PROBLEM TO BE SOLVED: To provide a rotary connector by which the number of components concerning optical communication are reduced, thereby enabling simplification of a device configuration.SOLUTION: A rotary connector 1 comprises an optical communication part 25 which can perform optical communication between a stationary body 8 and a rotary body 9, and an electric wave communication part 30 which can perform communication between the stationary body 8 and the rotary body 9 by electric wave of a UHF band and so on. When a rotational angle of a steering wheel 3a is at a neutral position or near the neutral position, the optical communication part 25 is selected for communication between the stationary body 8 and the rotary body 9. When the rotational angle of the steering wheel 3a is not at the neutral position or not near the neutral position, the electric wave communication part 30 is selected for communication between the stationary body 8 and the rotary body 9.SELECTED DRAWING: Figure 1
【課題】光通信に係る部品を減らして装置構成を簡素化することができる回転コネクタを提供する。【解決手段】回転コネクタ1は、固定体8及び回動体9の間で光通信が可能な光通信部25と、固定体8及び回動体9の間でUHF帯などの電波によって通信が可能な電波通信部30とを備える。ステアリングホイール3aの回転角が中立位置又はその付近のときには、固定体8及び回動体9の通信に光通信部25が選択される。ステアリングホイール3aの回転角が中立位置又はその付近ではないときには、固定体8及び回動体9の通信に電波通信部30が選択される。【選択図】図1
