を防止することはできなかった。In a traveling vehicle having a crawler traveling device, when the traveling vehicle rotates in place, the rotation of one of the left and right crawler traveling devices is generally stopped, and the other crawler traveling device is stopped. A method has been used in which only the traveling device is rotated to perform rotation around the stopped crawler traveling device. However, in this method, since a large frictional force is generated between the crawler traveling device on the stop side and the traveling road surface, when the rotation is performed in the direction A, the space between the crawler belt and the contact wheel is shown in FIG. As described above, the external forces M and N act in the direction of the arrow. At this time, if the grounding wheel is constituted by the outer wheel 11 as shown in FIG.
As shown in FIG. 3 (b), one side of the abduction wheel 11 floats off the crawler belt 7, causing the wheel to slip off. or,
4A, the two ends of the crawler belt 7 are easily turned up in a portion where the core metal does not pass as shown in FIG. 4B. This caused the crawler belt 7 to be damaged. Further, even if the grounding wheel is constituted by a triple wheel 13 as shown in FIG. 5A, the triple wheel 1 as shown in FIG.
The intermediate wheel portion 3 floated from the crawler belt 7, and it was not possible to prevent the wheel from falling off.

At this time, the crawler belt 7 tends to be turned up at a portion where the core metal 18 does not pass, but the crawler belt 7 is securely pressed down by the outer roller portions 9, 9 constituting a triple roller. The turning up is prevented.
Also, the outer diameter of the outer rolling portions 9 of the triple rolling wheel is
And the contact surface with the crawler belt 7 is formed on the inclined surface at a predetermined angle θ toward the left and right outwardly upward when viewed from the front. 7 is located above the tilt fulcrum Q of the crawler belt 7 with respect to the conventional triple wheel 13 shown in FIG. As a result, as compared with the conventional triple roller 13, the separation start angle between the intermediate roller portion 10 and the crawler belt 7 due to the inclination of the crawler belt 7 is increased, and the non-removable inclination range of the crawler belt 7 with respect to the triple roller is increased. It will be.

れを規制することができるのである。The outer races 9, 9 of the triple rollers 2, 4 have an outer diameter smaller than that of the middle race 10, and the contact between the outer races 9, 9 and the crawler belt 7 is further reduced. 2B, the crawler belt 7 is inclined with respect to the triple rollers 2 and 4 because a slanted surface having a predetermined angle θ is formed in the right and left directions outward and upward when viewed from the front. As shown in the figure, the intermediate wheel portion 10 sandwiched between the left and right retaining projections 8, 8 is hardly lifted from the crawler belt 7, and the wheel-preventing property can be improved. Further, since the center rolling wheel 3 arranged on the turning center O at the time of turning on the spot is not affected by the external forces M and N at the time of turning on the spot, as shown in FIG. Thus, the crawler belt 7 can be restricted from being laterally displaced between the crawler belts 8 and 8.
