摘要：
A flatness of a part of a component formed of a resin material that faces a thrust bearing gap is easily increased. A housing (7) is injection-molded using a resin material and has a bottomed-cylindrical shape integrally including a cylindrical side portion (7a) and a flat bottom portion (7b). The resin material to be used for the injection molding of the housing (7) contains, as filler, a reinforcing fiber having a fiber diameter of 6 to 8 μm and an aspect ratio of 10 to 40.
