Zusammenfassung:	PROBLEM TO BE SOLVED: To improve lubricity of an Oldham mechanism to prevent rotation of a movable scroll, in a scroll-type compressor.SOLUTION: In a movable scroll 20 constituting a scroll-type compressor 10, a pair of key grooves 82 are formed on a back face 66a of a movable-side base portion 66 so that a key portion 86 of an Oldham ring 84 is engaged therewith. The key grooves 82 have a bottom face portion 90 and a pair of side wall portions 92a, 92b as processed faces formed by processing the movable-side base portion 66 formed by, for example, forging and molding, and a lubricant retaining groove 94 to which the processing is not executed, and which is recessed to the bottom face portion 90. The key portion 86 inserted to the key grooves 82 is supported along the side wall portions 92a, 92b, and properly lubricated by a lubricant retained in the lubricant retaining groove 94.
