SILICONE BOOT FOR CONSTANT VELOCITY UNIVERSAL JOINT AND CONSTANT VELOCITY UNIVERSAL JOINT |
摘要 |
Provided are a silicone boot for a constant velocity universal joint and a constant velocity universal joint, in which occurrence of cracks in a smaller diameter portion of the boot is suppressed and durability thereof is improved. The silicone boot for a constant velocity universal joint includes: a larger diameter portion (13) attached to an outer joint member (2) of a constant velocity universal joint; a smaller diameter portion (14) attached to a shaft (9) coupled with an inner joint member (4) of the constant velocity universal joint; and a bellows portion (15), which is arranged between the larger diameter portion (13) and the smaller diameter portion (14), and has peak portions (7) and valley portions (6) formed alternately with each other. The smaller diameter portion (14) includes: a shaft attachment portion (37) having a radially outer surface in which a fitting groove (19) for attachment of a boot band is formed; and a thin portion (38) extending from the shaft attachment portion (37) so as to be coupled with the bellows portion (15) through intermediation of a thick portion (25) and allowing buckling deformation with respect to the shaft attachment portion (37) and the bellows portion (15). |
