Abstract: A power tool includes a spindle, a motor, an inner housing and an outer housing elastically connected to the inner housing. The inner housing is formed by a first inner housing portion formed of metal connected to a second inner housing portion formed of synthetic polymer. The first inner housing portion includes a housing part disposed in a front part of the outer housing, and a first extending part extending rearward from the housing part and disposed in a grip part of the outer housing. The second inner housing portion includes a second extending part that has a tubular shape and at least partially surrounds the first extending part, and a rear end part connected to the second extending part and disposed in a rear part of the outer housing. The first extending part extends rearward of a center of the second extending part in the front-rear direction.

Abstract: A power tool includes a housing, a spindle, a clamp shaft, a first biasing member, an engagement member, a first holding member, a manually operable member and a push-down member. The first biasing member biases the clamp shaft upward. The first holding member holds the engagement member to be movable between a first position and a second position in the up-down direction relative to the first holding member. The manually operable member moves a first one of the engagement member and the first holding member downward in response to a manual unclamping operation. The engagement member moves from the first position to the second position to be movable in the radial direction in response to the manual unclamping operation. The first one of the engagement member and the first holding member pushes down a tool accessory via the push-down member while the first one is moving downward.

Abstract: A power tool includes a motor having an output shaft rotatable around a first axis, a spindle rotatably supported around a second axis, a transmitting mechanism configured to reciprocally rotate the spindle within a specified angle range around the second axis, an elongate support body supporting the motor, the spindle and the transmitting mechanism, an elongate housing that houses the support body, and a first elastic member interposed between the housing and a first end part of the support body and connecting the housing and the support body so as to be movable relative to each other. The spindle is supported in the first end part such that the second axis crosses the direction of a longitudinal axis of the support body. The support body has a weight provided to increase an inertia moment of the support body around the second axis.

Abstract: A power tool includes a housing (10), a spindle (4) supported in the housing to be pivotable or rotatable about a driving axis, a clamping shaft (60) that is selectively movable in the up-down direction relative to the spindle, a biasing member (70), a release member (71) and an actuating member (50). The release member is selectively movable in the up-down direction relative to the spindle and is configured to selectively interrupt transmission of upward biasing force from the biasing member to the clamping shaft. The release member is also configured to be locked to the spindle in a locked position while transmission of the biasing force is being interrupted. The actuating member is movable upward in the up-down direction relative to the spindle in response to being pressed upward by a clamping part (64) or by a tool accessory (91) to thereby unlock the release member from the spindle.
