ABSTRACT:
A variable resistor device with a lock mechanism in which a push on the operating rod thereof causes it to be locked in its inserted state and another push causes it to restore to its original position. According to the present invention, even if a plurality of such devices are mounted on one operating panel with the operating rods crowdedly projecting, there is substantially no possibility that the user inadvertently manipulates two or three adjacent rods at a time. Further the push stroke of the operating rod can be optionally set with ease, and even if the push stroke is set large, the overall length of the device can be made small.
