Claims

[Claims for Utility Model Registration] 1. An operating shaft 14 of a variable resistor 12 attached to a panel chassis 10, and a shaft through hole 16 having the same cross-sectional shape as the operating shaft 14 into which the operating shaft 14 fits. a first gear 18; a second gear 22 with a through hole 20 that meshes with the first gear 18; a locking screw 24 inserted through the through hole 20 of the second gear 22; Female threaded portion 26 into which the screw 24 is threaded
a holding member 34 having one end vertically connected to the fixing member 30 and having an opening 32 at the other end through which the operating shaft 14 is inserted; An operation for attaching the protrusion 28 at the other end of the fixing member 30 to the tip of the operating shaft 14 that passes through the small hole 36 provided in the panel chassis 10 and the shaft through hole 16 of the first gear 18. A common opening 40 is disposed between the knob 38, the first gear 18, the second gear 22, and the operating knob 38, through which the operating shaft 14 passes, and for operating the locking screw 24. A locking device for an operating knob, characterized in that it includes a panel 42 with a panel 42 provided therein. 2. The operating shaft 14 penetrates the panel 42, and
Common opening 4 for operating the locking screw 24
2. The operating knob according to claim 1, wherein instead of providing the opening 40a through which the operating shaft 14 passes and a small opening 41a for operating the locking screw 24a, the panel 42 is provided with separate openings 40a through which the operating shaft 14 passes and a small opening 41a for operating the locking screw 24a. locking device.
