PROBLEM TO BE SOLVED: To provide a tie down device which is quickly arrested by a tie down rail while a strength of a lower part of a housing being increased, and an elevator equipped with the tie down device.SOLUTION: A tie dowm device comprises a housing 8c which is so guided along a tie down rail 8a as to be vertically movable and has inclined surfaces 8b which face each other with a guide part 8i of the tie down rail 8a interposed therebetween and are divergently opened upwards in a direction of separating from the guide part 8i, and a wedge 8d which is located between the guide part 8i and the inclined surface 8b and can be frictionally engaged with the guide part 8i, and further comprises an elastic body 8i which elastically energizes the wedge 8d by pressing the wedge 8d from above.SELECTED DRAWING: Figure 4
【課題】筐体下部の強度を向上させつつ、素早くタイダウンレールに拘束されるタイダウン装置およびタイダウン装置を備えるエレベータの提供。【解決手段】タイダウンレール8aに沿って上下動可能に案内され、タイダウンレール8aの案内部8iを挟んで対向しつつ、上方に向かって案内部8iから離れる方向へ末広がりに開いている傾斜面8bを有する筐体8cと、案内部8iと傾斜面8bとの間に配置され、案内部8iと摩擦係合可能なウェッジ8dとを備え、さらに、ウェッジ8dを上方から押さえつけることで、ウェッジ8dを下方に弾性付勢するための弾性体8iを備える。【選択図】図4
