PROBLEM TO BE SOLVED: To provide a reciprocation compressor capable of reducing stress related to a lip ring, and capable of improving the service life of the lip ring.SOLUTION: A reciprocation compressor includes: a piston that reciprocates in a cylinder while oscillating, to compress air; and a seal member that is mounted to a groove formed in the piston and seals between the cylinder and the piston. The seal member has a bottom surface part fitted into the groove of the piston, and a side surface part provided on the radial outside of the piston. The side surface part is provided with a bent part, and a gap between the tip side of the side surface and the piston is made small. |
