Abstract
An anti-self rotation mechanism for preventing self-rotation of the eccentric shaft includes a long orbiting key formed at an end of the eccentric shaft, a ring formed of a long hole through which the orbiting key slides, ring keys that extend toward both outer sides in the direction orthogonal to the longitudinal direction of the hole, and two key grooves formed in the casing, through which the ring keys slide.
