Abstract: A variable electronic component includes an insulating substrate and a metal rotor rotatably attached to the upper surface of the substrate. The rotor includes a cup-shaped member attached to the substrate and having an upper end formed with an outward flange. The rotor also includes a plate member formed integral with the flange via a hinge portion. The plate member is arranged on an upper side or a lower side of the flange. The cup-shaped member or the plate member is formed with a recess, and the other is formed with a protrusion fitted into the recess.

Abstract: The invention relates to a variable electronic component that can adjust an electrical characteristic such as a resistance value, preferably applicable to a chip-type variable resistor. The chip-type variable resistor includes an insulating substrate 1 and a rotor 5 rotatably mounted on the upper face of the insulating substrate 1. The rotor 5 includes a cup-shaped member 6 and a ring-shaped sliding member 7 integrally connected via a hinge portion 8 and is rotatably mounted to the upper surface of the insulating substrate by calking. The flange of the cup-shaped member includes a movable stopper projecting downward, and the insulating substrate 1 includes an upwardly open groove 16 that allows the movable stopper 15 to rotate. End portions 16a of the upwardly open groove 16 are intruding into an inner region of the insulating substrate 1 from the side face thereof.
