Abstract
A two-way clutch is provided which comprises an inner member formed with a plurality of pockets opening toward its outer peripheral surface, an outer member mounted on the inner member and formed with a plurality of pockets opening toward its inner peripheral surface, a cam ring formed with a cam surface on its inner peripheral surface, a plurality of block members received in the pockets of the inner member so as to protrude in a diametric direction, a plurality of resilient members received in the pockets of the inner member for biasing the block members radially outwardly, and a switch spring mounted to the inner member for maintaining a predetermined phase of the cam ring relative to the inner ring. With this construction, the inner and outer members can be engaged through the block members to transmit power by aligning the pockets of the inner and outer members with each other and by controlling the phase of the cam ring. Also, a rotation transmission device is provided which includes a first rotary member, a second rotary member, the above-described two-way clutch, and an electromagnetic clutch.
