To reduce shock when a vehicle runs through a bad road.SOLUTION: A running device includes: a track frame placed at a side portion of a vehicle body frame; a first arm member attached to the track frame in such a way that a front end and a rear end are alternately swingable in the vertical direction; a first lower turn wheel attached to the front end of the first arm member so as to be freely turnable; a rear end idler attached to the rear end of the first arm member so as to be freely rotatable; a plurality of running wheels provided at the front side of the track frame and the rear side thereof; and a crawler tensioned around the first lower turn wheel, the rear end idler and the plurality of running wheels. In a side view, a rear-side inter-center distance between the swing center of the first arm member and the rotation center of the rear end idler is longer than a front-side inter-center distance between the swing center of the first arm member and the turn center of the first lower turn wheel.SELECTED DRAWING: Figure 3

    【課題】悪路走行時の衝撃を低減する。【解決手段】走行装置は、車体フレームの側部に配置されたトラックフレームと、前端部及び後端部が交互に上下に揺動可能なように前記トラックフレームに取り付けられた第1アーム部材と、前記第1アーム部材の前記前端部に回転自在に取り付けられた第1下転輪と、前記第1アーム部材の前記後端部に回転自在に取り付けられた後端アイドラと、前記トラックフレームの前後に設けられた複数の走行輪と、前記第1下転輪、前記後端アイドラ及び前記複数の走行輪の周囲に巻回された履帯と、を備え、側面視で、前記第1アーム部材の揺動中心と前記後端アイドラの回転中心と間の後側中心間距離は、前記第1アーム部材の前記揺動中心と前記第1下転輪の回転中心との間の前側中心間距離よりも長い。【選択図】図3
