As shown in FIG. 8, a part of the wheel supporting portion 51 provided on the width direction reinforcing member 50 near the upper surface is extended to the wheel supporting portions 51 adjacent to each other in the circumferential direction so that vertical movement and tilting can be restricted. It has been engaged. In this conventional technique, the upper surface of the wheel support portion 51, that is, the projection portion that extends forward or backward (circumferential direction of the crawler body) with respect to the running surface of the wheel, is provided with the notch portion 52 that extends to the other side and has an equivalent length.

止できる。According to the present invention described in detail above, the protrusions 4 of the wheel support portions 8 come into contact with the protrusion receiving portions 5 of the wheel support portions 8 which are adjacent in the circumferential direction in the inner and outer directions, and thus the crawler main body 1 is provided. In a structure capable of suppressing vibration, an elastic body 14 is interposed between at least inner and outer facing portions of the protrusion 4 of the wheel support 8 and the protrusion receiving portion 5 of the wheel support 8 adjacent in the circumferential direction. Since the traveling vibration of the tracked vehicle is elastically suppressed, it is possible to avoid contact between the protrusion 4 and the protrusion receiving portion 5, resulting in a comfortable riding comfort and prevention of noise generation. it can.
