Definitions

  • FIG. 9 is a fragmentary front elevation showing an essential part of an eighth embodiment of the water pump according to the present invention.
  • a front bearing seal 19 a and a rear bearing seal 19 b are respectively disposed at the front and rear end portions of inner and outer races 5 a, 5 b in order to prevent penetration of ducts and the like into the ball bearing 5 .
  • Each bearing seal 19 a, 19 b is formed of an annular rubber material and has an outer peripheral portion fixed to an axial end portion of outer race 5 b and an inner peripheral portion slidably secured to an axial end portion of inner race 5 a thereby accomplishing sealing for the inside of ball bearing 5 .
  • first two annular step portions respectively including outer peripheries 22 a, 22 b are formed around first annular face 22
  • second two annular step portions respectively including outer peripheries 23 a, 23 b are formed around second annular face 22 .
