To fix a door at a predetermined opening angle so that passengers can board a vehicle and alight from.SOLUTION: A door stay 1 is inserted into a door front end part D1 in a supported manner so that it can advance and retract horizontally, the tip part of the door stay 1 is pivotally attached to a pillar S. A gear 5 is provided rotatably near the front end part D1 in a door D and on one longitudinally lateral surface side of the door stay 1, the gear 5 being capable of engaging with a rack 1b, which is engraved in the base end of the door stay 1, from shortly before the door D is opened at a predetermined opening angle to the time when the door D is fully opened. A lever 13 is provided so as to be swayable in the front-rear direction and is biased frontward, the lever 13 having an internal tooth rack 13a that can engage with and detach from the gear 5 on its tip front part. A rotor 15 is provided on the base end side of the lever 13 and on the other longitudinally lateral surface of the door stay 1. The rotor 15 rolls on an outside cam surface 1c, which is formed in an outwardly sloping manner so that the lever 13 is angled rearward to retain the separating condition regarding the internal tooth rack 13a and the gear 5, from the state where the door D is closed to shortly before the door D is opened at the predetermined opening angle. The rotor 15 rolls to an inside cam surface 1e, which is formed inside more than the outside cam surface 1c so that the lever 13 is angled frontward to engage the internal tooth rack 13a with the gear 5, when the door D is opened at the predetermined opening angle.SELECTED DRAWING: Figure 1

    【課題】ドアを乗降者が通過可能な所定開度で固定する。【解決手段】ドア前端部D1に水平進退自在に挿通支持されたドアステー1の先端部をピラーSに枢着し、ドアD内の前端部D1近傍で、ドアステー1の長手一側面側には、その基端に刻設したラック1bに、ドアDが所定開度に開扉される直前から全開されるまでの間で噛合可能な歯車5を回転自在に設け、これに噛合・離脱可能な内歯ラック13aを先端前部に有する梃子杆13を前後揺動自在に設けて前方に付勢し、梃子杆13の基端側には、ドアステー1の長手他側面において、ドア閉扉状態から所定開度に開扉される直前までの間は、梃子杆13を後傾させて内歯ラック13aの歯車5との離間状態を保持する様に外向きに斜行形成した外側カム面1cを転動し、ドアDが所定開度に開扉した時に梃子杆13を前傾させて内歯ラック13aと歯車5を噛合させる様に外側カム面1cより内寄りに形成した内側カム面1eへ転動する転子15を設ける。【選択図】図1
