If a large impact force is applied to the dust cover 7 when it is dropped during transportation, etc., the dust cover will tilt with respect to the sliding yoke 4, but unlike the conventional example, in this case, the dust cover will first tilt. The inner circumferential surface 7e of the small diameter support portion 7d contacts the outer circumferential surface 4a of the sliding yoke 4, and at this time, the gap C2 between the inner circumferential surface 7f of the circular opening 7b and the outer circumferential surface 4a of the sliding yoke 4 is equal to the gap C, and the gap C is the lip part 8 of the dust seal 8.
Since the thickness of a is the same as or greater than t, the lip portion 8a is not pinched by the circular opening 7b and therefore is not damaged.

び組立ての容易化も同時に達成できる。 As described above, the present invention forms a circular opening having a diameter larger than the diameter of the other sliding yoke and a dust seal accommodating recess having a larger diameter than the circular opening at the tip of the dust cover, and A small-diameter support portion having a smaller diameter than the circular opening is formed, and a gap between the inner circumferential surface of the small-diameter support portion and the outer circumferential surface of the sliding yoke, and a gap between the inner circumferential surface of the circular opening and the outer circumference of the sliding yoke. The difference in the gap between the dust cover and the dust cover is made equal to or greater than the thickness of the lip of the dust seal, which prevents the dust seal from being damaged even if impact is applied to the dust cover during transportation of the propeller shaft. The effect that can be obtained can be obtained. Furthermore, since the conventionally used seal ring is no longer necessary, the number of parts can be reduced and assembly can be facilitated at the same time.
