PROBLEM TO BE SOLVED: To provide an air compressor that suppresses a deterioration in sealability by changing wall thickness of a tip with respect to wall thickness of a bent part in a circumferential direction.SOLUTION: An air compressor is characterized in that a lip part and a bent part are formed in such a shape that wall thickness of the lip part is smaller than that of the bent part, in a part, nearer to a cylinder head than to a central part of a lip ring in a compression stroke in which a piston compresses air in a cylinder, of the lip ring. |
