Abstract

PURPOSE:To enable easy formation of a rotation-preventing slider for preventing the rotation of a scroll member during its circular motion, by forming key grooves on the side of a radial projection and on the side of the scroll member. CONSTITUTION:Two key grooves 245 are formed on a straight line in the side end face of an axial projection 243 of a disc-shaped side plate 241 of a scroll member 24. There is arranged a cylindrical rotation-preventing slider 29a which is formed with a first key 291 at a position opposed to the groove 245 and with a second key 292 at a position on the opposite face deviated from the first key 291 by 90 deg.. On the inside surface of a side wall 13 is formed a radial projection 131 which is provided with a key groove 132 at a position opposed to the second key 292. By thus forming key grooves on the side of the projection 131 and on the side of the scroll member 24, the slider 29a can be formed easily.
