Figure 2 is a side view of Figure 1, and Figures 3 to 5 show the movement of the casters when the vehicle, which was traveling in the direction of the arrow A, stops once and then starts traveling in the opposite direction. As an example, Fig. 3 is a bottom view when the car is stopped, Fig. 4 is a bottom view illustrating the yawing moment that the car body receives due to the reversal of each caster when the car starts moving in the opposite direction of the arrow. Figure 4 shows a bottom view of the vehicle body in a state where it is oscillating as a result of the yawing moment applied to the vehicle body, Figure 6 is a front view showing the arrangement of the wheels of the present invention, and Figures 7 and 8 are the vehicle body of the present invention. FIG. 9 is a bottom view illustrating the movement of the caster when it starts moving in the direction of the arrow at the mouth. 1... Vehicle body, 2... Driving wheels, 3... Casters.

Claims

[Scope of utility model registration request]

In an unmanned mobile trolley that has drive wheels 2 on the left and right sides of the center of the vehicle body and casters 3 on the four corners, and that is steered by the difference in rotational speed between the left and right drive wheels 2, the casters 3 have a camper angle α and when the casters 3 are reversed. This unmanned mobile cart is characterized in that left and right casters 3 rotate in opposite directions.
