RESIN BOOT FOR CONSTANT VELOCITY JOINT

摘要

PROBLEM TO BE SOLVED: To apply fastening force generated by fastening one end annular fastening part to a non-circular gear housing with a predetermined fastening band as load uniform and vertical to the outside surface shape of the gear housing. SOLUTION: At least the outer peripheral surface (the outer peripheral surface 6bs of a band applied part 6b) of one end annular fastening part P3 where a thick part T1 is disposed is provided with an action plane part 44 integrally formed with a curvature larger than the curvature of the outer peripheral surface of the one end annular fastening part outside of the thick part. The shape of the action plane part may be a substantially curved surface having a predetermined curvature or a substantially flat surface having a predetermined curvature. In either shape, when the one end annular fastening part is fitted to the gear housing 2b and fastened by one end fastening band 4b, a gap is formed between the action plane part and the one end fastening band. As to this gap, when the maximum value of the gap is t, the gap is set to satisfy the relationship expressed by 0
