Description of the Related Art Conventionally, as a traveling vehicle such as a golf cart having a function of automatically running by electromagnetic induction with a loop line buried in a traveling path, a two-seater vehicle is mainstream, and one party moves. If so, they had to ride on two traveling vehicles. However, in recent years, a five-seater type has been developed so that the number of people in one party (up to five people) can move at one time. This has a seat for two at the front and a seat for three at the rear. For example, introduction of such a multi-seat traveling vehicle at a golf course or the like leads to a reduction in the number of vehicles and can save storage space for the vehicle.

However, the conventional Japanese Patent Application Laid-Open No. Hei 7-117732
In the five-seater traveling vehicle shown in FIG. 5, the wheel base between the front and rear wheels is longer due to the arrangement of the front and rear seats than the two-seater traveling vehicle, and the traveling radius is correspondingly longer. Therefore, when using a two-seater traveling vehicle that was the mainstream until then, when introducing a new five-seater one to a golf course that had laid a running path based on it, based on a longer wheelbase, The runway had to be rebuilt. Furthermore, when the system for automatically controlling the traveling vehicle on the traveling road, such as the five-seater, is adopted, the operation of changing the traveling road involves a loop wiring operation of the traveling road for performing the electromagnetic induction control. It was expensive, and in the end there were cases where the introduction of a five-seater car had to be abandoned.

Therefore, the present applicant has proposed a traveling vehicle shown in FIG. In the two traveling vehicles, the front wheels are suspended below a flat front seat base, and the wheel base length between the front and rear wheels is substantially the same as that of a two-seater traveling vehicle.

[0005] However, when the front wheels are provided below the front seat, when the outside foot of the occupant seated on the front seat protrudes from the running vehicle while the running vehicle is running, the front wheel is not provided. Your feet may get caught in the front wheels. Therefore, as described below, measures have been provided for both of the traveling vehicles.

First, in the traveling vehicle shown in FIG. 6, means for preventing the foot from being entangled with the front wheels will be described together with the overall construction of the traveling vehicle.
