Abstract
An object is to enable suppression of degradation of reliability by supporting a flange portion of a crankshaft with a bearing while downsizing a scroll compressor by reducing the size of the flange portion of the crankshaft. A scroll compressor includes: a fixed scroll fixed to a frame; an orbiting scroll forming a compression chamber by performing an orbital motion with respect to the fixed scroll; an electric motor that drives the orbiting scroll via the crankshaft; and a bearing part provided on the lower side from the flange portion of the crankshaft that rotatably supports a main shaft part of the crankshaft. The scroll compressor furthers has a thrust stopper, provided between the flange portion and the bearing part, in contact with the flange portion on the upper side and in contact with the bearing part on the lower side. Assuming that the outer diameter of the flange portionis φDt and the outer diameter of the thrust stopper is φDs, φDt<φDs holds.
