Abstract
A torque cam mechanism comprises first and second cam members disposed relatively rotatably around a common axis and cam balls adapted to fit in first and second cam grooves formed, respectively, in confronting surfaces of the first and second cam members. The depth of the first cam grooves is made larger than the radius of the cam balls, whereas the depth of the second cam grooves is made smaller than the radius of the cam balls, whereby even though a centrifugal force is applied to the cam balls which rotate together with the first and second cam members, the generation of thrust forces for separating the confronting surfaces of the first and second cam members can be suppressed by receiving the centrifugal force so applied to the cam balls by the first cam grooves which are deeper.
