プロケツト構造。 In a sprocket having a tooth portion that fits into a drive hole of a rubber crawler in which a metal core is embedded, an annular roller portion is formed on both sides of the sprocket through a space into which the core protrusion of the rubber crawler fits. In order to maintain a non-contact distance between the tooth bottom circle and the core metal abdomen when driving the rubber crawler with the sprocket, the outer diameter of the roller portion is configured to be larger than the tooth root circle of the sprocket. The sprocket structure of the rubber crawler.
