PURPOSE:To prevent abrasion by forming a bearing for supporting the part close to a crank part engaged with a turning scroll in a crankshaft part into a slide bearing having pads which form a circular bearing surface divided in the peripheral direction. CONSTITUTION:The upper part of the shaft part 9a of a crankshaft 9 in the lower part of a turning scroll 3 is supported by a slide bearing 11 installed onto a frame 10. The slide bearing 11 consists of a plurality of pads 11a which form a circular bearing surface divided in the peripheral direction, ring-shaped body 11b, and a side cover 11c. Therefore, the bearing load and the one-sided contact of the bearing can be reduced, and the abrasion of the bearing can be reduced.
