PROBLEM TO BE SOLVED: To provide an input device with an illumination function which can illuminate an annular illumination part provided on an operation member which can be rotated and a plurality of illumination parts with the same light source.SOLUTION: An operation knob 2 which can be rotated includes an annular first illumination part 20. Second illumination parts 30 are provided around the operation knob 2. The operation knob 2 is constituted by combining a resin inner shaft body 6 and a holding ring body 7 externally fitted to the inner shaft body 6, and a light shielding cap 8 is attached to a front end part of the inner shaft body 6. In the inner shaft body 6, a cylindrical light guide part 6a having the first illumination part 20 on the front end surface and a drive part 6b connected to a rotary shaft part 10a of a rotary encoder 10 are integrally molded, and a rear end surface 6g of the cylindrical light guide part 6a faces a light emitting surface 5c of a light guide member 5 over the whole circumference. A light-incident surface 5d of the light guide member 5 faces a light source 4, and the first and second illumination parts 20, 30 are illuminated with light from the light source 4 through the light guide member 5. |
