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 work tool includes an elongate outer housing, an elongate inner housing, a motor, a spindle, and a transmitting mechanism. The inner housing includes a first end part, a second end part, an extending part and an elastic connection part. The motor, the spindle and the transmitting mechanism are disposed in the first end part of the inner housing. The first end part is connected to the outer housing via a first elastic member. The second end part includes a power-source-related device configured to enable power supply from a power source to the motor. The elastic connection part includes second elastic members connecting the extending part and the second end part. The second elastic members are spaced apart from each other in a circumferential direction around the longitudinal direction.

Abstract: An electric oscillating tool has an electric motor having an output shaft, an eccentric shaft that is connected to one end region of the output shaft, and a weight that is connected to the other end region of the output shaft. A blade as a tool accessory is driven to reciprocally rotate around a spindle by reciprocating motion of the eccentric shaft in a transverse direction of the electric oscillating tool. The weight is driven to cancel out the inertial force of the eccentric shaft, so that the output shaft is stably rotated.

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, a switch, a housing, a switching member and a holding member. The housing is a hollow body formed by a first housing part and a second housing part connected with the first housing part. The first housing part has a through hole. The switching member is connected to the switch and includes an operation part exposed outside through the through hole so as to be movable in a specified direction in response to a user's manual operation. The switching member is configured to turn the switch on and off by linearly moving in the specified direction. The holding member is supported by at least one of the first housing part and the second housing part within the housing and configured to hold the switching member between the holding member and the first housing part so as to be linearly movable in the specified direction.

Abstract: A work tool includes a spindle and a clamp shaft. The spindle is supported to be rotatable around a driving axis defining an up-down direction of the work tool. The clamp shaft includes a shaft part and a fixing part. The shaft part extends coaxially with the spindle. The fixing part is coupled to the shaft part on a lower side of the spindle. The clamp shaft is supported to be movable in the up-down direction relative to the spindle. The clamp shaft is configured to be biased upward and to fix the tool accessory to a lower end portion of the spindle by the fixing par. The fixing part is configured to be removable from the shaft part and to be integrally coupled to the shaft part only by moving upward relative to the shaft part.
