Front wheels 2a and 2b are supported on the front side of the body frame 1 via an axle 15.

The left and right wheels 2c and 2d on the rear side are supported by a connecting member 21 connected to the tip of an arm 20, and the arm 20 is fixed to the vehicle body frame 1.

On the other hand, a knuckle member 22 is connected to the connecting member 21, and the knuckle member 22 is connected to the connecting rod members 42 and 43.
, The direction of the rear wheels 2c and 2d can be changed.

The front wheel steering mechanism 3 steers the front wheels 2a and 2b by a known link type steering mechanism disposed on the right side of the seat 11, and includes knuckles connected to both ends of a tie rod 30 as shown in FIG. The tie rods 30 are connected to the front left and right front wheels 2a, 2b via a member 31, and the tie rods 30 advance and retreat in the left and right directions in the figure by a steering rotation operation of a steering wheel 32 disposed on the right seat side of the seat 11. When moved, the front wheels 2a, 2b are configured to turn in an arbitrary direction.

On the other hand, a rear-wheel steering mechanism 4 for steering the rear wheels 2c and 2d separately from the front-wheel steering mechanism 3 includes a known link-type steering mechanism and a connecting rod 44 provided on the left side of the seat 11.
The rear wheels 2c and 2d are steered through the like. As shown in FIG. 2, a steering wheel 33 disposed on the left seat side of the seat 11 and a steering wheel 3 on one end 40a are provided.

Further, the other end of the connecting rod 44 is connected to one end of the arm portion 41a, and the rear wheels 2c and 2d are steered by the forward / backward movement of the connecting rod 44.

That is, when the other end of the connecting rod 44 is connected to the arm 41a in a manner as shown in FIGS. 2 and 3, the steering direction of the rear wheels 2c and 2d with respect to the steering wheel 33 is "in phase". And the other end of the connecting rod 44 is
When connected to the arm portion 41a in a manner opposite to that shown in FIGS. 3 and 3, the steering wheel 3 of the rear wheels 2c, 2d
The steering direction for 3 is "opposite phase".

Further, as described above, by changing the position of the hole 41c connecting the connecting rod members 42, 43, even if the steering wheel 33 rotates at the same angle, the movement stroke of each of the connecting rod members 42, 43 is changed. As a result, the rear wheels 2 steered via the connecting rod members 42, 43
The steering angles of c and 2d can be easily changed.

Next, a driving feeling pattern obtained by driving the amusement vehicle configured as described above will be described with reference to FIGS.

First, as a first traveling pattern, as shown in FIG. 5, the left and right steering wheels 32, 33 are not rotated together and are kept in a normal straight traveling state.
"Straight running" similar to the conventional amusement vehicle is obtained.

As the second traveling pattern, as shown in FIG.
By turning the right steering wheel 32 in either the left or right direction and leaving the steering wheel 33 in a normal straight running state without turning, the same "turning direction to the left and right direction" Running ”is obtained.

As a third running pattern, as shown in FIG.
By rotating the steering wheel 33 in either the left or right direction without rotating the right steering wheel 32 without rotating the steering wheel 32, the amusement vehicle is slightly pushed out and turns slightly. Forklift-like running "is obtained.

As the fourth running pattern, as shown in FIG.
Rotate the right steering wheel 32, for example, to the left,
By turning the steering wheel 33 to the right in the opposite direction, the same running as "opposite phase running" in a so-called four-wheel steering vehicle is obtained, and a very small turn can be performed.

As the fifth running pattern, as shown in FIG.
By turning the left and right steering wheels 32, 33 together in either the left or right direction, the same "sliding traveling" as the so-called "in-phase traveling" in a so-called four-wheel steering vehicle is obtained.

In the present invention, in addition to the steering of the left and right steering wheels, the steering of the steering wheel is made symmetrical, or the steering timing is shifted,
Further, by increasing or decreasing the speed, more traveling variations can be arbitrarily obtained.

In the above embodiment, the case where the front wheel steering mechanism 3 is disposed on the right side of the seat 11 and the rear wheel steering mechanism 4 is disposed on the left side of the seat 11 has been described as an example. On the contrary, it is needless to say that the same effect can be obtained also by the arrangement worker.

Further, in the above embodiment, the case where the present invention is applied to a go-kart used in an amusement park or the like has been described as an example.
The present invention is not limited to this. For example, the present invention can be appropriately modified and applied to a mini F1 car and the like.

〔The invention's effect〕

As described above, the amusement vehicle according to the present invention is configured such that the front wheels and the rear wheels can be steered independently of each other. You can enjoy the driving feeling and easily change the steering direction by the rear wheel steering mechanism to the same phase or the opposite phase to the front wheels just by fixing the bracket arm to the left or right side of the base member. The steering angle of the rear wheel can be changed very easily by selectively connecting each end of a pair of connecting rods to a plurality of holes formed on both inclined sides of the base member constituting the bracket. As a result, there is an excellent effect that it is possible to easily realize various driving feelings with one amusement vehicle.
