PROBLEM TO BE SOLVED: To achieve high efficiency by suppressing deformation of a piston and loss at a small end part in a hermetic compressor. SOLUTION: Width in an anti-compression chamber side 130 of the small end part 141 of a connecting means 119 is wider than width in a compression chamber side 151, and width in the compression camber side 151 of a pin hole 132 of the piston 118 is wider than width in the anti-compression chamber side 130. Since deformation of an outer circumference of the piston 118 can be suppressed and a sliding condition of the small end part 141 and a piston pin 133, an efficient and reliable hermetic compressor with reduced sliding loss can be provided.
