PROBLEM TO BE SOLVED: To provide an idler which can suppress breakage of a fastener for fixing an abrasion plate, and a crawler type travel device.SOLUTION: An abrasion plate assembly 42 comprises a first fastener 203, a first stationery member 201, and a circular arc-shaped abrasion plate 200. The first fastener 203 is fastened to an idler body 41. The first stationery member 201 comes in contact with the first fastener 203 and the idler body 41 and is held therebetween. The abrasion plate 200 includes a first engagement part 200e which is engaged between the first stationery member 201 and the idler body 41. The abrasion plate 200 includes a first contact surface 200S and a second contact surface 200T. The first contact surface 200S comes in contact with the idler body 41, and is perpendicular to an axial direction of a central axis AX of rotation. The second contact surface 200T comes in contact with the idler body 41, and is perpendicular to the axial direction. The first contact surface 200S faces the second contact surface 200T in the axial direction.

    【課題】摩耗プレートを固定するための締結具の破損を抑制可能なアイドラ及び履帯式走行装置を提供する。【解決手段】摩耗プレートアッセンブリ42は、第1締結具203と、第1固定部材201と、円弧状の摩耗プレート200とを有する。第1締結具203は、アイドラ本体41に締結される。第1固定部材201は、第1締結具203とアイドラ本体41とに当接して挟まれる。摩耗プレート200は、第1固定部材201とアイドラ本体41の間に係止される第1係止部200eを含む。摩耗プレート200は、第1当接面200Sと第2当接面200Tとを含む。第1当接面200Sは、アイドラ本体41と当接し、回転中心軸AXの軸方向に対して垂直である。第2当接面200Tは、アイドラ本体41と当接し、軸方向に対して垂直である。第1当接面200Sは、軸方向において第2当接面200Tと対向する。【選択図】図4
