Further, the width of the running belt 51 is substantially equal to the width of the shoes 52, and the width of the supporting plate 42 is substantially smaller than the width of the shoes 52 and is greater than half the width of the running belt 51. Thereby, the crawler plates 52 located in the running surface section 501 can surely obtain sufficient supporting force without sinking.

The limit strips 6 are located above the track unit 5 and are disposed opposite to the main side plates 24 of the frame unit 2 along the width direction W. Preferably, the lengths of the limit strips 6 are substantially smaller than the support. The length of the plate 42. Each of the limiting bead strips 6 extends along the length direction L and includes a connecting piece 61 fixed to the respective main side plates 24, and a bottom surface of the connecting piece 61 extending toward the left and right sides for pressing against the standing plates The tablet 62 of 52. Each of the pressing pieces 62 is used to press the running shoes 52 and bring the running belt 51 close to the supporting plate 42 of the supporting unit 4 to prevent the curved running surface 500 from being deformed. Preferably, the pressing piece 62 of each limiting bead 6 has a buffer layer 621 for contacting the crawling plates 52, a shock absorbing layer 622 connected to the buffer layer 621, and a buffer layer 621 opposite to the buffer layer 621. In the metal layer 623 connected to the shock absorbing layer 622, in the first embodiment, the buffer layer 621 is made of bakelite, has the advantages of smooth low friction characteristics and low hardness, and therefore can reduce the performance The frictional force when the plate 52 contacts, thereby reducing wear. The shock absorbing layer 622 is made of foam and has the function of absorbing vibration.

In detail, each of the limiting beadings 6 has a pressing section 63 for pressing the running surface section 501, and at least one rising section 64 connected to the pressing section 63, the rising section 64 and the running surface A gap is maintained between the segments 501. As shown in FIG. 5, each of the limiting beadings 6 of the first embodiment has two of the rising sections 64, and the rising sections 64 are respectively formed at the front and rear ends of the pressing section 63.
