摘要： A water pump has a pump housing 2 having therein a pump chamber 3; a drive shaft 7 rotatably supported in the pump housing 2; a pulley 5 having a flange wall 5a fixed to one end portion of the drive shaft 7, the pulley 5 being formed integrally with the drive shaft 7 with synthetic resin material containing glass fiber material 25; and an impeller 8 secured to the other end portion of the drive shaft 7 so as to be able to rotate integrally with the drive shaft 7, the impeller 8 being accommodated in the pump chamber 3. Six penetration holes 23 are formed at the flange wall 5a, and the glass fiber material 25 existing around the penetration hole 23 is oriented at random. With this, decrease in strength of the pulley can be suppressed.
