The upper ends of the springs 86 are respectively connected to the mounting plates 38 of the lower body 30, whereby the left and right sides of the frame 61 and the mounting plates 38 are urged in the approaching direction. That is, the body 11 is always biased toward the neutral position by the balance between the left and right springs 86.

Next, the structure of the steering means 90 will be described. The connecting portions 91 extend rearward from the left and right sides of the fork 73, and the rear end of each connecting portion 91 has one end of a wire 92, respectively. Are connected. Frame 6
A front pulley 93 is attached to the left and right sides of each of the pair 1 at a position obliquely forward of each connecting portion 91 so as to be rotatable in the horizontal direction. In the frame 61, a rear pulley 94 is attached to the left and right sides of the battery 64 on the left and right sides so as to be rotatable in the vertical direction. The wire 92 extending from each connecting portion 91 is hung on a front pulley 93, stretched rearward, further hung on a rear pulley 94, and turned upward. Thus, the tip of the wire 92 extending upward from the rear pulley 94 is connected to the mounting plate 38 of the lower body 30.

When the body 11 is at the neutral position, the tension of the left and right wires 92 is balanced, and the front wheel 75 is directed in the front-rear direction (see the solid line in FIG. 6 and FIG. 8). On the other hand, when the body 11 is tilted to the left, the right mounting plate 38
Is pulled up, the right connecting portion 91 is pulled toward the front pulley 93 by the wire 92, and the front wheel 75 faces left (see the chain line in FIG. 6 and FIG. 9). Similarly, when the body 11 is tilted to the right, the front wheels 75 turn right.

The present embodiment has the above configuration, and its operation will now be described. To take the steering posture of the electric three-wheeled vehicle 10, as shown in FIG. 10, the user sits down on the seating portion 21, places both legs on the footrest portion 55, and holds both hands on the left and right grips 43,
Hold 53. To move forward, the grip 53 is twisted clockwise with the right hand to rotate the movable column 47 and operate the speed control volume 52. Then, the electric motor 69 rotates at a speed corresponding to the amount of rotation of the grip 53, and the vehicle moves forward. The body 11 is automatically set to the neutral position by the balance between the left and right springs 86,
The vehicle goes straight with the front wheels 75 facing forward and backward (see FIG. 8).

In order to perform steering, the body 11 is tilted to the side to be turned while the vehicle is moving forward. That is, for example, when turning to the left, with the grip 53 twisted,
Tilt your body to the left as you lean out of body 11. Then, the body 11 tilts to the left around the tilt axis (pins 77, 79, 82) while extending the right spring 86. At this time, by stretching the right leg placed on the foot rest 55, the body 11 (the seat 21) can be easily tilted. When the body 11 tilts to the left, as shown in FIG. 9, the right spring 86 extends, and the wire 92 attached to the right attachment plate 38 is pulled up. As a result, the wire 92 pulls the connecting portion 91 of the fork 73 via the rear pulley 94 and the front pulley 93, the front wheel 75 turns left, and the vehicle turns left. In the case of turning right, if the body 11 is tilted to the right, the front wheel 75 similarly turns right and can make a right turn. In order to move straight again, the body 11 automatically returns to the neutral position by the urging force of the spring 86 if the body is raised, so that the front wheel 75 returns to the posture in which the front wheel 75 is oriented in the front-rear direction via the wire 92, The vehicle goes straight.

When the vehicle is stopped, the grip 53 is twisted counterclockwise to return to the original position.
Is released and the movable column 47 is
Is returned to the original position, braking is applied to the rotation of the electric motor 69, and the vehicle stops.

As described above, according to the present embodiment, the front wheel 75 is tilted right and left through the steering means 90 by tilting the body 11 right and left about the tilt axis (pins 77, 79 and 82). Turned to. As described above, since the steering method is different from the normal steering operation, a different steering feeling is obtained, and the interest is enhanced.

Further, since the seating portion 21 is integrally linked with the body 11, the operator S moves his / her waist left and right when steering, thereby providing a sporty steering feeling. You can experience.

A tilting shaft (indicated by reference numeral A in FIG. 11) composed of the pins 77, 79, 82
1 is located below the seating surface 21B of the
The height position of the waist of the operator S when the body 1 is tilted left and right is lower than when the body 11 is at the neutral position. That is, when the body 11 is tilted left and right from the neutral position, if the tilt axis is disposed above the seating surface of the seating portion, the operator must lift the waist, which is difficult. According to this, the operator S can easily perform the operation because he only has to lower the waist position.

The chassis frame 60 and the body 11
A pair of springs 86 for biasing the body 11 to the neutral position in the left-right direction are provided between the two members, and the body 11 is automatically biased to the neutral position by these. In addition, when the body 11 is returned from the tilted position to the neutral position, the body can be easily raised according to the urging force of the spring 86.

Further, since the foot rest 55 on which both legs are placed is fixed to the chassis frame 60 side, the body 11 can be easily tilted by stretching the legs.

Further, since the body 11 is provided with grips 43, 53 which can be gripped, the gripping of these allows the body 11 to be smoothly tilted. Furthermore, since the control operation of the traveling speed can be performed by the grip 53 on the right side, both hands are
The tilting operation of the body 11 can be performed while holding the members 3 and 53, and the operation is simpler than, for example, a case where the accelerator pedal or the like is operated with the foot while tilting the body.
