Provided is a screw compressor (1) in which a screw rotor (40) and a hydraulic cylinder (87) for slide valve driving are disposed on either side of bearings (36), wherein in order to reduce the size and weight of the screw compressor (1) by shortening the axial direction length of a bearing holder (35) that holds the bearings (36) which support a drive axle (21), and that has an outer surface that serves as a guide surface (37) for operation of a slide valve (70), an end part of the bearing holder (35), the end part being opposite to the screw rotor (40), forms a cylinder tube (81) of the hydraulic cylinder (87), and the bearing holder (35) and the hydraulic cylinder (87) are formed integrally. |
