項記載のスクロール形流体機械。[Claims for Utility Model Registration] 1. It has an orbiting scroll and a fixed scroll consisting of an end plate and a spiral wrap standing upright on the end plate, and both scrolls are combined with each other with the wraps facing inward, and each wrap is The scroll has a structure in which the scrolls move relative to each other so that the volume of the space formed by the end plate decreases as the space moves toward the center of the scroll, and a boss portion for holding the swing sliding bearing is protruded from the back surface of the end plate of the rotating Shumir. 1. A scroll fluid machine that operates by connecting a crank portion of a crankshaft to a pivot bearing, characterized in that the pivot bearing is provided so as not to be within the thickness of the end plate. 2. In a structure in which a sliding bearing is press-fitted into the boss portion of an orbiting scroll to form an orbiting bearing, the outer circumference of the sliding bearing may be made smaller only in the portion that is within the thickness of the end plate of the orbiting scroll, or the inner diameter of the boss may be increased to make them mutually compatible. Scroll-type fluid machine according to claim 1, characterized in that there is no contact. 3 In a structure in which a sliding bearing is press-fitted into the boss part of the orbiting scroll to form an orbiting bearing, the inner diameter of the sliding bearing is slightly increased only in the part that is within the thickness of the end plate of the orbiting scroll to avoid contact with the crankshaft surface. Scroll-type fluid machine according to claim 1, characterized in that: 4. Utility model registration claim 1, characterized in that the thickness of the entire circumference mirror plate is locally thinned on the outer periphery of the orbiting scroll boss so that the end face of the orbiting bearing does not fall within the thickness of the mirror plate.
Scroll-type fluid machine described in Section 1.
