanism, a tool body that houses the motor and the driving mechanism, a handle having a grip part, and a first operation member. The driving mechanism is configured to operate by power of the motor in an action mode that is selected from a plurality of operation modes including a first mode of at least rotationally driving a tool accessory around a driving axis and a second mode of only linearly driving the tool accessory along the driving axis. The grip part extends in a direction crossing the driving axis and is configured to be held by a user. The first operation member is on the tool body and faces the grip part. The first operation member is configured to be manually operated by the user to change the action mode of the driving mechanism.

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 reciprocating tool includes a motor, a driving mechanism, a body housing, a movable part, and a vibration control mechanism. The driving mechanism includes a reciprocating member configured to reciprocate in a first direction. The movable part is connected to the body housing via a first elastic member and a second elastic member to be relatively movable in the first direction. The vibration control mechanism includes at least one weight configured to move in a direction opposite to the reciprocating member. The center of gravity of the at least one weight is offset from the driving axis in a second direction. In the second direction, the first elastic member is closer to the center of gravity than the second elastic member. A load of the first elastic member when the movable part is placed in a closer position is smaller than a load of the second elastic member.
