Next, a training method using the training vehicle will be described. This lesson is suitable for junior high school students, elementary school students, etc., who are under the driving age, and those who learn about the structure of automobiles. Participants wear gloves and make preparations appropriate for operating the vehicle and handling parts. For example, 4 to 5 participants
As a group, one car and trainer are assigned to each group. First, the trainer explains the structure of each part of the car. In this case, since the shock absorber 53, which is a so-called suspension-related component of the suspension device, is exposed at the upper portion of the frame body 1, its operation can be confirmed by shaking the frame body 1 vertically. Meanwhile, shock absorber
Although 53 is exposed on the frame body 1, the front shock absorber 53
Is on the outside of the vertical rod 56, and the shock absorber 53 on the rear side is
Since it is behind L, 4R, the driver sitting on the seat does not touch. Also, try attaching and detaching the front wheels 25. In this case, the pine needle pin 26 is pulled by bending the bent portion 26B.
Can be easily pulled out, after pulling out the pine needle 26, the wheel
25 is detached from the wheel mounting shaft 24, and conversely, the wheel 25 is mounted, and the insertion portion 26A is inserted into the insertion hole 24A, whereby the engagement portion 26
C is locked on the outer surface of the wheel mounting shaft 24, and the distal end side of the engaging portion 26C and the insertion portion 26A are fitted by elastic restoring force, so that the pine needle pin 26 is mounted in a retaining state. Thus, the wheel 25 can be easily attached and detached using the pine needle pin 26,
By removing the 25, the wheel mounting member 22 can be visually recognized directly, so that you can learn the structure of the car by looking at the oblique rod 22D that has become oblique for camber, etc.
For example, with the wheels 25 removed, the user can operate the handle 43 to see changes in the direction of the wheel mounting shaft 24 and the like.
In addition, the handle 43 removes the nut body 45,
When it can be removed from the handle shaft 32 and is attached, the three long holes 44 are aligned with the male screw rods 42 and tightened and fixed by the nut body 45. In this case, since the male screw rod 42 is inserted into the long hole 44, the insertion is easy, and after the insertion, the handle 43 is correctly inserted into the handle shaft 32 by the three sets of long holes 44 and the male screw rod 42. Can be aligned and fixed. Further, the rear wheel 25 is removed from the drive shaft 73 in the same manner as the front wheel 25. Also in this case, the wheel 25 can be removed by operating the pine needle pin 26, and the rear wheel 25 is a member on which the driving force of the drive shaft 73 and the braking device 91 act on the braking force. By inserting the tip of the transmission shaft 77 into the engagement hole 78 of the wheel 25 and attaching it in this state, it can be seen that the wheel 25 and the drive shaft 73 rotate integrally. In this way, the functional structure of the wheels 25, the steering wheel 43, and the like is learned, and then, the traveling and the like are learned. First, one of the groups sits in seat 12, and the rest push the car. In this case, the vehicle is pushed so as to proceed at about the walking speed, and the driving vehicle depresses the brake pedal 101 to learn about braking of the brake. In learning this brake, the frame 1
The brake body 92, the hydraulic cylinder 93, and the reserve tank 95 are exposed at the rear of the vehicle, so that the brake pedal 101 is depressed in a stopped state so that the operation of the hydraulic cylinder 93 and the brake body 92 is directly visually recognized. The operation of the connecting mechanism 105 for operating the hydraulic cylinder 93 can also be confirmed. Furthermore, in order to confirm the braking of the brake, the vehicle is pushed while the brake pedal 101 is depressed, and the braking is confirmed. On the other hand, the frame body 1

When the fastening rod 130 is removed in this manner, the electric motor 126 can be lifted and removed from the motor mounting seat 121, and at the same time, the coupler 144 is removed. In addition, the chain 135 can be detached from both sprockets 133 and 134, and the detached chain 135 can be hung on a chain hook 137 as shown in FIG. That is, since the chain 135 cannot be removed from the drive shaft 73, the chain 135 can be hung without hindrance when the electric motor 126 is detached by hanging the chain 135 on the chain hook 137. As will be described later, when the rear shock absorber 53 is removed, the wheel mounting member 71 becomes free, and when the rear portion of the frame body 1 is lifted, the rear end of the wheel mounting member 71 is lowered. Chain 13 mounted
5 is locked to the drive wheel 73, and no more
71 never goes down. On the other hand, when mounting the electric motor 126, the chain 13 is attached to both sprockets 133 and 134.
5 and the positioning projections 124, 124 have elongated holes 128, 128, respectively.
And the electric motor 126 is placed such that the engaging projection 129 abuts on the rear edge of the front mounting leg 127M. In this state, the electric motor 126 can move forward by the length of the elongated hole 128. For example, as shown by an arrow Y in FIG.
If the left front side of 126 is pushed backward, the drive sprocket 133 moves to the front side indicated by the arrow y by the principle of lever around the engagement projection 129, and it is possible to apply a predetermined tension to the mounted chain 137, In this state, the tightening rod 130 is screwed into the male screw portion 125 and tightened and fixed, and thus the mechanism of the power system can be learned. Also, the coupler 144 is connected as an electric system.

Further, in the training of the electric system, when the main switch 141 is turned on and the accelerator pedal 145 is depressed, the vehicle runs, and further, the changeover switch 142 is operated to select the forward or backward travel. Further, it can be seen that the instructor holds the extension cord 167, pulls the extension cord 167 and removes the male coupler 163 from the female coupler 163A, whereby the electricity is cut off and the electric motor 126 stops. In this case, the switches 141 and 142 and the stop device 161
Are arranged on one side, which is the other side of the frame body 1, so that the instructor can stand on the right side of the frame body 1 and smoothly explain and operate them.
