To provide a crawler vehicle for transportation of excavated earth, which is increased in the volume of a bowl thereof while suppressing the size and weight of the entire vehicle to the minimum.

The crawler vehicle is equipped with the bowl 11 which is mounted thereon at the center of right and left traveling crawlers 20, for automatically excavating the earth and storing the earth therein. According to the crawler vehicle, an interval between sprockets of each traveling crawler 20 is the same with the interval of a conventional traveling crawler, and an axial center of a hollow shaft 24 of the traveling crawlers 20 connected to an upper body 10 is conformed to a rotation center of a driving sprocket 21, and therefore the entire bodies of the traveling crawlers 20 are brought frontward with respect to the upper body 10 relative to the conventional crawlers, which leads to frontward extension of the bowl 11 by a distance corresponding to the frontward shift of the traveling crawlers 20, whereby the volume of the bowl 11 is increased.
