摘要： A grinder as a power tool has a torque limiter. The torque limiter includes a second bevel gear; a spindle; a flange to which the rotation of the second bevel gear is transmitted, and a plurality of balls which are disposed between the second bevel gear and the flange. The ball is positioned at a first region and the second bevel gear, the ball and the flange rotate integrally thereby the rotation is transmitted to the flange. In a state that a torque exerted on the spindle exceeding the predetermined threshold, a relative rotation between the second bevel gear and the flange is occurred and the ball moves from the first region to the second region while rolling by means of the relative rotation. Therefore, the transmission of the rotation from the second bevel gear to the flange is regulated, and the torque exerted on the spindle is regulated.

摘要： A power tool having a gear speed reducing mechanism which is free of backlash and a planetary gear speed reducing mechanism. The planetary gear speed reducing mechanism has a driving-side member that is rotationally driven by a prime mover, a driven-side member which is rotatably and coaxially disposed with the driving-side member and to which a tool bit is coupled, and an intervening member which is disposed between the driving-side member and the driven-side member. The intervening member 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 when the driving-side member is rotationally driven, so that torque of the driving-side member is transmitted to the driven-side member at reduced speed.

摘要： The power tool has a power transmitting mechanism. When a tool bit is not pressed against a workpiece, the power transmitting mechanism is held in a power transmission interrupted state, and when the tool bit is pressed against the workpiece, the power transmitting mechanism is held in a power transmission state in which the tool bit moves together with the driven-side member in an axial direction of the tool bit so that the driving-side member receives the torque from the driven-side member and the tool bit is driven. Tapered portions are provided between the driving-side member and the driven-side member and inclined with respect to the axial direction of the tool bit. When the driven-side member moves in the axial direction of the tool bit, frictional force is caused on the tapered portions and the torque of the driving-side member is transmitted to the driven-side member by the frictional force.

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.
