PROBLEM TO BE SOLVED: To provide a bearing preload mechanism which is made compatible in both handling performance when installed in a bearing box, and the exchange workability of a spring member.SOLUTION: A spring member 14 is gripped by both divided cases 11, 12 in an axial direction. A screw part 15b is integrally arranged at one divided case 11, a support shaft part 16 is made to penetrate the other divided case 12 in a slidable penetration state in the axial direction, and the support shaft part 16 and the screw part 15 are screwed to each other. A lock portion 18 which is locked to the other divided case 12 in the axial direction is formed at the support shaft part 16. The separation of both the divided cases 11, 12 is limited in the axial direction by the screw part 15, the support shaft part 16 and the lock portion 18, and both the divided cases 11, 12 are connected to each other so as to maintain the grip of the spring member 14, and assembled into a unit.SELECTED DRAWING: Figure 1 |
