PROBLEM TO BE SOLVED: To make it possible to achieve easy disassembly work for a trank roller around which a travel crawler is wound in a crawler travel device of a work vehicle.SOLUTION: In a travel device of a work vehicle in which a travel crawler (22) is wound around a front side drive wheel (18) pivoted to a travelling transmission case and plural follower wheels (19, 21, 25) suspended and supported by a travel chassis (1), a first opening hole (21c) for insertion of a roller wheel shaft (27) on one of left and right sides and a second opening hole (21d) for insertion of a tool on the other side of left and right sides are communicated with each other thereby forming a shaft hole (21b) in the follower wheels (19, 21, 25). The follower wheels (19, 21, 25) are rotatably suspended and supported to a ring body shaft (27), which is inserted into the shaft hole (21b) from the first opening hole (21c), via a bearing (28), and the second opening hole (21d) is closed by a lid body (34) via the bearing (28).
【課題】作業車両のクローラ走行装置において、走行クローラを巻き架ける転輪の分解作業を容易にする。【解決手段】走行ミッションケースに軸架している前側の駆動輪(18)と、走行車台(1)に支架されている複数の従動輪体(19,21,25)とに走行クローラ(22)を巻回してある作業車両の走行装置において、従動輪(19,21,25)には、左右一側の転輪軸(27)挿通用の第1開口穴(21c)と、左右他側の工具挿入用の第2開口穴(21d)とを連通させて軸穴(21b)を形成し、従動輪(19,21,25)を、第1開口穴(21c)から軸穴(21b)内に挿入される輪体軸(27)にベアリング(28)を介して回転自在に支架し、ベアリング(28)を介して第2開口穴(21d)を蓋体(34)で閉鎖する。【選択図】図4
