Abstract
A method for fixing a boot of a constant velocity universal joint includes fitting the boot to an outer periphery of an outer joint member, causing a boot band to circle around an outer periphery of the boot, and fastening the boot by reducing a diameter of the boot band. A portion of the boot band to which a pressing force in an inner diameter direction is applied when the diameter of the boot band is reduced is arranged in a circumferential region of a thin portion of the boot.
Claims12
A constant velocity universal joint comprising:
- an outer joint member;
- an inner joint member provided in an inner periphery of the outer joint member;
- a boot including a large-diameter end attached to an outer peripheral surface of the outer joint member;
- and
- a boot band for fastening and fixing the large-diameter end of the boot to the outer peripheral surface of the outer joint member,
- wherein the large-diameter end of the boot has a thin portion and a thick portion alternately in a circumferential direction, and
- wherein a portion of the boot band to which a pressing force in an inner diameter direction is applied when fastening and fixing the boot to the outer joint member is arranged in a circumferential region of the thin portion of the large-diameter end of the boot.
