PROBLEM TO BE SOLVED: To provide a rotary connector capable of stably transmitting electric power or an electric signal in a non-contact manner between a fixed side and a rotating side in a rotating element.SOLUTION: A rotary connector (1) includes: a conductive shaft (2); a bearing (3) rotatably supporting the shaft (2); and a housing (4) having the bearing (3) and an electrode part (11) at least at a position opposing to an end face of the shaft (2). The shaft (2) and the housing (4) are isolated from each other. The end face of the shaft (2) and the electrode part (11) of the housing (4) are opposed each other through an insulation fluid with higher inductivity than that of air and are capacity-coupled to transmit an AC current or an AC signal. The bearing (3) is a dynamic bearing, for example.SELECTED DRAWING: Figure 1

    【課題】回転部における固定側と回転側間において、非接触で電力や電気信号を安定して伝送することができるロータリコネクタを提供する。【解決手段】ロータリコネクタ(1)は、導電性の軸(2)と、前記軸(2)を回転自在に支持する軸受(3)と、前記軸受(3)が設置され少なくとも軸(2)の端面に対向する箇所に電極部(11)を有するハウジング(4)とを備える。軸(2)とハウジング(4)とは絶縁されている。軸(2)の端面とハウジング(4)の電極部(11)とが、空気よりも誘電率が高い絶縁性流体を介して対向し、交流電流または交流信号を伝送可能に容量結合されている。軸受(3)は、例えば動圧軸受である。【選択図】図1
