６は刷子摺動部である。Conventional configuration and problems thereof Conventionally, a variable resistor that obtains a stepped output without being in an open state has been configured as shown in FIGS. 1 and 2. That is, a large number of conductive parts 1 having a hook-shaped pattern are combined and provided on an insulating substrate (not shown), each conductor part 1 is connected to a resistor part 2, and the upper conductor part 1 is connected in the sliding direction. By sliding a brush (not shown) having a width in the vertical direction, one of the terminal attachment parts 3 and 4 at both ends of the resistor part 2 and the circular part are electrically bridged with the brush. This is a configuration in which a stepped output is obtained between the terminal mounting portion 5 and the terminal mounting portion 5.
6 is a brush sliding part.

れの余裕があまりないという問題があつた。 However, with such a configuration, as the brush becomes smaller, the effect of misalignment in the direction perpendicular to the sliding direction of the brush increases, and if the width of the brush shifts to the position X in Figure 1, the brush becomes open. It is.
Now, in FIG. 2, if the width of the brush is a, the interval between the key-shaped patterns of the conductor part 1 is b, and the minimum bulk of the brush and the conductor part 1 to maintain continuity is α, then
The brush position deviation margin A 1 is A 1 =(ab)/2-α. Then, when the brush position B in the state of no misalignment deviates beyond the brush position C in the limit misalignment state, it becomes an open state, and there is a problem that there is not much margin for misalignment of the brush.

例と同じである。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be explained below with reference to FIGS. 3 and 4.
The explanation will be given with the same numbers attached to the same parts as above along with the drawings. In the present invention, a large number of conductor portions 7 having concave patterns 7a and convex patterns 7b are provided on an insulating substrate (not shown) in such a way that adjacent concave and convex portions engage with each other, and the rest is as described above. This is the same as the conventional example.
本考案の導体部７における凸形パターン７ｂの
巾ｅは、
ｅ＝ａ−2b−2α

となり、これは従来例のA1＝（ａ−ｂ）２−αの
２倍となる。よつて本考案により刷子位置ずれに
対する余裕は従来例の２倍となるのである。 The width e of the convex pattern 7b in the conductor portion 7 of the present invention is e=a-2b-2α, and the brush misalignment margin A2 is A2 =(a+e)/2-α=a-b-2α. , which is twice the conventional value A 1 =(a-b)2-α. Therefore, with the present invention, the margin against brush position deviation is twice as large as that of the conventional example.
