PROBLEM TO BE SOLVED: To provide an opening holding mechanism which can easily hold a door at a partially opened position only by opening the door of the closed state.SOLUTION: An opening holding mechanism is equipped with an arm 20 of which one end is so connected to a pivot 32 of an inner door end of a door 10 as to be horizontally rotatable, and the other end has a hook part 21 which vertically projects. A door frame 23 of a work machine is provided with an arm holding part 24. The hook part 21 of the arm 20, which is rotated to a position contacting with a regulation part 25 in the closed state of the door 10, is guided by a guide face 27 when the door 10 is moved to a partially opened position and is moved to a holding hole 26, and thus, the hook part 21 is connected to the arm holding part 24.SELECTED DRAWING: Figure 2
【課題】 閉状態のドアを開くだけで容易に部分的に開いた位置に保持することができる開放保持機構を提供する。【解決手段】 一端がドア１０の内側の戸先の枢軸３２に水平回動可能に連結され他端に上下に突出した引掛部２１を有するアーム２０を備えている。作業機械のドアフレーム２３にはアーム保持部２４が設けられている。ドア１０の閉状態で規制部２５に接する位置まで回動させたアーム２０の引掛部２１は、ドア１０を部分的に開いた位置に移行する際に案内面２７に案内されることにより保持穴２６に移動し、アーム保持部２４と連結する。【選択図】 図２
