A compressor according to the present invention comprises: a crank shaft; a bearing; a case; an outer wheel gear arranged to enclose the crank shaft; a planetary gear which is inserted to penetrate the crank shaft to rotate relatively with respect to the crank shaft, wherein a radius of a pitch circle is set to half the radius of a pitch circle of the outer wheel gear; a piston which is connected to the planetary gear to rotate relatively with respect to the planetary gear, wherein the piston reciprocally moves along a direction parallel with a radial direction of the outer wheel gear within the case, when the planetary gear is engaged with the outer wheel gear and rotates within the outer wheel gear; and a pump which supplied lubricating oil to the bearing. Hear, the pump is accommodated in the case.
