PROBLEM TO BE SOLVED: To provide a running vehicle which stably runs and enables improvement of the running performance on an irregular ground where slopes and irregularities exist.SOLUTION: A running vehicle 1 includes: a vehicle body frame 10; at least a pair of left and right running gears 30; and a suspension device 50 which suspends the pair of left and right running gears 30 on the vehicle body frame 10. The suspension device 50 comprises: a bogie frame 51 which is supported on the vehicle body frame 10 so as to rotate with a vertically arranged steering shaft 53 set as an axis; a pair of left and right connection mechanisms 52 which connect the pair of left and right running gears 30 at left and right sides of the bogie frame 51 so as to enable the pair of left and right running devices 30 to respectively move up and down in a steering shaft 53 direction; and a lifting device 400 which moves up and down the running gears 30.
【課題】傾斜地や凹凸のある不整地において、安定して走行できるとともに走行性が向上した走行車両を提供する。【解決手段】車体フレーム10と、少なくとも左右一対の走行装置30と、左右一対の走行装置30を車体フレーム10に懸架する懸架装置50とを備える走行車両1において、懸架装置50は、車体フレーム10に上下方向の操舵軸53を軸として回動自在に支持されるボギーフレーム51と、ボギーフレーム51の左右において左右一対の走行装置30をそれぞれ操舵軸53方向に昇降可能に連結する左右一対の連結機構52と、走行装置30を昇降する昇降装置400とからなる。【選択図】図9
