PROBLEM TO BE SOLVED: To provide a boot for a constant velocity joint which can suppress the generation of a scratch sound from a bellows part of the boot at the operation of the constant velocity joint. ! SOLUTION: In a boot 70 for a constant velocity joint having a bellows part 71 which is obtained by alternately and continuously forming crest parts 71a to 71g and trough parts 71h to 71m, an apex side of the crest part shifted to a prescribed position Q of an inclined face at an external peripheral side which connects an apex of the crest part and a trough bottom of the trough part is defined as an apex side inclined face Gt, a trough bottom side of the trough part shifted to the prescribed position Q of the inclined face at the external peripheral side is defined as a trough bottom side inclined face Gbo, and the boot for the constant velocity joint comprises a bent point formation part arranged at an internal peripheral face side of at least one crest part. The bent point formation part 74 forms a spac |
