PROBLEM TO BE SOLVED: To provide a resin joint boot having excellent durability and suppressing generation of a crack in a recessed part for fixing a small diameter cylindrical part. SOLUTION: This resin joint boot 10 comprises: a small diameter cylindrical part 12; a large diameter cylindrical part 14 disposed separately from and coaxially with the small diameter cylindrical part 12; and a bellows part 16 integrally connecting the small diameter cylindrical parts 12 and the large diameter cylindrical part 14. A fixing recessed part 20 for receiving a fastening clamp 4 is formed on the outer circumferential surface of the small diameter cylindrical part 12, a cutout part 24 is formed by cutting bellows part side shoulder part 20c of the fixing recessed part 20 on the total periphery, and the volume of bellows part side shoulder 20c of the fixing recessed part 20 is reduced by the cutout part 24 to relax the stress applied to an end part 20a on the bellows part side of the recessed part 20.
