A water pump has a pump housing () having therein a pump chamber (); a drive shaft () rotatably supported in the pump housing (); a pulley () having a flange wall () fixed to one end portion of the drive shaft (), the pulley () being formed integrally with the drive shaft () with synthetic resin material containing glass fiber material (); and an impeller () secured to the other end portion of the drive shaft () so as to be able to rotate integrally with the drive shaft (), the impeller () being accommodated in the pump chamber (). Six penetration holes () are formed at the flange wall (), and the glass fiber material () existing around the penetration hole () is oriented at random. With this, decrease in strength of the pulley () can be suppressed.

A housing () of a compressor () according to the present embodiment includes at least one compression chamber () that compresses a gas aspirated into the inside thereof and is composed of a metal-resin composite () in which a resin member () composed of a thermosetting resin composition and a metal member () are bonded to each other. In a case where the metal-resin composite () is made into a test piece in which the resin member () having a thickness dand the metal member () having a thickness dare laminated on and bonded to each other and a ratio of d/dis 3, and the test piece is put in a first state where the test piece is disposed, the surface on the resin member ()-exposed side up, on two supports with no stress applied thereto and a second state where a 1-point bending stress of 140 MPa is applied in a thickness direction to the center of the surface on the resin member () side such that the center caves in after the first state, when putting in the first and second states is alternately repeated 1,000,000 times at a frequency of 30 Hz under a temperature condition of 25&#xb0; C., the metal-resin composite exhibits bending fatigue resistance in which neither peeling nor fracture occurs.
