To solve the problem of derailment of a crawler belt caused by entry and staying of mud brought up by the crawler belt, floating of the crawler belt, deposition of mud on a follower wheel frame, pushing-up of the crawler belt, and application of an outward pushing force in the follower wheel of a rear side on which the crawler belt is wound.SOLUTION: In a follower wheel (14) of a rear side on which a crawler belt (15) is wound, mud lead-out means (17) is provided for dropping mud brought up by the crawler belt (15) downward and simultaneously leading out the mud toward the inside of a tread between left and right traveling crawlers (2) and (2).SELECTED DRAWING: Figure 3
【課題】クローラベルトを巻回する後部側の従動輪において、クローラベルトが持ち回ってくる泥土が侵入、滞留し、クローラベルトが浮き上がり、従動輪フレーム上にも泥土が堆積し、クローラベルトを押し上げ、且つ、外側に押し出す力が加わり、クローラベルトの脱輪が発生する問題があった。【解決手段】クローラベルト(15)を巻回する後部側の従動輪(14)において、クローラベルト(15)が持ち回ってくる泥土を下方へ流出落下させると同時に左右の走行クローラ(2),(2)間における轍間内側方向へ泥土を導き出す泥土導出手段(17)を設ける。【選択図】 図3
