Abstract
A scroll type fluid machine has a stationary scroll 1 and a swivel scroll 2 engaged therewith contained within a hermetic housing 4. A plurality of legs 15 are provided on the outer circumferential edge of an end plate 11 of the stationary scroll 1, and 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. 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. 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.
