PROBLEM TO BE SOLVED: To make it possible to arrange a rotational operation body having a structure for detecting an amount of rotation with rotation of a follower gear, and a pushing operation body transparently illuminated, close to each other.SOLUTION: An operation device including a dial 10 operated by being pushed by a user and transparently illuminated, and a knob 20 operated by being rotated by a user comprises: a main motion gear 30 rotated by the rotating operation force of the dial 10; a follower gear 40 rotated by engaging the main motion gear 30 and rotated by an encoder 50 in terms of an amount of rotation; a reflector 72 configured to reflect light emitted from a light source 80 and guiding it to the incident face 21a of the knob 20; and a partition plate 71 formed from resin integrally with the reflector 72, having a through-hole 71a into which the rotation shaft part 42 of the follower gear 40 is inserted, and separating the encoder 50 side and the main motion gear 30 side. By forming the through-hole 71a larger than the follower gear part 41, the follower gear part 41 can be inserted into the through-hole 71a from the encoder 50 side. |
