摘要： A hand-held rotary tool is provided which can offer improved usability while realizing reduction of vibration of a tool body. The rotary tool has a tool body, a drive shaft disposed in the tool body, a driven shaft to which a tool bit is attached, an Oldham's coupling that transmits rotation of the drive shaft to the driven shaft, and an elastic element disposed between the driven shaft and the tool body. The driven shaft is prevented from moving in a longitudinal direction of the driven shaft relative to the tool body and allowed to move in a direction transverse to the longitudinal direction of the driven shaft relative to the tool body. During this relative movement, power transmission from the drive shaft to the driven shaft is maintained via the Oldham's coupling. The elastic element absorbs the movement of the driven shaft relative to the tool body.

摘要： An electric hammer comprising a hammer bit (313) performing hammering work on a work, a drive motor, a hammering piece (334) driven by the drive motor to apply a hammering force to the hammer bit, and a mechanism (371) for damping vibration generated during hammering. The damping performance of the electric hammer is enhanced by causing the driving amount applied to the damping mechanism (371) to vary between a first mode where the damping mechanism (371) generates vibration of the hammer bit (313) subjected to an external force from the work during the load driving time and thereby optimizes the damping and a second mode where the damping mechanism (371) generates vibration corresponding to the vibration of the hammer bit (313) not subjected to an external force from the work during the no-land driving time and optimizes damping.

摘要： It is an object of the invention to provide an effective technique for improving the durability of a torque limiter utilized in a power tool. The object is achieved by a representative power tool comprising a tool bit, a driving mechanism and a torque limiter. The torque limiter includes first and second rotating members, a ball, a pressing member and an elastic member. The second rotating member includes a power transmitting region with a groove continuously formed from a deepest groove part to a shallowest groove part to allow torque transmission and a power transmission interrupted region with a groove shallower than the shallowest groove part of the power transmitting region to interrupts the torque transmission. According to this construction, when the ball is in the power transmitting region, the pressing member contacts the first rotating member and is held in a position in which the biasing force of the elastic member is prevented from acting upon the ball.

摘要： It is an object of the present invention to provide a reciprocating power tool having a further improved power transmission mechanism for converting a rotating output of a driving motor into linear motion in the axial direction of the tool bit. According to the present invention, a representative reciprocating power tool may comprise a tool bit, a driving motor, a power transmission mechanism. The power transmission mechanism converts a rotating output of the driving motor into linear motion in the axial direction of the tool bit. The power transmission mechanism includes an internal gear, a planetary gear and a power transmission pin. The internal gear is allowed to rotate by a predetermined degree in relation to a load applied to the tool bit. As the result of rotation of the internal gear, the relative position of the power transmission pin is changed with respect to the point of engagement between the internal gear and the planetary gear. Thus, a linear stroke of the power transmission pin in the axial direction of the tool bit is changed.
