Abstract
An operating knob including a first illumination portion with an annular shape and a second illumination portion, is provided around the operating knob. The operating knob is configured by a combination of an inner shaft body made of a resin and a grip ring body, allowing the inner shaft body to be fitted outward. A light shielding cap is attached to a front end portion of the inner shaft body. A cylindrical light guide portion having the first illumination portion in the front end face and a drive portion to be connected to a rotating shaft are integrally molded in the inner shaft body, and a rear end face of the cylindrical light guide portion opposes a first light emitting face. A light incident face opposes a light source and the first and second illumination portions and are illuminated by light of the light source via the light guide member.
