る。Accordingly, the body 6 of the electric tricycle has only the size of the cover 6a that covers the rear wheel 11 and the electric motor 14,
The overall height is significantly reduced. Therefore, it can be easily stored even in a narrow place, and can be easily loaded in a luggage compartment of a passenger car. Therefore, it is possible to load and move on the passenger car from the departure to the destination or from the destination to the return.

なくても問題はない。When the vehicle is traveling, the lock device 1r is released and the handle shaft 1 is set up, the handle shaft 1 is automatically locked, and if the seat 10 is erected, the vehicle can run immediately. In this case, self-propelled travel between the departure point and the destination is carried out by a passenger car or the like, so that the traveling range at the destination is limited and the traveling distance is usually not so long. Also, there is no need to make the body strength so strong, and there is no problem if the capacity of the storage battery to be loaded is not so large.

Thus, the weight can be reduced to about g as compared with the conventional case, so that the device can be used in a small size and light weight. In the above-described embodiment, if a power cutoff switch (not shown) for turning off the power of the electric motor 14 is provided in addition to the brake lever 1b provided on the handle shaft 1, if the main switch of the electric motor 14 is provided, Even in the contact state, the power supply is always shut off when the brake is operated, so that the driving force is continuously applied even when the brake is applied, and waste is prevented, and safe driving is maintained.

If the circuit of the regenerative electromotive force is turned on at the same time as the power supply to the motor 14 is cut off, the electromotive force is stored in the storage battery 16 each time the flake is applied.
Since it is supplied to the side, energy can be effectively used.

なく車体を安全に止めて置くことができる。According to the electric tricycle of the present invention, the electromagnetic clutch is automatically mechanically connected to the rotating shaft of the electric motor by shutting off the power supply. Therefore, the vehicle body can be safely stopped and placed without particularly performing a brake operation.

運転ができる。In the electric three-wheeled vehicle according to the second aspect, since the drive power is always shut off when the brake is operated, wasteful power storage can be avoided, and at the same time, there is a dangerous situation in which the drive is continued despite the brake being applied. Is reliably prevented and safe driving is possible.

姿勢で収納でき、保管場所が非常に狭くて済む。According to the third aspect of the present invention, when the brake is applied, energy is recovered by regenerative braking, so that efficient operation can be performed. According to the configuration of claim 4, since the seat is removed and the handle shaft is folded, the size becomes smaller, so that it can be easily transported even in the luggage compartment of a passenger car, and can easily return to and from the destination. Since the traveling range is narrow, the vehicle body and electric motor can be reduced in size and weight, and can be used very easily. Further, when the steering wheel is folded and stored, the bumper can be stored in an upright posture like a stand, so that the storage space can be very small.
