Claims

[Claims for Utility Model Registration] (1) A crankshaft or rotor shaft that is rotatably incorporated into the bearing housing of the compressor body, and a crankshaft or rotor shaft that is placed in contact with the end face of the crankshaft or rotor shaft and receives axial thrust. In a compressor including a thrust bearing and a C-shaped retaining ring fixed in the bearing housing so as to support the thrust bearing, the bearing housing has an inner diameter of the housing portion of the thrust bearing in the shaft housing. A compressor characterized in that an oil groove is formed to be larger than the inner diameter of the oil groove and opened inward along the axial direction, and the thrust receiver is provided with a convex portion that hangs over the oil groove. . (2) A crankshaft or rotor shaft that is rotatably incorporated into the bearing housing of the compressor body, a thrust bearing that is placed in contact with the end surface of the crankshaft or rotor shaft and receives axial thrust, and this thrust bearing. In a compressor equipped with a C-shaped retaining ring fixed in the bearing housing so as to support the bearing housing, the bearing housing has an inner diameter of a portion where the thrust bearing is attached and a portion where the crankshaft or rotor shaft is installed. A compressor characterized in that a bearing hole is formed so that its inner diameter is eccentric.
