摘要：
In a rotation preventing mechanism in which a ball (26) is interposed between a pair of races (24, 25) each having a rolling groove surface (24c, 25c) receiving the ball, the rolling groove surface has a bottom portion (24c3, 25c3) of a radius of curvature which is greater than each of those of an outer peripheral portion (24c1, 24c2) and an inner peripheral portion (25c2, 25c2). Each of the radii of the outer peripheral and the inner peripheral portions is approximate to and greater than the radius of the ball. The races are attached to a front housing (10b) and a movable scroll member (20) which carries out orbital motion along a predetermined orbit with respect to the front housing. The rolling groove surface has an annular shape corresponding to the predetermined orbit.
