However, in the illustrated embodiment, the wheel 12 is composed of one front wheel 12a and a pair of rear wheels 12b . In the case of a three-wheeled vehicle having one front wheel 12a, it can be said that the steering of the front wheel 12a can be performed more easily. The wheel 12 is capable of traveling while being rotated by the rotational force transmitted from the driving motor. And the transmission of power to the wheel 12 for convenience of illustration and explanation are widely implemented at present, so that a detailed description thereof will be omitted.

It can be said that the electric vehicle of the present invention has the frame 10 as the base for providing the basic structure and the components described below are installed or supported directly or indirectly on such a frame 10. [ The above-described wheel 12 can also be said to be rotatably supported on the frame 10. For example, a support shaft for rotatably supporting the wheel 12, a rotation shaft for transmitting rotation power, and the like are basically supported directly or indirectly to the frame 10.

On the frame 10, a working chair 14 is rotatably installed. That is, the chair support shaft 14a for supporting the working chair 14 is rotatably supported with respect to the frame 10. Accordingly, it is possible for the operator to easily harvest the adhesive around the chair 14 while sitting on the chair 14. And, if necessary, it will be possible to work on the harvested material in the surrounding area by changing the working position by running the electric car.

The upper end of the steering shaft 22a provided in the vertical direction to the frame 10 at the front portion is provided with a handle 22 to be held and controlled by the user and a fork 22b connected to the lower portion of the steering shaft 22a, A front wheel 12a is rotatably installed. Thus, it can be seen that steering control using the handle 22 can be facilitated.

The basket supporting portion 24a is configured to support a harvested container, such as strawberries. In the illustrated embodiment, the basket supporting portion 24a has a circular rim shape and has a shape in which the rim portion of the basket supporting portion 24a can be hung and supported while the circular basket is inserted.

The basket supporting portion 24a may be used in supporting a bag or the like such as a large bag which can be used to store unnecessary items when carrying out work on the agricultural fruit harvested in the greenhouse. When the basket supporting portion 24a is used to support such a bag, it is preferable to provide a rotation supporting plate 28 for supporting the lower end of the bag at a lower portion of the steering shaft 22a.

It is preferable that the pivot support plate 28 is formed so as to be formed of a wire of a certain thickness and to be folded upward. It is preferable that an elastic clamper 28a capable of holding the wire corresponding to the upper end portion of the pivotal support plate 28 in a state where the pivotal support plate 28 is folded upward is elastically received in the steering shaft 22a Do.

The basket supporting portion 24a is connected to the cylindrical supporting portion 25a. The cylindrical supporting portion 25a is rotatably supported with respect to the connecting member 25b in the direction of the water. That is, a support shaft (not shown) protruding upward is provided at the outer end of the connecting member 25b, and the cylindrical support portion 25a is rotatably supported by the support shaft.

The connecting member 25b is connected to the main cylindrical supporting portion 25c. The main cylindrical support portion 25c is rotatably supported on the steering shaft 22a. Needless to say, the main cylindrical support portion 25c can be held at a predetermined position on the steering shaft 22a. It is also possible to fix the main cylindrical supporting portion 25c to a predetermined position by fixing another ring member on the upper and lower sides of the main cylindrical supporting portion 25c by welding or the like.

As another embodiment, the configuration as shown in Fig. 2 may be possible, and this configuration is also applicable to the basket supporting portion 24b provided at the rear of the electric cart of the present invention. In the illustrated embodiment, a circular ring-shaped groove 22c is formed on the outer circumferential surface of the steering shaft 22a. In the state where the fastening bolt C passes through the main cylindrical support portion 25c, And its end is fixed to the base 22c.

Therefore, when the fastening bolt C is completely fixed, the main cylindrical supporting portion 25c can not rotate and is fixed. When the fastening bolt C is slightly loosened so that the end portion of the bolt C does not come out of the ring groove 22c, the main cylindrical support portion 25c can rotate but move downward It will be in a state that does not exist. The configuration of the main cylindrical support portion 25c is also applied to a rear support shaft 25 provided on the rear side of the cart and a plurality of basket support portions 24b supported on the rear support shaft 25 It will be possible.
