Patent ID: 7015788

Claim:
A variable electronic component, comprising an insulating substrate having an upper surface formed with a resistive layer, and a metal rotor rotatably attached to the upper surface of the substrate, wherein the rotor includes a cup-shaped member attached to the substrate and having an upper end formed with an outward flange, the rotor also including a plate member formed integral with the flange via a hinge portion, the rotor further including a contact member disposed at a position opposite to the hinge portion and held in sliding contact with the resistive lever, the cup-shaped member being open upward, the plate member being arranged on an upper side or a lower side of the flange, wherein one of the cup-shaped member and the plate member is formed with a recess, the other of the cup-shaped member and the plate member being formed with a protrusion fitted into the recess, the recess being depressed in a thicknesswise direction of the plate member and disposed between the hinge portion and the contact member, the protrusion projecting in the thicknesswise direction of the plate member and being disposed between the hinge portion and the contact member.
