Conventional technology and problems to be solved by the invention In order to adjust the rut distance of a pair of left and right crawler mechanisms, for example, a sliding mechanism that slides one crawler mechanism laterally with respect to the traveling machine frame. In a traveling device having a form in which a sprocket that drives a crawler is slid according to the sliding of the sliding mechanism, and a sliding transmission mechanism that is transmitted to the sprocket is provided, for example, in order to slidingly transmit the sprocket, When a transmission shaft having a spline of a required length is provided on the outer circumference, the spline portion of this transmission shaft is exposed, so that mud is likely to adhere to it. The spline portion of the sprocket and the transmission shaft may be abraded early by mud or easily rusted, which may hinder the sliding of the spline. Also, since the transmission shaft has a length necessary for sliding the sprocket, when the crawler mechanism is set to the reduction side, the transmission shaft projects from the outer end of the crawler. There is a risk that it will interfere with driving.
