Abstract
An idler wheel includes a disk shaped idler body, and a plurality of wear plate assemblies disposed to encircle a circumferential surface of the idler body. Each wear plate assembly includes a first wear plate and a second wear plate. The first and second wear plates are adjacent to each other. Each of the first and second wear plates includes a first crawler belt contact surface and a second crawler belt contact surface. Each of the first wear plates includes a first end part that defines an end on a second wear plate side of the first crawler belt contact surface as seen in a plan view, and a second end part that defines an end on the second wear plate side of the second crawler belt contact surface as seen in the plan view. The first end part is inclined with respect to an axial direction.
