<p><P>PROBLEM TO BE SOLVED: To reduce the progression rate of fastening looseness of a fastening bolt for connecting a hub shaft to a constant velocity joint by achieving an effect of holding bolt fastening force even after losing the structure of a torque-transmissive connection between the constant velocity joint and the hub shaft. <P>SOLUTION: Between a head 81 of the washer faced bolt 80 and a connection shaft section 73, a coil spring 90 is inserted in a compressed state for preventing the fastening looseness of the washer faced bolt 80. The coil spring 90 inserted therebetween in the compressed state is configured to develop a spring function in the compressed state until an engaging means disposed between a connection section of a joint outer ring 70 of the constant velocity joint 60 and that of the hub shaft 23 of a hub wheel 20 causes one connection section to be relatively isolated and displaced from the other in the axial direction to prohibit torque transmission. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
