PROBLEM TO BE SOLVED: To compactly install a transmitter, etc. at a lower edge side of an opening/closing body.SOLUTION: An opening/closing device includes: an opening/closing body 11 that closes so as to partition a space; a fixed seat plate 12 connected to a distal edge part of the opening/closing body 11 in a closing direction; a movable seat plate 13 opposite the fixed seat plate 12 connected to a lower edge side of the fixed seat plate 12, to be moved in an opening direction; a power generating transmission unit 50 that generates power by itself while moving in an opening direction of the fixed seat plate 12 opposite the movable seat plate 13 and wirelessly transmits a signal; and a receiving part 34 that receives the signal. The opening/closing device controls operation of the opening/closing body 11 in accordance with the signal received by the receiving part 34. The power generating transmission unit 50 has a power generating part 52, a wireless transmission circuit 53, and an antenna 54 lined up in a width direction of the opening/closing body 11 and fixed on the fixed seat plate 12, the power generating part generating power while moving in an opening direction of the movable seat plate 13 opposite the fixed seat plate 12, the wireless transmission circuit being actuated by the power generated by the power generating part 52, and the antenna sending a signal generated by the wireless transmission circuit 53 into the space.SELECTED DRAWING: Figure 1 【課題】 開閉体の下端側に送信機等をコンパクトに装着する。【解決手段】 空間を仕切るようにして閉鎖動作する開閉体本体１１と、開閉体本体１１の閉鎖方向端部に接続された固定座板１２と、固定座板１２に相対して開放方向へ移動するように固定座板１２の下端側に接続された可動座板１３と、可動座板１３に相対する固定座板１２の開放方向への移動により自己発電して信号を無線発信する発電送信ユニット５０と、前記信号を受信する受信部３４とを備え、受信部３４により受信された信号に応じて開閉体本体１１の動作を制御するようにした開閉装置において、発電送信ユニット５０は、固定座板１２に相対する可動座板１３の開放方向への移動により発電を行う発電部５２と、該発電部５２の発電電力により作動する無線送信回路５３と、無線送信回路５３により生成される信号を空間へ発信するアンテナ５４を開閉体本体１１の横幅方向へ並べて、固定座板１２に固定されている。【選択図】 図１
