For example, it is necessary to measure the nozzles generated from the plurality of rotary variable resistor bodies attached, other electrical characteristics, and the balance of the plurality of resistor bodies after assembly. And as a result of the measurement,
There may be cases where the main body of the rotary variable resistor must be replaced. However, when the rotary resistor main body is attached by caulking as in the conventional method, there is a problem in that the removal work is extremely troublesome. In addition, the metal mounting claws of the removed rotary resistor body are deformed, and if the removed rotary resistor body is to be reused, the mounting claws may need to be modified. Ta. Furthermore, if the rotary resistor main body is mounted and removed many times, the mounting claws may break, making it impossible to reuse the removed rotary resistor main body.

ら取外すことができる。[Effects of the invention] According to the invention, by simply inserting the elastic locking piece for mounting into the through-hole for installation, the locking part of the elastic locking piece for installation will engage with the edge of the through-hole for installation due to elastic engagement. It can be firmly locked against the part. In addition, by applying a force toward the case body side of the rotary variable resistor main body with fingers or a tool to the elastic locking piece for installation, the locking part of the elastic locking piece for installation is locked with the edge of the through hole for installation. Once solved, the rotary variable resistor body can be easily removed from the side wall of the box-shaped case.
