FLEXIBLE BOOT MADE OF RESIN AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a flexible boot made of resin which can not only suppress the generation of an initial noise but also improve a continuance effect when the boot is mounted on the constant velocity joint of an automobile and also when continuous rotation is effected in a state to be bent and displaced at a wide angle, and improve sealing ability and durability. SOLUTION: A flexible boot made of resin formed that a large port part 2 and a small port part 3 are intercoupled through a bellows part 4 is integrally molded by using a molding material where 0.5-5 pts.wt. mineral oil is blended in 100 pts.wt. thermoplastic elastomer resin material.
