PROBLEM TO BE SOLVED: To install a member capable of preventing mud from splashing over an upper roller in a crawler travel device; and to install the member efficiently by post installation also on an existing crawler travel device.SOLUTION: Such a constitution is adopted that an upper roller 10 is supported by a truck frame 2 through a bearing member 11 having a roller fixing part 11a where right and left ends of a roller shaft 10a are fixed, and that a roller cover 13 for covering the periphery of the upper roller 10 is fixed to the bearing member 11 by being co-fastened by a fixing bolt 12 for fixing the roller shaft 10a to the roller fixing part 11a.SELECTED DRAWING: Figure 3
【課題】クローラ走行装置において、上部ローラに泥土がかかってしまうことを防止する部材を設けるとともに、該部材を、効率よく、しかも既存のクローラ走行装置にも後付けで取り付けできるようにする。【解決手段】上部ローラ10を、ローラ軸10aの左右端部が取付けられるローラ取付部11aを有した支持部材11を介してトラックフレーム2に支持するとともに、上部ローラ10の周囲を覆うローラカバー13を、ローラ軸10aをローラ取付部11aに取付けるための取付けボルト12で共締めして支持部材11に取付けるように構成した。【選択図】図3
