Abstract
A variable-displacement compressor includes a wobble member for driving a pistons, and a rotation member for wobbling the wobbling member, a first support portion for supporting a wobbling member in such a manner that the angle of wobbling of the wobbling member is variable, and a second support portion for supporting said rotation member in such a manner that the angle of tilt of said rotation member relative to a main shaft is variable. With this construction, unbalanced inertia forces can be reduced greatly, thereby providing the variable-displacement compressor which produces less vibrations and noises.
