ABSTRACT:
A boot assembly with adapter comprising a boot having elasticity and an adapter having relative rigidity. The boot is provided with a small diameter mount formed at one end to be fit over the outer circumference of the shaft, a connecting bead formed at the other end for connection to the adapter, and a body formed between the small diameter mount and the connecting bead. The adapter is provided with a large diameter mount formed at one end for connection to the joint and a connecting cavity formed at the other end and fitting with the connecting bead of the boot so as to surround the connecting bead. The connecting cavity of the adapter is provided with a bend formed with a step which protrudes outward in the radial direction and pressing against the inner circumferential of the connecting bead of the boot and a foldback connecting to the bend, formed folded back to the inner circumference of the bend, and folded over itself so that the front end is accommodated in the step. Even if the axial center of the shaft is inclined to the maximum with respect to the joint, it is possible to effectively prevent the body from being damaged by the front end of the adapter.
