To provide an opening/closing body drive mechanism capable of easily determining a sensor malfunction.SOLUTION: An opening/closing body drive mechanism 1 includes an opening/closing body 2 that moves between an open position at which an opening OP provided in an installation target is opened and a closed position at which the opening OP is closed, a drive unit 3 that drives the opening/closing body 2, a detection unit 4 that detects a movement state of the opening/closing body 2, and a control unit 5 that controls a drive of the opening/closing body 2 by the drive unit 3 based on an output of the detection unit 4. The control unit 5 performs feedback control to control the drive so that a physical value detected by the detection unit 4 becomes a preset target value, and determines that the information from the detection unit 4 is abnormal if information from the detection unit 4 is different from predetermined information corresponding to the feedback control and a control value given to the drive unit 3 exceeds a predetermined threshold value.SELECTED DRAWING: Figure 1 【課題】センサについての異常を容易に判定することが可能な開閉体駆動機構を提供すること。【解決手段】開閉体駆動機構１は、取付対象に設けられた開口ＯＰを開放する開位置と開口ＯＰを閉止する閉位置との間を移動する開閉体２と、開閉体２を駆動する駆動部３と、開閉体２の移動状態を検知する検知部４と、検知部４の出力に基づいて駆動部３による開閉体２の駆動を制御する制御部５と、を備え、制御部５は、検知部４で検知した物理値が予め設定した目標値となるように駆動を制御するフィードバック制御を行い、検知部４からの情報がフィードバック制御に応じた所定の情報と異なり、且つ、駆動部３に与えられた制御値が所定の閾値を超える場合、検知部４からの情報が異常と判定する。【選択図】図１
