摘要： A bellows-form boot for universal joint which is formed integrally of a le-diameter cylindrical portion and a small-diameter cylindrical portion at both ends, the former being adapted to be fitted to a joint case housing therein the universal joint and the latter to a driving shaft, a central annular bellows portion having ridge portions whose diameters are tapered down toward the small-diameter portion, and a bracing boss portion extending between the large-diameter portion and the bellows portion. The boss portion has a wall thickness of 2 to 3 times the average wall thickness of the bellows portion and is profiled so that the inner face thereof may abuttingly contact with the edge face of the joint case and the outer face thereof is flush with the outer face of the bellows portion in the mutual joining area. The bellows portion has, at its zone adjacent to the boss portion extending from the end to the crest of the first ridge portion thereof, wall thicknesses gradually increasing from the latter to the former, whose maximum is a half the wall thickness of the boss portion.
