PROBLEM TO BE SOLVED: To provide a sealing structure for a constant velocity universal joint boot, having stable sealing function over a long period while suppressing the degradation of the sealing performance when used under high temperature environment. SOLUTION: The sealing structure is provided between a shaft 9 connected to the inside joint member of a constant velocity universal joint 2 and the constant velocity universal joint boot 1. A plurality of peripheral protruded portions 23, 24, 25 are provided on a boot mounting portion 22 of the shaft 9. In such a boot mounted state that a boot band 18 is fastened to a shaft fixing portion of the boot 1, a boot compression set amount with at least one peripheral protruded portion 25 is different from a boot compression set amount with each of the other peripheral protruded portions 23, 24.
