Abstract: A driving tool includes a piston, a driver, and a lift mechanism. The piston moves in a driving direction by a pressure of a gas. The driver extends from the piston and includes a plurality of engaged portions. The lift mechanism moves the driver in a direction opposite to the driving direction. The lift mechanism includes a rotation shaft, a wheel, a plurality of engaging portions, and a supporting member. The wheel rotates integrally with the rotation shaft. Each of the plurality of engaging portions may engage an engaged portion. The supporting member supports the wheel so the wheel is allowed to move between an initial position and an eccentric position in a radial direction of the rotation shaft.

Abstract: A coupling member for an electric power tool is provided. The coupling member can keep a hanging member being held, even when a holding portion of the tool for holding the hanging member breaks. A coupling member for an electric power tool is configured to hook a hanging member to an electric power tool main body and can fasten the electric power tool main body therein, when one of its parts opens or closes. Further, this coupling member can be attached to the electric power tool main body with the electric power tool main body fastened therein or removed therefrom. Further, the hanging member can be hooked to the coupling member.

Abstract: Reciprocating power tool is provided which is improved in vibration isolation of the handle. The reciprocating power tool has a tool body and a handle connected to the tool body. When an axial direction of a tool bit is defined as a longitudinal direction, the handle extends in a vertical direction crossing the longitudinal direction. Further, an upper region of the handle is connected to the tool body via an elastic member and a lower region of the handle is connected to the tool body via a support shaft that it can rotate around an axis of the support shaft in a transverse direction crossing both the longitudinal direction and the vertical direction with respect to the tool body. When the handle rotates around the support shaft with respect to the tool body, the elastic member reduces vibration which is caused in the tool body and transmitted to the handle.
