PROBLEM TO BE SOLVED: To provide a trank roller of a crawler type traveling vehicle, which achieves simplification of a structure and which can facilitate maintenance inspection.SOLUTION: A trank roller of a crawler type traveling vehicle includes a roller 52 in which an inlet side for inserting a shaft 53 having an intermediate large-diameter part 65 has an inside diameter enabling insertion of the intermediate large-diameter part 65 and in which an outlet side protruding the tip side of the inserted shaft 53 has an inside diameter smaller than an outside diameter of the intermediate large-diameter part 65. An outer peripheral surface of an O-ring 71 of a floating seal 61 abuts on the roller 52 on the outlet side, and an outer peripheral surface of an O-ring 72 of a floating seal 62 abuts on an inner cylinder 58 on the inlet side.
【課題】構造の簡素化を実現するとともに保守・点検を容易にできる履帯式走行車両の転輪を提供する。【解決手段】中間大径部分65を有するシャフト53を挿入する入口側は中間大径部分65を挿入可能な内径を有し、挿入されたシャフト53の先端側が突き出す出口側は中間大径部分65の外径より小さい内径を有するローラ52を有し、前記出口側ではフローティングシール61のOリング71の外周面がローラ52と当接し、前記入口側ではフローティングシール62のOリング72の外周面が内筒58と当接する構成とする。【選択図】図2
