ようになつている。 The back plate 15 has a cylindrical grease retainer 1 surrounding the outer periphery of one end of the wheel hub 2.
8 is fixed. In addition, a grease escape hole 20 is bored in a portion of the back plate 15 that is located radially inward from the grease retainer 18.
In addition, the flange portion 14 of the nutkl spindle 1 has a grease hole 2 that aligns with the grease hole 20.
1 is drilled. That is, grease retainer 1
8 surrounds the outer periphery of one end of the wheel hub 2 at a position where the grease hole 20 is radially inward.

接近して位置するようになつている。 A baffle plate 19 is fixed to the grease retainer 18, as clearly shown in FIG. This baffle plate 19 is composed of a curved band plate having a predetermined width, and when the grease retainer 18 is attached, it is located radially inward from the grease outlet hole 20, that is, at the wheel hub, as shown in FIGS. 1 and 2. 2
The wheel hub 2 is located very close to the lower outer circumferential surface of the wheel hub 2 at a position on the side of the wheel hub 2.

になる。 By providing the baffle plate 19 as described above, a labyrinth seal is formed between the baffle plate 19 and the outer peripheral surface of the wheel hub 2, and water that has entered into the grease retainer 18 through the grease holes 21 and 20 can be removed from the wheel. It becomes difficult for the water to collide with the outer peripheral surface of the hub 2, making it difficult for splashes to occur, and it also becomes difficult for the droplets to scatter to the part where the seal member 11 is attached, and as a result of these, water passes through the seal member 11 and enters the wheel hub 2. Intrusion will now be avoided.
