摘要： A screw driver (100) which comprises a motor (110) and a rotation transmission mechanism (120) is provided. The rotation transmission mechanism (120) comprises a driving gear (125), a spindle (150), a roller (141) and a retainer (130). The retainer (130) moves the roller (140) in a circumference direction of the spindle (150) and thereby a position of the roller (140) between a transmittable position and a non-transmittable position is switched.

摘要： A power tool having a gear speed reducing mechanism which is free of backlash is provided.
The power tool has a planetary gear speed reducing mechanism 131. The planetary gear speed reducing mechanism 131 has a driving-side member 135 that is rotationally driven by a prime mover 111, a driven-side member 139 which is rotatably and coaxially disposed with the driving-side member 135 and to which a tool bit 119 is coupled, and an intervening member 137 which is disposed between the driving-side member 135 and the driven-side member 139. The intervening member 137 is configured as a planetary member and at least caused to rotate by frictional force acting on its contact surface in contact with the driving-side member 135 when the driving-side member is rotationally driven, so that torque of the driving-side member 135 is transmitted to the driven-side member 139 at reduced speed.

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 corresponding to the vibration of the hammer bit (313) subjected to an external force from the work during the load diving 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-load driving time and optimizes damping.

摘要： It is, accordingly, an object of the present invention to provide an electric hammer with improved construction, while ensuring the vibration reduction performance. According to the present invention, a representative electric hammer may include a hammer bit (129), a driving motor (121), a crank mechanism (123) and a counter weight (201). The crank mechanism drives a striker (128) by converting a rotating output of the driving motor to linear motion in the axial direction of the hammer bit. The counter weight is detachably mounted to the crank mechanism and serves to reduce vibration of the striker. The hammer further comprises a counter weight driving device (203) including a counter weight driving crank (205) and a crank pin (207), wherein the counter weight driving crank (205) is rotatably supported via a bearing (206) to rotate within the horizontal plane.

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 (101) comprising a tool bit (119), a driving mechanism and a torque limiter (151). The torque limiter (151) includes first and second rotating members, a ball (155), a pressing member and an elastic member (159). 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 (155) 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 (159) is prevented from acting upon the ball.
