Abstract
A closed compressor includes: a compressor body; and a closed vessel in which the compressor body is accommodated and oil is stored. The compressor body has an electric element and a compression element that is driven by the electric element. The compression element has a cylinder block that forms a cylinder, a piston that performs a reciprocating motion in the cylinder, and a crankshaft that actuates the piston. The cylinder block configures a bearing that pivotally supports the crankshaft. The cylinder forms a compression chamber. The compressor body has a support that forms a curved surface. A contact portion, at which the curved surface comes into contact with a receiving surface in the closed vessel, is formed.
