PROBLEM TO BE SOLVED: To provide a door opening travel arrester which does not require components to be installed onto a guide rail, and can suppress an impact given to a car even if the car travels in the door-opened state, and of which an occupied space can be reduced.SOLUTION: A door opening travel arrester according to the present invention is provided on an elevator which is equipped with a car 2 vertically elevating in a hoistway 1, and a guide part 5 having a slidable material 4 which is provided upright in the hoistway 1 and slidably contacts the guide rail 3. The arrester includes a brake part which contacts the guide rail 3 and brakes the car 2, and is so configured tat the brake part 6 is provided on the guide part 5. The brake part 6 has a contact part 7 which projects from a surface 4a of the slidable material 4 of the guide part 5 during each floor stop of the car 2 and contacts a rail part 3a of the guide rail 3.

    【課題】ガイドレールへの設置部品を要することなく、また、乗かごが戸を開いた状態で走行した際にも、乗かごに与える衝撃を抑えることができ、また、占有スペースを小さくすることができる戸開走行防止装置の提供。【解決手段】本発明に係る戸開走行防止装置は、昇降路1内を上下方向に走行する乗かご2と、昇降路1内に立設され、ガイドレール3に摺接する摺動材4を有するガイド部5とを備えたエレベータに設けられ、ガイドレール3に当接して乗かご2を制動する制動部を備え、この制動部6をガイド部5に設けた構成にしてある。制動部5は、乗かご2の各階停止中にガイド部5の摺動材4の表面4aから突出し、ガイドレール3のレール部3aに当接する当接部7を有している。【選択図】図4
