PURPOSE: To prevent the attitude of a roller from making disturbance caused by vibration by making one side of the conical surfaces of abacus ball type rolling element touch a fixed ring and making the other side thereof touch a turning ring and connecting the fixed ring to the turning ring turnably along a locus identical to the turning circle of the rolling element. CONSTITUTION: Holding members 2, 18 for composing the turning circle pockets 4, 7 of a roller 1 are fixed to a fixed ring 3 and a turning ring 12 by means of a caulking member 11. Connection members 9, 17 are formed in cylindrical shapes, forced and fixed in the holes of races from the direction of an arrow mark 19 with their flange parts 10 meshing each other so as to form a hook for preventing separation of the fixed ring 3 from the turning ring 12. The cylindrical outer peripheral surface 8 of a connection member 17 and the cylindrical outer peripheral surface of the flange parts 10 make mutual sliding motion and turn. The roller 1 makes sliding motion to the inner peripheral surface 5 of the roller turning pocket circle of the holding member 2 whose direction of deformation is limited by connection members 9, 17 and the inner peripheral surface 6 of the pocket circle of the turning ring 12. Accordingly, during conveyance and assembling work, the roller 1 is restrained by a surface 16 confronting to the pocket inner peripheral surface 5 and the race, so that its attitude may not be disturbed. |
