An outer ring (31) has a small-diameter stepped part (37) comprising a stepped part outer peripheral surface (37a) and a step-difference surface (37b), and a locking groove (37c) is formed in the stepped part outer peripheral surface (37a). The inner peripheral surface of a fixing plate (40) is provided with a small-diameter hole part (41) facing the stepped part outer peripheral surface (37a), and a large-diameter hole part (42) facing the outer peripheral surface (31a) of the outer ring (31) and guiding a rolling bearing (30). The fixing plate (40) is provided with a plurality of locking pawls (49) for locking into the locking groove (37c), the locking pawls protruding diametrically inward from the inner periphery of the small-diameter hole part (41), and the fixing plate (40) and the rolling bearing (30) are inseparably assembled by locking the locking pawls (49) into the locking groove (37c). |
