PURPOSE:To suppress eccentric wear of a bearing and inclination of a moving object by making the bearing in contact with either of two parallel shafts with possibility for fine motion, and using one of the bearings in contact with the other shaft as a member to prevent inclination of moving object. CONSTITUTION:Slide bearings 5, 6 in slide fitting on a center shaft 2 are fitted in a hole 16 of a bracket 1a for a moving object 1 and fixed by shaft stop rings 8, 9. A slide bearing 7 in slide fitting on a follower shaft 3 is fitted in a horizontal long hole 17 of an upper bracket 1b for the moving object 1 and received by a shaft stop ring 10. A lower roller 11 is fixed to a lower bracket 1c on the follower shaft 3 side of the moving object 1. Here the slide bearings 5, 6 are fine movable with respect to the moving object 1, which will relieve the pressures C, F applied to the end faces of the slide bearings 5, 6 through inclination of the moving object 1. Also the lower roller 11 contacts said fol lower shaft 3 at one point within the surface of moving object 1 where inclina tion occurs, which will prevent inclination of the object 1 in the B direction.
