To achieve high runnability and workability.SOLUTION: A crawler travel device includes: a first wheel; a second wheel arranged being spaced from the first wheel; a support frame for supporting the first wheel and the second wheel; a third wheel arranged above the support frame; an endless crawler wound onto the first wheel, the second wheel and the third wheel; and a vehicle height change mechanism for changing a position of the support frame in a perpendicular direction relative to the third wheel. The vehicle height change mechanism includes an actuator which is shrinkable in the perpendicular direction and changes a position of the support frame in the perpendicular direction relative to the third wheel.SELECTED DRAWING: Figure 1

    【課題】走行性・作業性を向上させる。【解決手段】クローラ走行装置は、第1車輪と、第1車輪と離間して配置された第2車輪と、第1車輪と第2車輪とを支持する支持フレームと、支持フレームの上方に配置された第3車輪と、第1車輪、第2車輪、及び第3車輪に巻き掛けられた無端状のクローラと、第3車輪に対する支持フレームの鉛直方向の位置を変更する車高変更機構と、を備えている。また、車高変更機構は、鉛直方向に収縮可能であり、第3車輪に対する支持フレームの鉛直方向の位置を変更するアクチュエータを有している。【選択図】図1
