ABSTRACT:
Cam surfaces are formed in the inner periphery of a cylindrical body of a shell. Rollers are moved against action of springs in the lock direction in which the space between the cam surfaces and a drive shaft becomes narrower, whereby the shell and the drive shaft are locked to transmit power from the drive shaft to a driven shaft. After transmission of the power, the rollers are radially and outwardly pressed against the inner periphery of the cam surfaces in the unlock direction in which the space between the cam surfaces and the drive shaft is wider, by co-action of a centrifugal force and a component force, thus a "dancing phenomenon" is prevented. A flange of the shell is spline-engaged with the driven shaft, an annular abutment plate in the inner periphery of the flange is held between a step of the driven shaft by an axially movable sleeve fitted around the small diameter portion of the driven shaft and the drive shaft without an axially loose condition by a fixing member.
