Abstract

A rotary member rotatably supports a plurality of balls, disks or rolls which are pressed on a stator by a pressure member. When the stator generates progressive wave, the balls, disks or rolls are rolled on the stator and the pressure member by the progressive waves. Since the balls, disks or rolls are rolled on the stator and the pressure member, the wear of the stator, the pressure member and the balls, disks or rolls is decreased. Lubricative oil may be applied to the circumference of the balls, disks or rolls of the rotary member.
