ルの渦巻体間の管理が困難となる問題がある。 By the way, as shown in FIG. 6, the applicant of the present application first has a disc-shaped base body B2 having a discharge hole B1 in the center,
a spiral body B protruding downward from the plane of the base body B2;
3 and the base body B on the outside of this spiral body B3
A suction passage is provided at a starting end position of the spiral body B3 in the partition wall B4 of the fixed scroll B, which is provided with an annular partition wall B4 protruding downward from the outer peripheral edge of the fixed scroll B, and at an opposing position opposite to the starting end. While opening B5,
A plurality of axial through holes are provided in the non-intake path portion of the partition wall B4, and mounting screws are inserted into each of the through holes with the end surface of the partition wall B4 facing the outer circumference of the upper surface of the housing D. A structure in which the fixed scroll B is fixed to the housing D has been proposed. (Patent Application No. 61-66694) (Problems to be Solved by the Invention) However, in the case of this fluid machine, the suction passage of the fixed scroll has a compact design, so the outer diameter of the fixed scroll is expanded. Since the inner surface portion of the partition wall is missing without any problem, the suction passage is opened at a position opposite to the partition wall in the fixed scroll, and the wall thickness of the partition wall at the suction passage opening portion is thinned. The span between the suction passage opening parts is longer than the span between the non-suction passage parts. Therefore, the beam structure of the base body on the side facing the non-suction passage is a fixed beam structure with both ends fixed, whereas the beam structure of the base body on the side facing the suction passage is a support beam structure with both ends free. As a result, the deflection of the base body on the side facing the suction passage becomes large due to the compressed fluid pressure acting on the back surface of the base body and the weight of the base body and the spiral body, making it difficult to manage between the spiral bodies of the fixed scroll and the revolving scroll. There is a problem.
