<P>PROBLEM TO BE SOLVED: To provide a fixed wheel for a bearing and a bearing device for a wheel having the same, configured to reduce weight, without reducing installation strength of a bearing installing flange to a vehicle body. <P>SOLUTION: An outer ring 3 has a shaft-shaped body part 30 having a first inside raceway surface 30a for rolling a rolling element 4 and a second inside raceway surface 30b for rolling a rolling element 5, and the bearing installing flanges 31 and 32 arranged in parallel with each other in the body part 30 around its axis, installed on the vehicle body side of a vehicle by installation bolts 10 and 11 and having bolt inserting holes 31b and 32b for inserting the installation bolts 10 and 11. In the bearing installing flanges 31 and 32, a hole diameter of the bolt inserting hole 31b in the compression side bearing installing flange 31, is set in a dimension smaller than a hole diameter of the bolt inserting hole 32b in the tension side bearing installing flange 32. <P>COPYRIGHT: (C)2013,JPO&INPIT |
