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 of the wear plate assemblies has an arc shaped wear plate disposed on the circumferential surface of the idler body, a first fixing member fixing the wear plate to the idler body, and a first fastening tool fastening the first fixing member to the idler body. Each wear plate has a crawler belt contact surface, a guide part protruding from the crawler belt contact surface to guide a crawler belt on the crawler belt contact surface, a first abutting surface abutting the idler body and being perpendicular to an axial direction, and a second abutting surface abutting the idler body and being perpendicular to the axial direction. The first abutting surface faces the second abutting surface in the axial direction.
