よるシール機構が配設されている。 An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figure 2, water pump 1
The rotor 11 of 0 is a shaft 1 supported by a bearing 12.
3, and a well-known mechanical sealing device 14 is disposed between the bearing 12 and the rotor 11. This sealing device 14 has a ceramic plate 14 attached to a holding member 14a attached to the rotor 11.
b is fixed, and a carbon sliding member 14e attached to a bellows 14d on a holding member 14c fitted to the body member 15 is pressed against the face plate 14b by a spring 14f. A sealing mechanism according to the present invention is disposed between the sealing device 14 and the bearing 12.

た水抜穴を示す。 The sealing member 16 of this sealing mechanism is fixed on the shaft 13 by a cylindrical part 16a, and has a tongue part 16b.
It is in sliding contact with the side surface 15a of the body member 15 at. Furthermore, a space 16c is formed in the tongue 16b, and this space 16c is filled with grease 17. As shown in FIG. 4, a plurality of notches 16e communicating with the space 16c are formed on the sliding surface 16d of the tongue 16b that contacts the body member 15. As shown in FIG. Incidentally, as shown in FIG. 5, the tongue portion 16b
At the tip of the projection 1, the projection 1 surrounds the space 16c.
6f may be formed to increase the grease holding power. Note that 18 indicates a drain hole formed in the body member 15.

and be lubricated. At this time, the grease 17 stored in the space 16c is constantly replenished onto the sliding surface 16d of the seal member 16 as the shaft 13 rotates. Note that the rotor 1 is heated by frictional heat (20°C to 30°C) generated by friction between the plate 14b and the sliding plate 14e of the mechanical sealing device 14.
One portion of the water (80° C. to 120° C.) turns into water vapor and flows toward the bearing 12, but is blocked by the seal member 16 and released from the drain hole 18 to the outside.
