ル。A case having a cylindrical portion on a shaft portion, a protrusion formed on the cylindrical portion to protrude outward in the radial direction, and a driven ring slidably provided in the axial direction with respect to the cylindrical portion including the protrusion. is interposed between an annular groove formed on the inner periphery of the driven ring and the inner wall surface of the annular groove and the protrusion to maintain liquid tightness between the driven ring and the case and to prevent the driven ring from being removed. A mechanical seal for a water pump, comprising: an annular seal member having elasticity serving as a stop member; and a spring that is elastically loaded between the case and the driven ring and brings the driven ring into elastic contact with the seal plate, the seal member A mechanical seal for a water pump characterized by having a circumferential angle of 135 degrees or less within which it does not come into contact with protrusions.
