An outer-ring-equivalent component (2) having an annular raceway surface (2a) on which rolling elements (5) roll is disposed on an outer circumference of a bearing (3). The bearing (3) is, for example, a retainer-equipped roller. Between the bearing (3) and a fixed member (7) located apart from the bearing (3) in an axial direction, a thrust washer (4) is interposed so as to be movable in the axial direction. A gap forming device (10) is provided which constantly forms a gap (11) between the thrust washer (4) and the outer-ring-equivalent component (2). For example, as the gap forming device (10), an axial width (J) of the bearing (3) is made larger than an axial width (G) of the outer-ring-equivalent component (2). |
