Abstract
PURPOSE: To prevent the ineffectiveness of clamping by means of a tapping screw, by stabilizing clamping torque by erecting a projection of synthetic resin with large hardness on a substrate, by drilling a hole portion with a non-circular section in the base side from an upper end of the projection and by screwing the tapping screw into the hole portion.
CONSTITUTION: A columnar projection 2 of synthetic resin, of the same materials a substrate 1 and which hardness is large, is erected on both sides of the substrate 1, a hole portion 3 with an oval section is provided over the base side of the projection from the center of an upper end surface of the projection 2 and a diameter of a slot 4a of a tapping screw 4 is formed in a shape that it is smaller than a long diameter 3b of the hole portion 3 and larger than a short diameter 3a. Thus, a hole portion 6 of a mounting plate 5, to which the hole portion 6 is drilled, is made of conformed to the hole portion 3, the tapping screw 4 is inserted into the hole portion 3 from the hole portion 6 and the mounting plate 5 is clamped between the head portion 4 and the projection 2. Since the hole portion 3 is non-circular, void portions are formed and engaging width becomes large, screwing-in is smoothered clamping torque is stabilized.
