Abstract
A silicone boot for a constant velocity universal joint includes a larger diameter portion attached to an outer joint member of a constant velocity universal joint, a smaller diameter portion attached to a shaft coupled with an inner joint member of the constant velocity universal joint, and a bellows portion, which is arranged between the larger diameter portion and the smaller diameter portion, and has peak portions and valley portions formed alternately with each other. The smaller diameter portion includes a shaft attachment portion having a radially outer surface in which a fitting groove for attachment of a boot band is formed, and a thin portion extending from the shaft attachment portion so as to be coupled with the bellows portion through intermediation of a thick portion and allowing buckling deformation with respect to the shaft attachment portion and the bellows portion.
