The driven gear is supported in such a way as movable in the axial direction of the driven shaft, and a rotation transmitting means is disposed between the driven gear and the driven shaft. A positioning means for limiting the amount of movement of the driven gear in the axial direction is disposed in the driven gear or in the driven shaft, and an elastic member is disposed in the axial direction of the driven gear. <P>COPYRIGHT: (C)2012,JPO&INPIT |
