Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a screw lock mechanism for adjustment capable of preventing change in perpendicularity of a rotation adjustment shaft in locking.SOLUTION: At a screw part 17b of a rotation adjustment shaft 17 projecting from a bearing part 11, an elastic body 12, a nut 13 and a ring 14 for locking are mounted in this order. Then, repulsive force of the elastic body 12 can be adjusted by fastening degree of a fitting screw 15, and the elastic body 12 is compressed according to the fastening degree of the screw 15. Since engagement degree between the screw part 17b and the ring 14 for locking and bearing part 11 varies according to compression degree of the elastic body 12, the rotation adjustment shaft 17 can be rotated by fastening degree of the fitting screw 15, or the rotation adjustment shaft 17 can be made into a locked state.SELECTED DRAWING: Figure 5
