Claims

[Scope of utility model registration request]

By inserting a guide rod into the coil portion of the torsion coil spring, and providing a fixed member between the pair of leg portions and a movable member movable in the left and right directions from the neutral position, the movable member is normally kept in the neutral position. When the movable member is held in position and moved in either the left or right direction, a reaction force against the operation is generated by displacing one of the legs, wherein the movable member is in the neutral position. The coil part is configured to be displaced in the winding direction when moved from the position, and in the neutral position, a regulating part is provided for regulating the outer diameter part of the coil part from both sides. An operating device using a torsion coil spring.
