The wire layer 108 is a member that covers the surface of the insulator layer, and is made of a metal such as iron or stainless steel.

  In the charging stand 200 configured as described above, a user who charges an electric motorcycle inserts a regular key into the key cylinder 203 of the charging stand 200 and rotates it in a predetermined direction. Then, the engagement between the catch portion 213 and the lock portion 223 is released, and the outlet upper cover 210 is unlocked. Thereby, the user can open the outlet upper cover 210 outward. Similarly, the outlet lower cover 220 housed inside the outlet upper cover 210 can also be opened outward.

  Next, the user inserts the plug 102 of the charging cord 101 into the outlet 201 a of the outlet 201. Then, as shown in FIG. 19, the outlet lower cover 220 is closed, and then the outlet upper cover 210 is put on the outlet lower cover 220. When the outlet upper cover 210 is put on the outlet lower cover 220, a circular opening hole 230 is formed by the lower cover slit 221 and the upper cover slit 211. The charging cord 101 is held in a state of passing through the opening hole 230. At this time, the catch portion 213 of the outlet upper cover 210 is inserted into the lock portion 223 (not shown in FIG. 19), and the catch portion 213 and the lock portion 223 are engaged. As a result, the entire outlet cover 202 is locked. In this locked state, the outlet cover 202 does not open even when an external force is applied to the outlet cover 202.

  Further, as shown in FIG. 20, the flange portion 105 provided on the plug 102 is positioned inside the outlet cover 202 in the locked state. The flange portion 105 has a larger diameter than the opening hole 230 formed when the outlet upper cover 210 is put on the outside of the outlet lower cover 220. For this reason, even if the charging cord 101 is pulled, the flange portion 105 does not come out of the opening hole 230.

  On the other hand, when a regular key is inserted into the key cylinder 203 and rotated in a predetermined direction, the engagement between the catch portion 213 and the lock portion 223 is released, and the outlet upper cover 210 is unlocked. Thereby, the user can open the outlet upper cover 210 outward. Similarly, the outlet lower cover 220 housed inside the outlet upper cover 210 can also be opened outward. In this state, the user can pull out the plug 102 of the charging cord 101 from the insertion port 201 a of the outlet 201. After charging, the plug 102 of the charging cord 101 is not inserted into the outlet 201a of the outlet 201, and the outlet lower cover 220 and the outlet upper cover 210 are closed.

  According to the present embodiment, the outlet cover 202 is locked during charging. For this reason, even if a force is applied from the outside, the outlet cover 202 does not open. Further, the flange portion 105 having a diameter larger than the opening hole 230 formed by the outlet lower cover 220 and the outlet upper cover 210 is the inside of the outlet cover 202. For this reason, even if the charging cord 101 is pulled, the flange portion 105 does not come out of the opening hole 230 and the connection state between the plug 102 and the outlet 201 can be maintained. Therefore, it is possible to prevent the charging cord 101 from being pulled out as much as possible during charging.

  In addition, the outlet cover 202 can be locked by closing the outlet lower cover 220 and the outlet upper cover 210 after charging. For this reason, it can prevent as much as possible that the user who does not have a regular key uses the charging stand 200 without permission.

  Furthermore, a wire layer 108 made of metal is formed on the surface of the charging cord 101. For this reason, it is possible to prevent the vehicle from moving without permission by cutting the charging cord 101 during charging as much as possible.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It can implement with a various form.

  In the above embodiment, an example in which hook portions (51, 52, etc.) around which a charging cord is wound is provided at two or four locations has been described, but application of the present invention is not limited to this. That is, it is good also as a structure which provided the hook part in three places, and good also as a structure provided in five or more places.

  In addition, if the hook portion can be attached to the vehicle body frame directly or via a stay or the like at a position where the side is covered by the vehicle body cover, the cord storage portion is not limited to the position shown in the above embodiment, but at other positions. It is good also as a provided structure.

  In the above-described embodiment, the example in which the present invention is applied to the electric motorcycle that travels by rotating the rear wheel 25 only by the power of the electric motor 31 has been described, but the application of the present invention is not limited thereto. In other words, the present invention can also be applied to a hybrid straddle-type vehicle that travels by driving the rear wheels to rotate by combining two powers of the power generated by the internal combustion engine and the power of the electric motor.

  More specifically, the “motor” of the present invention is a concept including an electric motor that obtains power only by electricity, a hybrid power unit that combines this electric motor and an internal combustion engine, and the like. That is, the motor is not particularly limited as long as it is a power unit that obtains all or part of the power by an electric motor.

  Further, the saddle riding type vehicle according to the present invention can be applied to a motorcycle type, a cub type, and a scooter type as in the above embodiment.
