combination of a drive side cam and a driven cam to realize a structure that can easily determine whether or not appropriate. Of the outer peripheral surface of the driven side cam 30a, to form a diametrically opposed become two positions driven side groove 47 to the position, while the recessed axially over the radially inner side. Of the outer peripheral surface of the drive side cam 29a, recessed radially inwardly over the axially first drive-side groove 45 in the portion where the circumferential direction about the phase matches the driven side groove 47 in the locked state formed by the state, it is formed in a state in which the circumferential direction about the phase is recessed a second drive groove 46 in the axial direction over radially inward in part to match the driven side groove 47 in the unlocked state.
