To suppress a driving wheel from idling or skidding due to an instantaneous impact force that a coupled driving wheel receives at a moment of collision when the coupled driving wheel collides with a bump or a protruding part.SOLUTION: A running gear 100 comprises a rocker-bogie linking mechanism in which a bogie linking member 110 for supporting a driving shaft 108a of a driving wheel 108 and a rotating shaft 109a of a first coupled driving wheel 109 is connected to a rocker linking member 111 for supporting a rotating shaft 107a of a second coupled driving wheel 107 situated opposite to the first coupled driving wheel to the driving wheel swingably around a given rocker-shaft 113. The rocker-shaft is arranged at the same height as or on a lower position than that of the rotating shaft of the driving wheel.SELECTED DRAWING: Figure 1
【課題】一方の従動輪が段差や凸部に衝突した瞬間に当該一方の従動輪が受ける瞬間的な衝撃力によって駆動輪が空回りあるいはスリップすることを抑制する。【解決手段】駆動輪108の駆動軸108aと第一従動輪109の回転軸109aとを支持するボギーリンク部材110と、駆動輪に対して第一従動輪の反対側に位置する第二従動輪107の回転軸107aを支持するロッカーリンク部材111とを、所定の揺動軸113回りで揺動可能に接続したロッカーボギーリンク機構を備える走行装置100であって、前記揺動軸は、前記駆動輪の回転軸と同じ高さ又はこれよりも低い位置に設けられている。【選択図】図1
