<P>PROBLEM TO BE SOLVED: To provide a rubber boot for a constant velocity joint that can avoid interference between a staking protrusion part and a bellows part when a fastening clamp having the staking protrusion part is used. <P>SOLUTION: In a cross section containing an axial center O of the rubber boot 10, a distance in a radial direction K between the apex 28a of a first crest 28 adjacent to a small diameter cylinder part 12 and the bellows side opening end 18a of a clamp recessed groove 18 is defined as A; a distance in the axial direction X between the apex 28a of the first crest 28 and the bellows side opening end 18a of the clamp recessed groove 18 is defined as B; the radius of curvature of a connection part 40 having a circular cross section connecting between the outer slope 28b of the first crest and the outer periphery 12a of the small diameter cylinder part is defined as C; and the length of a perpendicular line q drawn from an inner slope 28c to the outer slope 28b of the first crest part with a boundary portion P between the connection part 40 and the outer slope 28b as the foot of the perpendicular line, is defined as D, and following relations are set: B/A≥0.80, C/A≥0.32, and D/A≥0.26. <P>COPYRIGHT: (C)2013,JPO&INPIT |
