To provide a technique of miniaturizing a chassis device using a rocker bogie mechanism.SOLUTION: A chassis device includes: a driving wheel 24; a first driven wheel 26 disposed on one side in a longitudinal direction with respect to the driving wheel 24; a second driven wheel 28 disposed on the other side in the longitudinal direction with respect to the driving wheel 24; a bogie link member 38 supporting the driving wheel 24 and the first driven wheel 26 to be rocked around a first rocking shaft 44; and a rocker link member 40 supporting the second driven wheel 28 and the bogie link member 38 to be rocked around a second rocking shaft 50. The first rocking shaft 44 is positioned vertically above a rotation shaft 70 rather than on the same vertical line as the rotation shaft 70 of the driving wheel 24 and positioned inside an outer shape of the driving wheel 24 when seen from a right-left direction.SELECTED DRAWING: Figure 3

    【課題】ロッカーボギー機構を用いた足回り装置の小型化を図る技術を提供することにある。【解決手段】駆動輪24と、駆動輪24に対して前後方向一方側に配置される第1従動輪26と、駆動輪24に対して前後方向他方側に配置される第2従動輪28と、駆動輪24及び第1従動輪26を支持し第1揺動軸44周りに揺動可能なボギーリンク部材38と、第2従動輪28及びボギーリンク部材38を支持し第2揺動軸50周りに揺動可能なロッカーリンク部材40と、を備え、左右方向から見て、第1揺動軸44は、駆動輪24の回転軸70と同一鉛直線上になく、回転軸70より鉛直方向上方に位置し、駆動輪24の外形の内側に位置する足回り装置。【選択図】図3
