A second connection member (21) is disposed on a radially outer side of the first thrust bearing (30) to face the second race (30b), and a restricting portion (21a) is disposed at a position facing the first race (30a) or the rolling body (30c) on the rolling element (30c) side of the second race (30b). A distal end of the restricting portion (21a) is located radially inward of a distal end of the flange portion (30d).
