PROBLEM TO BE SOLVED: To provide a structure of a constant velocity joint boot which improves fatigue resistance and materializes long service life by minimizing the influence of material deterioration. SOLUTION: A boot 1 equipped with a tapered bellows part 2, small-diameter cylindrical part 3 and large-diameter cylindrical part 4, is divided into two divided piece 5A, 5B by an oblique wall part 8 between a trough part 6c and a crest part 7 in the bellows part 2. In the divided part, a recessed groove 9 on one side and a protruded part on the other side are fitted to each other in an uneven fitting shape to form a slide joining part 11, which secures the sliding degree of freedom.
