PROBLEM TO BE SOLVED: To provide a door closing force checking device capable of preventing falling of a tool on a hoistway during the checking work of a door closing force.SOLUTION: A door closing force checking device configured to check the closing force of a door provided in an elevator device includes: a coil spring 13 displaced according to the closing force; an inner cylinder 14 and an outer cylinder 15 storing the coil spring 13 and slidable to each other; a fixture 10 having a first display part 20 and a second display part formed in the inner cylinder 14 and corresponding to the permissible value of a displacement amount relative to the outer cylinder 15; a fixed part disposed in a predetermined part, e.g., a magnet 11; and a connector for connecting the magnet 11 and the fixture 10, e.g., a string-like body 12. The door includes a landing door 1 forming a smoke blocking door, and the coil spring 13 includes a spring having one end 13a locked to the inner cylinder 14 and the other end 13b locked to the outer cylinder 15.SELECTED DRAWING: Figure 1

    【課題】ドアの閉じ力の確認作業に際して、昇降路への治具の落下を防ぐことができるドアの閉じ力確認装置の提供。【解決手段】本発明に係るドアの閉じ力確認装置は、エレベータ装置に備えられるドアの閉じ力を確認するものであって、閉じ力に応じて変位するコイルスプリング13と、このコイルスプリング13が収納され、互いに摺動自在な内筒14及び外筒15とを有し、内筒14に、外筒15との間の相対的な変位量の許容値に相応する第1表示部20及び第2表示部が形成された治具10と、所定部位に配置される固定部、例えば磁石11と、この磁石11と治具10を連結する連結体、例えば紐状体12とを備えている。ドアは、遮煙ドアを形成する乗場ドア1から成り、コイルスプリング13は、一端13aが内筒14に係止され、他端13bが外筒15に係止されたものから成っている。【選択図】図1
