PROBLEM TO BE SOLVED: To provide a pinching detector that comprises a small number of components.SOLUTION: A power window 1 includes: an electrode 4 for a sensor, which is provided in window glass 2; an electrode 7 for positional detection, which increases an area facing the electrode 4 for the sensor, in association with the ascent of the window glass 2; and a control part 5 which detects that something is pinched between the window glass 2 and the window frame, through a change in electrostatic capacity of the electrode 4 for the sensor, and which detects a position of the window glass 2 through the change of the electrostatic capacity.SELECTED DRAWING: Figure 1
【課題】構成要素の少ない挟み込み検出装置を提供する。【解決手段】パワーウインド1は、窓ガラス2に設けられるセンサ用電極4と、窓ガラス2の上昇に伴いセンサ用電極4との対向面積が増加する位置検出用電極7と、センサ用電極4における静電容量の変化を通じて窓ガラス2と窓枠との間の挟み込みを検出するとともに、静電容量の変化を通じて窓ガラス2の位置を検出する制御部5とを備える。【選択図】図1
