However, the above-described thin member mounting structures 1 and 5 have the following problems. That is, in the thin member mounting structure 1 shown in FIG. 3, the thin member 3 is positioned by the screw thread having poor dimensional accuracy of the tapping screw 4, so that the mounting hole 3 a of the thin member 3 and the base are formed. Even if the dimensional accuracy of the pilot hole 2a is good, accurate positioning becomes difficult. For example, the center of the mounting hole 3a is eccentric with respect to the center of the There was a problem that it was sometimes done.

According to the above construction, a thin member such as a leaf spring or a circuit board is placed at a predetermined position on the base, and the mounting hole of the thin member and the boss of the mounting portion of the base are aligned and clearance-fitted. The screw is inserted into the mounting hole of the thin member and screwed into the center hole of the boss. Thereby, the screw is tightened while pushing and expanding the center hole of the boss from the inside to the outside. Thus, the thin member is fixedly held at a predetermined position on the base.

In this case, since the center hole of the boss is formed slightly smaller in diameter than the screw, the boss expands outward with the screw tightening, and the final stage of the tightening is performed. As the projecting portion of the boss portion is crushed from above by the screw head, each section divided by the slit is expanded outward. Therefore, the boss portion comes into close contact with the inner surface of the mounting hole of the thin member. As a result, the boss portion is held without looseness in the mounting hole of the thin member, and the center hole is accurately positioned with respect to the center of the mounting hole of the thin member. The member can be accurately positioned and fixedly held without being displaced with respect to the base.

In this case, since the center hole of the boss portion is formed to have a slightly smaller diameter than the screw, the boss portion expands outward with the tightening of the screw and the final stage of the tightening. As the projecting portion of the boss portion is crushed from above by the screw head, each section divided by the slit is expanded outward. Therefore, the boss portion comes into close contact with the inner surface of the mounting hole of the thin member. As a result, the boss portion is held without looseness in the mounting hole of the thin member, and the center hole is accurately positioned with respect to the center of the mounting hole of the thin member. The member can be accurately positioned and fixedly held without being displaced with respect to the base.
