PROBLEM TO BE SOLVED: To provide an inexpensive compressor having a hypocycloid mechanism and enabling the number of components thereof to be reduced.SOLUTION: The compressor includes: a crankshaft (10); a bearing (12); a case (20); an outer ring gear (30) arranged so as to surround the crank shaft (10); a planetary gear (42) the pitch circle of which has a radius set to a 1/2 of a radius of a pitch circle of the outer ring gear (30) and in which the crank shaft (10) is inserted so that the planetary gear (42) is rotated relatively to the crank shaft (10); a piston (50) which is connected to the planetary gear (42) so as to rotate relatively to the planetary gear (42) and which reciprocates in the case (20) along a direction parallel to a radial direction of the outer ring gear (30) by rotation of the planetary gear (42) in the outer ring gear (30) while the planetary gear (42) engages with the outer ring gear (30); and a pump (60) for supplying lubrication oil to the bearing (12), wherein the pump (60) is housed in the case (20). 【課題】ハイポサイクロイド機構を有しており、低コストで部品点数を削減可能な圧縮機を提供すること。【解決手段】クランク軸（１０）と、軸受（１２）と、ケース（２０）と、クランク軸（１０）を取り囲むように配置された外輪歯車（３０）と、そのピッチ円の半径が外輪歯車（３０）のピッチ円の半径の２分の１に設定されており、クランク軸（１０）に対して相対回転するように当該クランク軸（１０）を挿通する遊星歯車（４２）と、遊星歯車（４２）に対して相対回転するように当該遊星歯車（４２）に接続されており、遊星歯車（４２）が外輪歯車（３０）と噛み合いながら当該外輪歯車（３０）内を回転することによりケース（２０）内を外輪歯車（３０）の半径方向と平行な方向に沿って往復運動するピストン（５０）と、軸受（１２）に潤滑油を供給するためのポンプ（６０）とを備え、ポンプ（６０）は、ケース（２０）内に収容されている圧縮機。【選択図】図１
