PROBLEM TO BE SOLVED: To provide a rotary operation device allowing a display window to be formed at the center part of an operation member of the rotary operation device. SOLUTION: The operation member 11 is composed of a ring 12 disposed on a surface of a case 14, a first annular rotating plate 16 integrally rotating with the ring 12, and a second annular rotating plate 18 positioned inside the case 14 and integrally rotating with the rotating plate 16. When the ring 12 is rotated, the rotating plate 16 rotates, and an engaging claw 20 engages with an engaging part 1408 of a hole 1402 of the case 14 to provide click feeling. When the ring 12 is rotated, the second rotating plate 18 rotates, and after the engaging claws 20 engage with a certain engaging part 1408 and before they engage with the next engaging part 1408, an operation piece 2302 of a seesaw switch 32 is once pushed down by one projection part 1804 and returned to a neutral position. |
