PROBLEM TO BE SOLVED: To provide a door opening/closing device of an elevator, simply structured, which can detect contact of a foreign matter in a direction orthogonal to a door opening/closing direction without increasing the number of components.SOLUTION: The door opening/closing device of an elevator comprises: a door; a long door sill that guides the door in an opening/closing direction; and a detecting device that can detect a foreign matter by contacting the foreign matter during closing movement of the door. The detecting device comprises a detecting body that is supported on the door and moved in a predetermined direction when contacting the foreign matter so as to detect the presence of the foreign matter. The door sill comprises a first groove part with which a part of the door is engaged in order to guide the door in the opening/closing direction and a second groove part with which a part of the detecting body is engaged so that the detecting body can move accompanying the movement in the opening/closing direction of the door. The second groove part comprises a guiding part that guides the detecting body upward when force along a direction orthogonal to the opening/closing direction of the door acts on the detecting body during the closing movement of the door.
【課題】 構造が簡単で、部品数を増大させることなく、ドアの開閉方向に直交する方向における異物の接触を検出できるようにする。【解決手段】 エレベータのドア開閉装置は、ドアと、ドアを開閉方向に案内する長尺状の敷居と、ドアの閉動作中に異物に接触することにより当該異物を検出可能な検出装置とを備える。検出装置は、ドアに支持されるとともに、異物に接触したときに所定の方向に移動することにより、異物の存在を検出する検出体を備える。敷居は、ドアを開閉方向に案内すべくドアの一部が係合する第1溝部と、ドアの開閉方向の移動に伴って検出体が移動できるように、検出体の一部が係合する第2溝部とを備える。第2溝部は、ドアの閉動作中に、ドアの開閉方向に対して直交する方向に沿う力が検出体に作用したときに、検出体を上方に案内する案内部を備える。【選択図】 図4
