Abstract
A rotary compressor has a blade which is provided in a cylinder so that reciprocating movement can be performed. The blade partitions a cylinder chamber into a suction chamber and a compression chamber by making a tip end portion of the blade contact the outer peripheral surface of a roller. The blade includes two blade members provided so as to be superimposed in an axial direction of a rotary shaft. Tip end portions of the two blade members are made to contact the outer peripheral surface of the roller. The two blade members are energized by a coil spring so that superimposed portions of the blade members are made in contact.
