PROBLEM TO BE SOLVED: To provide an idler device of a crawler type traveller having a configuration such that adhesion of earth and sand which enter between an underside of an idler bearing and a lower plate part of an idler guide can be prevented, and attachment and detachment of an idler with respect to the idler guide can be easily achieved.SOLUTION: An idler bearing 11, which rotatably supports a central axis 10 of an idler 4, is provided at both ends of the central axis 10. At a forward end of a side frame, a bracket 9 having an idler guide 13, which so guides the idler bearing 11 as to be movable in a cross direction. The side frame is provided with an adjuster for adjustment of a position of the idler bearing in the cross direction, on which a press spring for pressing the idler bearing forwards is additionally provided. An underside 11c of the idler bearing 11 is inclined with respect to a top face 11a thereof in such a manner that a vertical width t1 of a rear side of the idler bearing 11 is narrower than a vertical width t2 of a front side.

    【課題】アイドラベアリングの下面とアイドラガイドの下板部との間に入る土砂の固着が防止されると共に、アイドラのアイドラガイドに対する着脱が容易となる構成を有する履帯式走行装置のアイドラ装置を提供する。【解決手段】アイドラ4の中心軸10の軸方向の両端に、中心軸10を回転可能に支持するアイドラベアリング11を設ける。サイドフレームの前端に、アイドラベアリング11を前後方向に移動可能に案内するアイドラガイド13を有するブラケット9を設ける。サイドフレームに、アイドラベアリング11を前方に押圧する押圧スプリングを付設したアイドラベアリング前後位置調整用アジャスタを設ける。アイドラベアリング11の後側の上下幅t1が前側の上下幅t2より狭くなるように、アイドラベアリング11の下面11cを上面11aに対して傾斜させる。【選択図】図3
