ROCKING BEARING OUTER RING, ROCKING BEARING, AIR DISC BRAKE DEVICE, AND FITTING STRUCTURE OF ROCKING BEARING OUTER RING

摘要

A rocking bearing outer ring (12) includes an arcuate track member (13) having a track surface on its inner diameter surface, and a flange portion (14) projecting radially inward from each widthwise end portion of the track member (13). In addition, when it is assumed that L1 represents a circumferential length of the track member (13) and L2 represents a circumferential length of the flange portion (14), 0.2≦̸L2/L1≦̸8 is satisfied.
