PROBLEM TO BE SOLVED: To provide a compressor in which rotational vibration and vibration caused by imbalance of a converting mechanism around an axis line of a rotary shaft is reduced, and a size and weight are also reduced. SOLUTION: A swash plate 20 is integrally and rotatably connected to a rotation supporting body 19 fixed to the rotary shaft 16 via a hinge mechanism 21 provided on a top dead point side around the axis line of the rotary shaft 16. A pulley 17 integrally and rotatably fixed at a front end part of the rotary shaft 16 is provided with a plurality of rollers 47 separated by prescribed intervals from a rotation center axis line of the pulley 17 and performing pendulum motions with an axis line parallel to the axis line as a center. In each of the rollers 47, mass distribution (number) is set to be larger on a bottom dead point side than that on the top dead point side. As a result, imbalance of the converting mechanism due to providing of the hinge mechanism 21 on the top dead point side is cancelled by the rollers 47 whose mass distribution on the bottom dead point side is set to be larger than that on the top dead point side.
