Claims

[Scope of utility model registration request]

It has a rotation operation part and has a variable rotation angle of 360 degrees.
A variable electrical component, such as a variable resistor, is connected to a rotary operating section of the variable electrical component and rotates together with the operating section, and teeth are formed on the circumferential surface according to the rotation angle of the variable electrical component. A main body gear is formed with a display section that displays the number of rotations on the top surface, a drive gear that decelerates the rotation of the operating section to be rotated and drives the main body gear to rotate, and a main body gear that is supported at one end and whose other end is the main gear. The control spring is brought into contact with the peripheral surface of the main body gear, and the teeth of the drive gear mesh with the teeth adjacent to the portion of the main body gear where no teeth are formed. A rotation operating device for a variable electrical component, comprising a protrusion formed on the circumferential surface of a main gear so as to rotate the main gear in a direction opposite to the applied rotation direction.
