PURPOSE:To enable power to be selectively transmitted to any operation shaft by means of a single motor by installing a motor to the output shaft of which solenoid clutches are connected for selfrotation and power transmission respectively, on a rotor cooperating with an arc gear located below. CONSTITUTION:Among a plurality of operation shafts 30 pivoted on the curved plate 11 of a sectorial base frame 10, when the destination of transmitted driving power of a motor 40 is switched from a certain operation shaft 30 to another operation shaft 30, a power transmitting clutch 60 shall be put in OFF state to release its engagement with a clutch plate 31, a solenoid clutch 50 for moving shall be put in ON state, and the motor 40 is driven to force a gear 51 to roll on an arc-shaped rack gear 15 by means of an output shaft 41 so that a rotor 20 can make turning movement around a support shaft 14. Then, when the rotor is positioned while facing a desired operation shaft 30, the motor 40 is stopped to place the solenoid clutch 50 for moving in OFF state and to place the power transmitting solenoid clutch 60 in ON state so that the output shaft 41 can be connected to the corresponding operation shaft 30 in a state capable for transmitting power. Thus, a plurality of operation shall be made feasible by means of a single motor so that a space for installation may be reduced.
