In this case, the door part 26 can be opened and closed while maintaining a sense of unity with the main body part 25. Moreover, since the door part 26 can be moved to the back side of the main-body part 25 by opening the door part 26, for example, the door part 26 can be moved to the opposite side to a parked vehicle, the door part 26 is obstructive. The inconvenience such as becoming can be further suppressed.

  Specifically, the main body portion 25 is formed in a columnar shape, and a storage portion 31 is provided by forming a concave portion on the side surface thereof so that the charging cable 21 can be stored in the concave portion (the storage portion 31) of the main body portion 25. did. The door portion 26 is slid by a rotation with the center axis of the main body portion 25 (the center of the through-hole portions 28a and 29a) as a circular center and the center axis as a rotation center. . In this case, when the door portion 26 is opened and closed, the door portion 26 can be prevented from projecting on either side with respect to the outer peripheral surface 25a of the main body portion 25, so that the door portion 26 becomes an obstacle when the vehicle is parked. It can be further suppressed.

  A winding member 35 for winding the charging cable 21 in the storage state of the charging cable 21 is provided in the storage portion 31, and the charging cable 21 is folded up and down along the longitudinal direction of the main body portion 25 around the winding member 35. I did it. And the circular arc surface parts 38 and 39 which make circular arc shape in the cable winding direction were provided in the upper and lower ends of the winding member 35. In this case, since the bending radius of the charging cable 21 at the arc surface portions 38 and 39 can be relatively large in the winding state of the charging cable 21, the vehicle is charged with the charging cable 21 partially wound around the winding member 35. However, the charging cable 21 can be prevented from generating heat and becoming hot. As a result, the vehicle can be charged while the charging cable 21 is wound.

  Specifically, the radii of the arcuate surface portions 38 and 39 are set to be more than half the outer peripheral radius of the main body portion 25. Thereby, since the bending radius of the charging cable 21 in the circular arc surface portions 38 and 39 can be increased, heat generation of the cable 21 when charging the vehicle while the charging cable 21 is wound can be further suppressed.

  In the closed state of the door part 26, a drawer port 51 for drawing the charging cable 21 out of the main body part 25 is provided between the door part 26 and the main body part 25 on the closing side of the door part 26 in the opening / closing direction. In this case, since the charging cable 21 can be pulled out from the outlet 51 and connected to the vehicle with the door portion 26 closed, the vehicle can be charged with the door portion 26 closed. As a result, it is possible to prevent inconvenience such as dust entering the storage unit 31 during charging of the vehicle.

  The drawer port 51 is provided in the upper part at the boundary between the door part 26 and the main body part 25 on the closed side of the door part 26. In this case, the charging cable 21 can be pulled out of the main body 25 at a relatively high position with respect to the floor 15 of the garage 11. Therefore, when the charging cable 21 is connected to a vehicle, it can suppress that the charging cable 21 contacts the said floor surface 15, and can suppress that the charging cable 21 gets dirty as a result.

  When the vehicle C is in a predetermined position for charging in the garage 11, the guide light 65 is blinked. As a result, the vehicle C can be stopped at a predetermined position. Then, the charging cable 21 having a length corresponding to the predetermined position is pulled out from the outlet 51 and connected to the vehicle C, so that the vehicle C can be charged with the charging cable 21 partially wound.

In this case, the pair of slide rails may be provided in the direction extending in the vertical direction and at both ends in the circumferential direction of the door.

  (2) In the above embodiment, the main body portion 25 has a columnar shape, and the arcuate door portion 26 is slid along the outer peripheral surface 25a of the main body portion 25 in accordance with the main body portion 25. However, this may be changed. . For example, it is good also as a structure which makes a main-body part prismatic shape, and slides a flat door part along one side among the four side surfaces. Specifically, the main body portion is formed in a rectangular box shape (hexahedron) that is long in the vertical direction, and the inside is used as a storage portion for the charging cable 21, and an opening that communicates the inside and outside of the storage portion is formed on one side surface thereof. . And the structure which opens and closes a storage part by providing the flat door part which opens and closes the opening part in the outer surface of a main-body part, and sliding the said door part along the said outer surface (for example, left-right direction) is considered. It is done. In addition, as a structure which slides a door part, the structure slid using the rail mentioned above is mentioned. In this case, since the door portion can be prevented from protruding from the front surface of the main body portion when the door portion is opened and closed, inconveniences such as the door portion interfering when the vehicle is parked can be suppressed.

  Moreover, you may form the main-body part 25 as columnar shapes other than column shape or prismatic shape. For example, it is good also as a shape which cut | disconnected and removed the part of the rear side in the main-body part 25 (specifically the part behind the accommodating part 31) in the surface parallel to the flat surface 25b. In this case, the storage portion 31 can be opened and closed by sliding the door portion 26 along the arc surfaces remaining on both sides of the cut surface formed in the main body portion 25.

You may form so that the whole side surface may become a circular arc surface. As the main body portion having such a shape, for example, one obtained by removing the upper and lower flange portions 28 and 29 from the main body portion 25 of the above embodiment can be considered. In this case, since there is no concave portion on the side surface of the main body, the inner area of the door portion on the front side of the flat surface of the main body serves as the storage portion. And a storage part is opened and closed by sliding the door part along the circular arc surface of a main-body part.

  (4) In the above embodiment, the winding member 35 is configured as an integral body including the arc surface portions 38 and 39. However, this is changed, and the arc surface portions 38 and 39 are formed by separate members and wound by the respective members. The member 35 may be configured. For example, each arcuate surface portion is formed by a pair of winding portions made of a fan-shaped (semi-circular or the like) plate-like member, and the flat surfaces 25b of the main body portion 25 are arranged such that the convex portions of the pair of winding portions face opposite sides. It is possible to arrange them vertically. In this case, the charging cable 21 may be alternately wound around the arc surface portion of each winding portion.
