<p>PURPOSE: To prevent the impossibility of adsorbing axial deflection in one direction by constituting an adjustment nut of an approximately square block body and a clip board having a pair of blade parts, and sandwiching a nut fixing hole by a projection face and a support provided in both of them. CONSTITUTION: An adjustment nut 2 is inserted from a clip board 23 to a nut fixing hole 11a to be fixed to the hole 11a. In this case, a blade part 23a of the board 23 is bent in such a state as narrowing its angle of approximately V shape, passed the hole 11a, and when it reaches a rear face 11c, it is enlarged by elasticity. And the upper plane of a block body projecting face 21c and the upper plane of the wing part projecting face 23d are contacted with a surface 11b and the rear face 11c of the hole 11a respectively so as to sandwich the board thickness (T) with performing engagement. A little size difference in the board thickness (T) is absorbed by deflection of the blade part 23a and the nut 2 is in an erecting state to the hole 11a so that it can be held at a right position for threaded engagement with an adjustment screw 3, which is performed afterward.</p> |
