ABSTRACT:
In a rotary electric component, an annular thin faceplate disposed around a rotary knob is provided with an illuminated display portion inner and outer circumferential portions of the rear surface of the faceplate are bonded and fixed to a holder, and the rotary knob and the display portion is assembled in cutout of a front panel. A large-diameter annular portion of the holder adhering to the outer circumferential portion of the faceplate protrudes forward farther than a small-diameter annular portion adhering to the inner circumferential portion. A protruding portion of the front panel extending around the circumferential edge of the cutout presses a region near the outer circumferential portion of the faceplate. As a result, the inner circumferential portion of the faceplate is reliably compressed against the holder a small-diameter annular portion).
