That is, as shown in FIGS. 3 and 4, the crawler 3
The taper angle θ2 of the engaging portion 1b of the crawler sprocket 1 is set larger than the taper angle θ1 of the engaging portion 3b. (This figure is slightly exaggerated.) In this embodiment, as described above, the taper angle θ2 of the engaging portion 1b of the crawler sprocket 1 is made larger than the taper angle θ1 of the engaging portion 3b of the crawler 3. So,
As shown in FIG. 1, when the vehicle weight P acts on the crawler 3 through the engaging part 1b, the engaging part 3b is pushed apart, and this force spreads to both ends of the crawler 3 in the width direction, causing the crawler to The end portion of No. 3 is pressed in the direction of contact with the ground by the force. Therefore, the ground pressure distribution of the crawler 3 can be made uniform, and the end portion of the crawler 3 can be prevented from curving upward.
