PROBLEM TO BE SOLVED: To provide a rotary body for power transmission of an electric field coupling type which can be a simpler shaft structure as compared with prior art and easily used by users.SOLUTION: A rotary body for power transmission of an electric field coupling type comprises a rotor rotating around a predetermined axis and a stator. One present inside, between the rotor and the stator, is composed of a shaft body, a first isolation layer, and a first electrode laminated sequentially from the center of the axis. The other one present outside is composed of a second electrode paired with the first electrode to form a junction capacitance, a second isolation layer, and an enclosure laminated sequentially from the center of the axis. One of the first electrode and the second electrode is divided by a division number of 2 or above and connected with an AC power source. The other one is divided by a division number more than the division number and connected with a load via a controller controlling a current flow. Isolating layers are formed on mutually opposed electrode surfaces of the first electrode and the second electrode. The electrode surfaces slide either in contact with each other or with a fluid layer sandwiched therebetween.SELECTED DRAWING: Figure 9 【課題】従来と比較して軸構造を単純化でき、ユーザが容易に活用できる、電界結合方式の電力電送回転体を実現化すること。【解決手段】電界結合方式の電力伝送回転体は、所定の軸を中心に回転する回転体と、固定体とを備える。回転体と固定体のうち内部に存在する一方は、軸の中心から順番に、軸体と、第１絶縁層と、第１電極とを積層して構成される。外部に存在する他方は、軸の中心から順番に、第１電極と対になり接合容量を形成する第２電極と、２絶縁層と、外囲体とを積層して構成される。第１電極と第２電極のうち、一方は２以上の分割数で分割されて交流電源が接続され、他方は分割数よりも細かく分割されると共に電流の流れを制御する制御部を介して負荷が接続される。第１電極と第２電極の相互に対向する電極表面には絶縁層が形成されて接触して摺動するか又は流体層が挟まれて摺動する。【選択図】図９
