Claims

[Scope of utility model registration request]

A rotation operation shaft that drives the valve device, a rotation restriction plate that is slidably fitted onto the operation shaft and whose rotation range is restricted to a minute angle by a fixed portion, and a rotation restriction plate that engages with and disengages from the rotation restriction plate. A rotating body that is fitted onto the rotating operation shaft in a pairwise manner, a pair of protruding pieces that protrude on the diameter line of the outer periphery of the rotating body, and a pair of protruding pieces that coincide with the protruding pieces at a second stop position of the operating shaft. a pair of cam recesses provided in the fixed cylindrical portion, and a spring that biases the rotating body in a direction away from the rotation regulating plate;
a spring that is biased in a direction away from the rotating body; a pair of first rods that protrude from the surface of the rotation regulating plate facing the rotating body, and that the protruding pieces abut at both ends of the rotational range of the rotating body; and third
It consists of a stopper and a second stopper located between the first and third stoppers and whose width in the circumferential direction is appropriately set, and between the first stopper and the third stopper of the rotation regulating plate. The sum of the rotation range of the rotation plate of the rotation body and the rotation restriction plate is set to match the rotation range of the rotation operation shaft from the first stop position to the third stop position, and An operating device for a three-position switching valve device, in which a second stopper of a movement restriction plate is opposed to a cam recess of a fixed part, and a rotating body is inserted between the rotation restriction plate and a fixed part provided with a cam recess.
