Abstract
A rotation transmission device which has a driving member, a driven member, engaging elements mounted between them, and a device for mechanically changing over the transmission and cut-off of turning effort and which restricts the operation of the changeover device as necessary. Between the outer ring as a driven member and the inner member as a driving member, a retainer holding the sprags spaced from one another is mounted. In the inner member are housed a solenoid and a coupling member engaging the outer ring. The solenoid is actuated by contact of a brush against a slip ring, so that the coupling member couples the outer ring with the inner member, thus causing the sprags to be inoperative.
