Claims

[Scope of utility model registration request]

A movable member to be driven so that its central axis describes a circular orbit with a radius Ror, a drive mechanism coupled to the movable member to give the movable member the circular orbital motion, and a circular orbital motion of the movable member. and a mechanism for preventing rotation of the movable member during a period of time, the rotation preventing mechanism comprising: a first ring fixed to a fixed member fixing the drive mechanism; and a second ring fixed to the movable member with a slight gap therebetween, and each of these rings has a plurality of axially perforated holes at corresponding positions in the circumferential direction. The bearing has a circular pocket so that the element is held between the pocket of the first ring and the pocket of the second ring during the circular orbit movement of the movable member, and both rings include a circular pocket. A rotation prevention mechanism for a rotating piston type fluid device, characterized in that a pin hole is bored through which a pin for fixing the ring is inserted, and a pin hole is provided in the pin hole provided in at least one of the rings.
