ROTATION DRIVE FORCE TRANSMISSION MECHANISM, CONSTANT VELOCITY UNIVERSAL JOINT AND RESIN JOINT BOOT CONSTRUCTING THE MECHANISM, AND METHOD OF TIGHTENING CLAMP BAND FOR CONSTANT VELOCITY UNIVERSAL JOINT

摘要

A rotation drive force transmission mechanism (10) where tripod constant velocity universal joints (10a, 10b) are connected in phases opposite to each other to the ends of a shaft (14), and a boot (22) covers from an outer member (12) of each tripod constant velocity universal joint (10a, 10b) to the shaft (14). When a large diameter tube section (18) of the boot (22) is tightened around the outer member (12) by a first clamp band (24), a band tightening rate is controlled to be in a predetermined region. Further, the shape of a boot installation section (20) of the outer member (12) is formed so as to satisfy a predetermined relational expression.
