    • A cam mechanism includes an input member and an output member (18) and a second cam groove (20) is provided on a surface of the output member (18). The cam mechanism is configured to sandwich a rolling element accommodated in the second cam groove (20). The second cam groove (20) has; a first region (A) provided such that an inclination angle, relative to a rotary surface, of a bottom face of the second cam groove (20) on which the rolling element makes rolling contact at the time when a phase difference is not more than a predetermined amount, is increased; and a second region (B) provided such that the inclination angle, relative to the rotary surface, of that bottom face of the second cam groove (20) with which the rolling element (17) makes rolling contact at the time when the phase difference is more than the predetermined amount, is smaller than a largest inclination angle in the first region (A).
    • 凸轮机构包括输入构件和输出构件(18),并且在输出构件(18)的表面上设置有第二凸轮槽(20)。 凸轮机构构造成夹持容纳在第二凸轮槽(20)中的滚动元件。 第二凸轮槽(20)具有: 第一区域(A),其设置为相位差不大于所述第二凸轮槽(20)的底面的滚动体滚动接触的倾斜角度 增加预定量; 以及第二区域(B),其设置成使得相对于旋转表面的第二凸轮槽(20)的底面的倾斜角度与滚动元件(17)在相位差 大于预定量,小于第一区域(A)中的最大倾斜角度。
