Claims (1)

[Scope of utility model registration request] In a rotary compressor that has a rolling piston that rotates in a cylinder by an eccentric part of a rotating shaft, and in which the rolling piston and the eccentric part have different coefficients of thermal expansion, each rolling piston is formed of two separate members. , the coefficient of thermal expansion of the outer rolling piston in contact with the vane and the eccentric part is changed, and the coefficient of thermal expansion of the inner rolling piston in contact with the eccentric part is approximately the same as the coefficient of thermal expansion of the outer rolling piston or the eccentric part. A rotary compressor characterized by:
