PROBLEM TO BE SOLVED: To enable a detection device to detect thin foreign objects or rod-like foreign objects.SOLUTION: A door opening/closing device of an elevator includes: a door 21; a long door sill 22 which guides the door 21 in an opening/closing direction; and a detection device which contacts a foreign object 16 when the door 21 is being closed thereby detecting the foreign object. The detection device includes a detection body 30 which is supported by the door 21 and moves in a predetermined direction when contacting the foreign object to detect the presence of the foreign object. The door sill 22 includes: a first groove part 26 where a part of the door 21 is engaged to guide the door 21 in the opening/closing direction; and a second groove part 27 where a part of the detection body is engaged so as to allow the detection body to move as the door 21 moves in the opening/closing direction.

    【課題】検出装置によって厚みの薄い異物や棒状の異物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21と、ドア21を開閉方向に案内する長尺状の敷居22と、ドア21の閉動作中に異物16に接触することにより、異物を検出可能な検出装置とを備える。検出装置は、ドア21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30を備える。敷居22は、ドア21を開閉方向に案内すべくドア21の一部が係合する第1溝部26と、ドア21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27とを備える。【選択図】図4
