The lower part of the frame main body 54a is rotatably supported by the shaft body 54f at the rear part of the floor body 20.

  The seat support mechanism 55 is a mechanism for setting the seating position and the second storage position of the seat body 50, and includes a rear support portion 56 and a second lock mechanism 57. The rear support portion 56 includes a support main body 56a that protrudes upward from the rear portion of the floor body 20, and a support surface 56b that is formed on the upper portion of the support main body 56a and supports the back-side frame body 54. The back frame body 54 is supported at the sitting position by receiving the body 54 at the support surface 56b. FIG. 7 is a perspective view showing the vicinity of the second lock mechanism 57. The second lock mechanism 57 includes a lock member 58, a lock support portion 59, and a locked portion 61. The lock member 58 includes a lock main body 58a, a lock engaging portion 58b formed at one end of the lock main body 58a, and a handle 58c formed at the other end of the lock main body 58a. The lock support portion 59 projects from the upper surface of the floor body 20 and supports the lock member 58 so as to be slidable in the horizontal direction by the support recess 59a. The locked portion 61 is a hole formed in the side portion of the frame main body 54a of the back frame body 54, and the second locking mechanism 57 is set to the locked position and the unlocked position by moving the locking member 58 back and forth. .

  In such a configuration of the seat body 50, the leg portion 53a of the frame main body 53 is erected and the lock engaging portion 58b of the lock member 58 is inserted into the locked portion 61, whereby the back frame body 54 and the frame The seat body 50 can be set at the seating position by fixing the main body 53 and supporting the back frame body 54 by the rear support portion 56. On the other hand, by pulling out the lock member 58 from the locked portion 61 and setting the second lock mechanism 57 to the non-lock position, the frame main body 53 can be set to the second retracted position (see FIG. 8).

(3) Steering and storing operation of the electric vehicle 10 In the electric vehicle 10, the user sits on the seat seat portion 52 of the seat body 50 and operates each button of the operation portion 43 in the use state of FIGS. It can drive by this. The electric vehicle 10 can be stored in the storage state shown in FIG. 9 from the use state shown in FIGS. The electric vehicle 10 can be stored by the following work. First, in the second lock mechanism 57 shown in FIG. 7, by grasping the handle 58c of the lock member 58 and pulling the handle 58c forward, the lock member 58 is guided by the lock support portion 59 and moved in the same direction. The engagement with the locked part 61 formed in 54 is released. Then, as shown in FIG. 8, the frame body 53 and the back frame body 54 are tilted forward and overlapped on the floor body 20. Thereafter, the operation unit 43 is rotated in the direction of the arrow about the shaft body 43 a and is aligned with the handle body 41. Further, by holding the handle 47d of the lock member 47 shown in FIG. 4 and sliding the lock member 47 to the front side of the figure, as shown in FIG. The engagement with the first lock engagement portion 47b is released. Then, as shown in FIG. 9, the handle body 41 is tilted down. Then, by sliding the lock member 47 toward the handle main body 41 in a posture in which the handle main body 41 is tilted, the second lock engaging portion 47c of the lock member 47 hits the storage position fixing portion 49b of the handle main body 41. The handle body 41 is fixed at the first storage position. Thus, the electric vehicle 10 is stored on the floor body 20 so that the seat body 50 and the handle 40 overlap with each other, and the positions of the handle 40 and the seat body 50 are fixed.

  On the other hand, in order to change the electric vehicle 10 from the state shown in FIG. 9 to the state shown in FIG. That is, after pulling the lock member 47 of the first lock mechanism 46 of the handle support mechanism 44 forward, the handle main body 41 is raised (FIG. 8), and the lock member 47 is further returned to thereby fix the handle main body 41 to the front fixing portion. 45 and the lock member 47 are fixed to the floor body 20. Further, the seat frame 50 is rotated so that the back frame body 54 stands up, and is further locked by the second lock mechanism 57 (FIG. 7) of the seat support mechanism 55. Thereby, the electric vehicle 10 is set to a use state.

(4) Operation and effect of the embodiment The configuration of the above embodiment has the following effects.
(4) -1 In the electric vehicle 10 according to the embodiment, as shown in FIGS. 7 and 8, the lock position of the second lock mechanism 57 of the seat support mechanism 55 is released and the seat body 50 is placed on the floor body 20. Further, as shown in FIG. 9, the lock position of the first lock mechanism 46 of the handle support mechanism 44 is released and the handle 40 is stacked on the sheet body 50, that is, the sheet body 50 and the floor body 20 are overlapped. The handle 40 is stacked. Therefore, with such a simple configuration, the electric vehicle 10 can store the handle 40 and the seat body 50 in a compact manner with the handle 40 and the seat body 50 overlapped on the floor body 20.

(4) -2 The handle 40 and the seat body 50 are firmly supported by the handle support mechanism 44 and the seat support mechanism 55. If the first lock mechanism 46 and the second lock mechanism are set to the unlocked position, The seat body 50 and the handle 40 can be tilted toward the floor body 20, and the storing operation is easy.

The present invention is not limited to the above-described embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.
In the above-described embodiment, the handle 40 is stored so as to overlap the sheet body 50, but the present invention is not limited to this, and the sheet body 50 may be stored so as to overlap the handle 40.
Moreover, in the said Example, although the motor was used as a drive source, it is not restricted to this, A small engine etc. may be sufficient.
