<p>PURPOSE:To attain the miniaturization and light weight of the titled device by providing function changing over to which of a mode lever and a loading member a motor torque is to be delivered and a function locking the mode lever and the loading member to one changeover member. CONSTITUTION:In applying a large drive load to the loading member 14 by the changeover member 14, the transmission destination of the torque of a motor 1 is selected to the mode lever 17 and the loading member 14 is locked by the large drive load. When the changeover member increased the drive load of the mode lever 17, the transmission destination of the torque of the motor 1 is selected to the loading member 14 and the mode lever 17 is locked by the large drive load. That is, the changeover ember has plural functions of locking and torque transmission changeover. Thus, remarkable decrease of the number of components is realized and the size of the device is reduced and the weight of the device is made light.</p> |
