Claims

[Claims for Utility Model Registration] 1. The operating shaft 14 of the variable resistor 12 attached to the panel chassis 10, and the shaft through hole 16 having the same cross-sectional shape as the operating shaft 14, into which the operating shaft 14 fits, are located approximately at the center. A guide member 22 is provided with a guide groove 18 having a substantially U-shaped cross section on both sides, and a protrusion 20 is provided on the inner surface of each guide groove 18. Two mating recesses 24 are provided on each side, a long hole 26 larger than the shaft hole 16 is provided approximately in the center, an engaging protrusion 28 is provided at one end, and a pressing piece 30 is provided at the other end.
a panel 38 with a circular opening 36 disposed in the same plane as the slide member 32 and having internal teeth 34 in which the engagement projection 28 engages; and an axis of the guide member 22 It includes an operating knob 40 to be attached to the tip of the operating shaft 14 passing through the through hole 16, and the sliding amount of the slide member 32 is regulated at two points by the protrusion 20 and the recess 24, and the distance between these two points is An operating knob locking device characterized in that the distance is equal to the distance between the engaging protrusion 28 and the internal toothed part 34 with which this protrusion 28 engages. 2. Instead of providing one protrusion 20 on the guide member 22 and two recesses 24 on the slide member 32, two recesses 46 are provided on the guide member 22 and one protrusion 48 is provided on the slide member 32. The operating knob locking device according to claim 1, characterized in that:
