According to the figure, 3 is a rectangular parallelepiped case with a through hole on the top surface, 5 is a sliding body rotatably disposed within the case so that the operation part is exposed from the through hole, and the bottom surface of this sliding body A slider 6 having a multi-contact shape (for example, a bundle of wires) is held by heat welding or press-fitting. Also, 7 is a substrate on which a horseshoe-shaped resistor is formed. The mover 6 and the substrate 7 are in elastic contact.
また、基板７には、リード端子８が接続されており、基
板７の外側には樹脂９が充填されている。Further, lead terminals 8 are connected to the substrate 7, and the outside of the substrate 7 is filled with resin 9.
更にケース３と摺動体５の間には、Ｏリング４が介在し
ている。Furthermore, an O-ring 4 is interposed between the case 3 and the sliding body 5.
発明が解決しようとする課題
しかしながら、上記従来の可変抵抗器では、摺動子６が
基板７によって、常に圧力がかけられた状態にて、保持

板７に対する接触圧が減少し、また、接点位置にズレが
生しるという課題があった。Problems to be Solved by the Invention However, in the conventional variable resistor described above, the slider 6 is always held under pressure by the substrate 7, so it is difficult to apply heat stress such as soldering. In this case, the welded portion of the slider 6 would sag, the contact pressure of the slider 6 with the substrate 7 would decrease, and the contact positions would be misaligned.
課題を解決するための手段
本発明は、上記課題を解決するために、摺動体の酸形時

。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention, when the sliding body is in the acid form, attaches a flat metal plate by insert molding, and then attaches the tip of the metal plate along the outer surface. After bending, the other end of the metal plate is cut along the outer surface to form a slider on the slider by insert molding.
作用
したがって、本発明によれば、摺動子と摺動体とを一体
戒形したことにより、接点部に圧力がかかった状態で熱

のである。Therefore, according to the present invention, by integrally forming the slider and the slider, the slider is held even when thermal stress is applied with pressure applied to the contact portion. It is possible to prevent the parts from collapsing, and since the sliding body is bent along the outer surface of the sliding body, the distance to the contact points can be increased, so that bending of the contact points can be reduced.

である。According to the embodiment described above, there is an advantage that even when the slider 1 is subjected to thermal stress under pressure applied by the substrate 7, the base of the contact does not swell. Further, according to the above embodiment, since the slider l can be formed into a hoop shape using a metal plate, it has the effect of improving productivity.

。According to the figure, 2 is a sliding body in which the slider 1 is insert-molded, and a hoop-shaped metal plate la of FIG.
The slider 2 is insert-molded as shown in Fig. 1cI, and one end of the metal plate 1a is bent along the outer surface of the slider 2 as shown in Fig. 1cI to form the slider 1. The other end of the metal plate 1a is cut along the outer surface of the slider 2 to form the slider 2 in which the slider 1 is insert-molded.
