Claims

[Scope of utility model registration request]

A center conductor attached to the center of the upper surface of an insulating plate, an insulating substrate having an arc-shaped resistor attached concentrically around the outer periphery of the center conductor, and a terminal electrode provided at the end of the resistor; A lead whose one end is connected to the end of the conductor and resistor, and which is led out to the bottom surface through a through hole in the insulating substrate, and the other end has a through-hole window at the tip and is erected on the upper surface of the insulating board. a terminal, an insulating rotating body provided on its lower surface with a contact spring that bridges between the central conductor and the resistor, a hollow part that accommodates the insulating substrate and the rotating body, and a small-diameter inner wall at the bottom of the hollow part. A case is provided with a plurality of protrusions on the left and right front and rear outer surfaces of an insulating rectangular parallelepiped, and the protrusions provided on the front and rear outer surfaces of the case are fitted and filled with the through-hole windows of the lead terminals. It is fixed with an adhesive, an O-ring is inserted and pressure-welded to the upper surface of the rotating body, and the case has a U-shaped cross section with protrusions provided on the left and right outer surfaces of the case and a hook-shaped bent portion at the opening tip. A sealed variable resistor characterized by having a structure in which a top cover having spring properties is fitted.
