In the figure, a resistance element 12 is formed on the surface of a substrate 11 by means such as printing, and a sliding or moving contact (movable contact) slides and rotates on the resistance element 12.
A rotary body 14 made of an insulating material and equipped with a rotary member 13 has a circular hole 16 at its center for insertion of a protrusion 15' of a holding portion 24 of a rotary operation shaft 15, and is also provided with a thin protrusion 17. Further, a circular or non-circular hole 19 is formed so as to engage with a plurality of protrusions 18 provided on the holding portion 24 of the rotation operation shaft 15.

（発明の効果）
本発明は以上の如く構成されたものであり、種々の回転
操作軸の要望に対しても１回転繰作軸の部分だけを作れ

軸の部分だけでよいから簡単なものとなり対応が容易で
ある。(Effects of the Invention) The present invention is constructed as described above, and since it is only necessary to manufacture the one-rotation operation shaft portion to meet various requests for rotary operation shafts, it is possible to meet requests for insulated shaft types. However, the molding die is simple and easy to handle, since it requires only the almost rod-shaped rotary operating shaft part, not including the insulating rotary body part.
又、回転操作軸が変わっても絶縁性回転体は共通である
から絶縁性回転体に可動接点を取り付ける部分をあらか
じめまとめて作っておけば合理化効果も上がり、その実
用性は高い。In addition, even if the rotational operation axis changes, the insulating rotating body is the same, so if the parts for attaching the movable contacts to the insulating rotating body are made in advance, the rationalization effect will be improved, and its practicality will be high.
特性面においても、前述の如く回転操作軸の引きに対し
ては、筐体で停止し、押しに対しては、基板で停止する

るものである。In terms of characteristics, as mentioned above, when the rotary operation shaft is pulled, it stops at the casing, and when it is pushed, it stops at the board, making it easy to connect the rotary operation shaft and the insulating rotating body. Even if the variable resistor is only press-fitted, the finished variable resistor will not come off and can accommodate variations in the rotating operation shaft.
