Abstract:
An attachment structure for a joint boot for attaching said joint boot to an outer cup of a constant velocity universal joint, said attachment structure comprising:an inclined surface formed at a circumferential end of an opening of said outer cup; a bellows section of said joint boot: a thick-walled section of said joint boot, having a wall thickness that is thicker in comparison to a wall thickness of said bellows section, said thick-walled section being made of an elastic material formed integrally at a circumferential end of said bellows section of said joint boot; and a fixture comprising a ring member to be forcibly mounted on an outer circumferential surface of said outer cup, said fixture having an annular stepped section for being engaged with said thick-walled section, wherein said thick-walled section pressed between said inclined surface of said outer cup and said annular stepped section of said fixture, said thick-walled section being elastically deformed by forcibly mounting said fixture attached with said joint boot on said outer circumferential surface of said outer cup, whereby said inclined surface and said elastically deformed thick-walled section are pressed in close contact with each other to effect a sealing function, and wherein said thick-walled section is compressed against said inclined surface such that compression forces are exerted on said thick-walled section in a direction opposite to a direction (A) in which said fixture is displaced to mount said fixture on said outer cup.
