To provide a link door holding structure capable of making a door lock structure simple and inexpensive while securing door holding performance.SOLUTION: A link door holding structure includes a cab frame, an entrance formed on its side surface, a door 5, a link mechanism 6 for supporting the door 5 so as to open obliquely forward from a fully closed position, a door lock device provided at the rear part of the door 5 and locking a movement of the door 5 in the horizontal direction, a striker provided at the front part of the door 5, and a holder 9 fixed to the cab frame and fitted with the striker when the door 5 is closed. The holder 9 is formed in a forked opening shape and has an opening directed obliquely forward, and the link mechanism 6 moves the door lock device in the direction of a predetermined large angle with respect to the longitudinal direction just before the fully closed position when closing the door 5 and moves the striker in the oblique direction of a predetermined small angle with respect to the longitudinal direction.SELECTED DRAWING: Figure 7

    【課題】ドアの保持性能を確保しつつドアロックの構造を簡易かつ安価にできるリンクドア保持構造を提供する。【解決手段】リンクドア保持構造は、キャブフレームと、その側面に形成された乗降口と、ドア5と、ドア5を全閉位置から斜め前方に開くように支持するリンク機構6と、ドア5の後部に設けられドア5の左右方向の移動をロックするドアロック装置と、ドア5の前部に設けられたストライカーと、キャブフレームに対して固定されドア5が閉じるときストライカーと嵌合されるホルダー9とを備え、ホルダー9は、二股に開く形状に形成されると共に、斜め前方に向かう開口を有し、リンク機構6は、ドア5を閉じるとき全閉位置の直前でドアロック装置を前後方向に対して大きい所定角度の方向に移動させると共に、ストライカーを前後方向に対して小さい所定角度の斜め方向に移動させる。【選択図】図7
