摘要： The present invention provides a boot for a constant velocity universal joint that is compact in shape and can prevent a bellows section from becoming caught at an inner ring opening section. The present invention is the boot for a constant velocity universal joint including a large diameter section 11 that is attached to an opening end section of an outer joint component 4 of a constant velocity universal joint 2, a small diameter section 12 that is attached to a shaft connected to an inner joint component 6 of the constant velocity universal joint 2, and a bellows section 13 that is provided between the large diameter section 11 and the small diameter section 12 and has peaks 16 and valleys 15 alternately disposed along an axial direction. A peak 16 is provided adjacent to the large diameter section 11 and the small diameter section 12. With a peak and valley 16 and 15 in an axial direction center section as reference, thicknesses of peaks and valleys 16 and 15 to the small diameter section 12 side of the reference peak and valley 16 and 15 are thinner than a reference thickness of the reference peak and valley 16 and 15. Thicknesses of peaks and valleys 16 and 15 to the large diameter section 11 side of the reference peak and valley 16 and 15 are thicker than the reference thickness.
