Abstract
A selectable clutch includes a selector that performs ON/OFF operations of a first clutch mechanism. The first clutch mechanism includes a power-transmitting element that transmits or cuts off power between an input-side rotating element and an output-side rotating element in both rotational directions. The selector is coupled to an input shaft element, and coupled to the input-side rotating element by an engaging mechanism having a circumferential play permitting a relative rotation with respect to the input-side rotating element within a predetermined rotational angle range. A disconnect mechanism is configured such that the output-side rotating element is coupled to an auxiliary driving wheel axle, and the selector is coupled to the motor shaft of an auxiliary driving motor.
