変抵抗器。[Claims for Utility Model Registration] A housing, an operating shaft inserted from the side of the housing, a rotor installed into the housing, and a slider or an elastic body mounted on the rotor. the rotor has a groove that engages with a protrusion in the housing to define a rotation range; The worm is arranged so as to mesh with the provided worm, and when the rotor is rotated via the worm and the bevel gear by rotation of the operating shaft, a variable resistance is formed between the resistance elements of the resistance board, and the When the tips of the teeth of the worm pass over the teeth of the bevel gear at both ends of the rotation range of the rotor, the clutch mechanism is configured to restore and maintain the meshing between the worm and the bevel gear by the slider or elastic body. A screw-type variable resistor characterized by the following:
