摘要： Provided is a mounting structure for a boot for a constant velocity universal joint, which is capable of ensuring a stable sealing performance at low cost. The resin boot (1) for the constant velocity universal joint includes a smaller-diameter end portion (2) and a larger-diameter end portion (3), each of which has a cylindrical shape. The smaller-diameter end portion (2) of the boot (1) is fixed to a shaft (17) constituting an inner member, and the larger-diameter end portion (3) is fixed to an outer joint member (11) serving as an outer member. An inner peripheral surface of the smaller-diameter end portion (2) of the boot (1) is integrally bonded to an outer peripheral surface of a boot-mounting portion (18) of the shaft (17) in an abutting state due to a physical interaction between a resin constituting the boot (1) and a metal constituting the shaft (17). Further, an inner peripheral surface of the larger-diameter end portion (3) of the boot (1) is integrally bonded to an outer peripheral surface of a boot-mounting portion (19) of the outer joint member (11) in an abutting state due to the physical interaction between the resin constituting the boot (1) and the metal constituting the outer joint member (11).
