In addition, a first reflection portion 23 that reflects the light L ₀ is formed on the back surface of the operation knob 20 corresponding to the shape of the convex portion 12. The first and

second reflectors

23 and 13 may be formed substantially in parallel, but are formed non-parallel to form light when pressing the operation knob 20 as described later. The change of L ₁ is emphasized to enable more effective illumination display.

(Bezel 10)
As shown in FIG. 1A, the bezel 10 forming the outer surface supports, for example, the operation knob 20 so as to be capable of rotating and pressing, and functions as a housing for fixing the substrate 40 and the like. The bezel 10, the light guide portion 35 for guiding the light L _0, and the hole 14 which partially accommodates the operating knob 20 is formed. Further, at the lower portion, a mounting portion 18 for mounting a substrate or the like is formed. The bezel 10 may be, for example, an instrument panel or a panel constituting a center console.

The surface of the second reflective portion 13 is plated. Thus, the light L ₀ reflected by the first reflecting portion 23 of the operating knob 20, and efficiently reflected as light L ₁ can be illuminated displays the top surface 11 of the bezel 10. The surface of the second reflecting portion 13 may not be plated but may be painted or materialized.

The rotation detection element 47 detects the rotation of the operation knob 20. For example, the rotation detection element 47 is formed of a photo interrupter that detects the rotation angle of the encoder plate 48 mounted on the operation knob 20 by light irradiation and reflection detection. It is a rotary encoder.

(Operation knob 20)
The operation knob 20 is comprised from the knob 21 and the knob main body 22, as shown to FIG. 1A. The knob 21 is formed in a cylindrical shape that presses the upper surface and is gripped and rotationally operated, and the knob main body 22 is formed in a cylindrical shape on the lower side of the knob 21. The knob body 22 is accommodated in the hole 14 of the bezel 10 and the light guide 35 and is pivotally supported so as to rotate with respect to the bezel.
