Claims

[Scope of utility model registration request]

A refrigerant compressor having a crankshaft with an oil supply path opening at the shaft end, a bearing rotatably supporting the crankshaft, and a bearing support supporting the bearing, which does not make contact with the shaft end of the crankshaft. By integrally molding a partition wall with the bearing support, a bearing chamber defined as an oil storage chamber is formed, and a communication hole is formed that communicates this bearing chamber with an oil reservoir in the crankcase. A refrigerant compressor, characterized in that a refrigerant compressor is provided with an oil supply pipe facing an opening at the shaft end of the crankshaft.
