ABSTRACT:
A rotatable and axially movable detent disc is formed with a periphery having a triangular cross section. The sides of the triangular cross section are formed with circumferentially spaced triangular detent grooves. A detent member is resiliently urged against the periphery of the disc for yieldable detent disc holding engagement in the detent grooves. The grooves provide a plurality of rotational detent positions corresponding to the number of grooves and the apex of the triangular cross section of the periphery of the disc provides two axial detent positions with the apex on either side of the detent member respectively.
