ABSTRACT:
A variable resistor includes a reduction rotation transmission mechanism including a plurality of gears for transmitting rotation of an operating member, a resistance member including a rotary member for varying resistance, and a rotation transmission member for rotating the rotary member. A plate-shaped clutch is disposed between the rotation transmission member and a geared wheel disposed at a termination end of the reduction rotation transmission mechanism, so that a clutch mechanism is formed. The transmission of the rotation of the rotation transmission member is performed and the rotation of the rotation transmission member is stopped by the clutch mechanism.
