To secure sealability in a fixing part, when a large-diameter end part of a boot having thin parts and thick parts arranged alternately in a circumferential direction is fixed to an outer periphery of an outside joint member.SOLUTION: A method for fixing a boot of a constant velocity universal joint has a step of fitting a boot 20 to the outer periphery of an outside joint member 2, a step of winding a boot band 100 around the outer periphery of the boot 20, and a step of contracting the boot band 100 to tighten the boot 20. A portion (ear part 111) of the boot band 100 to which inward pressing force is applied when the diameter of the boot band 100 is contracted is arranged within a circumferential region R of a thin part 21S of the boot 20.SELECTED DRAWING: Figure 3 【課題】薄肉部及び厚肉部を周方向で交互に有するブーツの大径端部をブーツバンドで外側継手部材の外周に固定するに際し、固定部におけるシール性を確保する。【解決手段】外側継手部材２の外周にブーツ２０を嵌合させる工程と、ブーツバンド１００をブーツ２０の外周に周回させる工程と、ブーツバンド１００を縮径させてブーツ２０を締め付ける工程とを有する。ブーツバンド１００のうち、ブーツバンド１００を縮径させる際に内径向きの押圧力が加わる部位（耳部１１１）を、ブーツ２０の薄肉部２１Ｓの周方向領域Ｒ内に配する。【選択図】図３
