PROBLEM TO BE SOLVED: To provide a door position detector capable of improving reliability while detecting a door position with high accuracy.SOLUTION: A door position detector D comprises: a first fixed electrode 11 and a second fixed electrode 12 provided on a case 82; and a moving electrode 20 provided in a movable portion of a door 82 that is an end portion 81a1 facing the case 82 at a predetermined distance therebetween. Furthermore, a first capacitor portion C1 constituted by the first fixed electrode 11 and the moving electrode 20 and a second capacitor portion C2 constituted by the second fixed electrode and the moving electrode 20 are configured so that electrostatic capacitances change in response to rotation of the door 81, and the door position detector D detects a position of the door 81 on the basis of the electrostatic capacitances of the first capacitor portion C1 and the second capacitor portion C2.SELECTED DRAWING: Figure 1

    【課題】高精度でドアの位置を検出しながらも、信頼性の向上を図ることが可能なドア位置検出装置を提供すること。【解決手段】ドア位置検出装置Dは、ケース82に設けられる第1固定電極11及び第2固定電極12と、ドア81の移動可能な部分で且つケース82と所定間隔を隔てて対向する端部81a1に設けられる移動電極20と、を有しており、更に、第1固定電極11と移動電極20とで構成される第1コンデンサ部C1と、第2固定電極12と移動電極20とで構成される第2コンデンサ部C2は、ドア81の回動に伴って静電容量が変化するように構成され、第1コンデンサ部C1及び第2コンデンサ部C2の静電容量に基づいてドア81の位置を検出する。【選択図】図1
