ABSTRACT:
A boot fitting structure is fitted onto an axial component to protect it from a dirty environment including outside dust. The boot has a pair of annular grooves and an annular lip between the pair of annular grooves on an inner surface of the boot. The annular lip does not project from an inner surface toward a centerline of the boot. An annular protuberance is provided between the boot and a clamp, through which clamping force from the clamp is concentrated on the annular lip, so that the annular lip is elastically deformed and pushed toward outside of the axial component. Therefore, the axial component can be inserted into the boot without interference between the annular lip and the axial component. Furthermore, the annular lip is free from damage by interference between the annular lip and the axial component.
