ABSTRACT:
A guide roller assembly for use in a guide roller mechanism of a crawler type vehicle, including a support shaft fixedly provided on a truck frame and a guide roller rotatably mounted on the support shaft through bearings. The guide roller has an integral unitary body structure of a stepped cylindrical shape having a radially bulged portion formed integrally by plastic deformation in an axially intermediate portion between cylindrical end portions of a smaller diameter, and having a uniform wall thickness over the entire length of the guide roller. The guide roller is improved in strength and can realize a substantial cut in production cost.
