Claims

[Scope of utility model registration request]

In a hermetic compressor, an electric element is arranged at the upper part and a compression element at the lower part in a closed container having an oil reservoir at the bottom, and the compression element is driven by the rotating shaft of the electric element. An oil supply hole is drilled in the center of the rotating shaft, an oil hole communicating with the oil supply hole is opened on the outer circumference of the eccentric part of the rotation shaft, and an oil groove communicating with the opening of the oil hole is opened on the outer circumference of the eccentric part. An oil supply device for a hermetic compressor, characterized in that the surface is formed in a dogleg shape, and the opening of the oil hole is located at the bent part of the oil groove.
