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) has tripod constant-velocity joints (10a, 10b) coupled to respective ends of a shaft (14) in opposite phase. Outer members (12) of the tripod constant-velocity joints (10a, 10b) and portions of the shaft (14) are covered with boots (22). When the large-diameter tube (18) of each of the boots (22) is fastened to the corresponding outer member (12) by a first fastening band (24), a band crimping ratio is managed so as to fall within a predetermined range. Each of the outer members (12) has a boot mount (20) whose shape is selected to satisfy predetermined equations.
