Object: In a scroll type fluid machine in which a stationary scroll 1 and a swivel scroll 2 engaged therewith are contained within a hermetic housing 4, a plurality of legs 15 provided on the outer circumferential edge of an end plate 11 of the stationary scroll 1 are fixed by bolts 64 to a frame 5 supporting a rotating shaft 3 via a bearing 52, a rotation prevention mechanism 6 is interposed between the frame 5 and the swivel scroll 2, and the swivel scroll 2 is connected to the rotating shaft 3 so as to make revolutional swivel motions, the diameter of the end plate 11 of the stationary scroll 1 is shortened and thereby the hermetic housing 4 is made smaller. Solving means: A cut out recess portion 25 is provided at each position, corresponding to the plurality of legs 15, of the outer circumferential portion of a circular end plate 21 of the swivel scroll 2. <IMAGE> |
