Claims

[Claims for Utility Model Registration] 1. The lap of the fixed scroll and the lap of the orbiting scroll are engaged to form a closed space, and the orbiting scroll is prevented from rotating by a plurality of pin cranks on its outer periphery, and its axis is The end plate has a sanderch structure to restrict the range of movement in the direction, and the rotating scroll drive main shaft engages with the center of the orbiting scroll and has a fixed rotation radius. In a scroll-type fluid machine that performs compression, separate thrust receiving members are provided on both sides of the orbiting scroll end plate at positions corresponding to the Sanderarch structure, on the frame at a position opposite thereto, and on the fixed scroll surface. At the same time,
The thrust receiving member on the side where the bearing for supporting the pin crank is provided has an annular flat plate shape divided into a plurality of parts, and the pin crank bearing is located at the divided part of the thrust receiving member, A scroll vacuum pump characterized in that, when the inner and outer annular edges of the thrust receiving member are extended concentrically, the bearing is disposed within the extension line. 2. In the scope of claims for utility model registration, as described in paragraph 1, the thrust receiving member has a base metal made of the same type of material as each base material, and a base metal whose main components are tetrafluoroethylene resin and polyimide resin. A scroll-type vacuum pump characterized by being equipped with a composite polymer material.
