To provide a running device for a work vehicle and the work vehicle, which suppress application of a force to a main shaft member, the force which may deform the main shaft member.SOLUTION: A running device 3 of a work vehicle includes a depress device 41, a support member 45, a pair of coupling members 46, and a breaking mechanism 47. The depress device 41 includes a main shaft member 411 which elongates in a predetermined direction, and depresses a push member 412 to the main shaft member 411 toward one side in the predetermined direction. The support member 45 supports one end portion of the main shaft member 411. The pair of coupling members 46 couples the support member 45 to a fastening member 48. The breaking mechanism 47 applies, when the one coupling member 46 in the pair of coupling member 46 is broken down, a force that breaks down the other coupling member 46 to the other coupling member 46 before a force that deforms the main shaft member 411 is applied to the main shaft member 411.SELECTED DRAWING: Figure 15

    【課題】主軸部材を変形させるような力が主軸部材に加わりにくい作業車両の走行装置及び作業車両を提供する。【解決手段】作業車両の走行装置3は、押圧装置41と、支持部材45と、一対の結合部材46と、破断機構47と、を備える。押圧装置41は、所定方向に長さを有する主軸部材411を含み、主軸部材411にて所定方向の一方に押部材412を押し付ける。支持部材45は、主軸部材411の一端部を支持する。一対の結合部材46は、支持部材45を固定部材48に対して結合する。破断機構47は、一対の結合部材46の一方の結合部材46が破断すると、主軸部材411を変形させる力が主軸部材411に作用する前に他方の結合部材46を破断する力を他方の結合部材46に作用させる。【選択図】図15
