In a sealed type scroll compressor including an intermediate pressure chamber in which a pressure intermediate in magnitude between a discharge pressure and a suction pressure prevails, a bearing device including a roller bearing and a plain bearing mounted on a frame for supporting a shaft section of a crankshaft.
