Patent abstract
A flexible section is provided between a small-diameter tube section and a bellows section of a boot for a joint, and the flexible section has a greater flexibility than the small-diameter tube section. When a spline shaft is displaced so as to incline relative to a constant velocity joint, deformation stress acting in the boot is relaxed by allowing the flexible section to deflect (bend). This inhibits the inner wall surface of the small-diameter tube section from separating from the sidewall surface of the spline shaft.
