Therefore, by setting the direction indicated by the terminal 2a of the charging mark 2 to the right, the external power source 80 is disposed on the left side of the battery 11 and the vehicle 101, and the flow of electricity flows from the external power source 80 on the left side to the right battery 11 and the vehicle 101. The user can easily recall the situation toward.
- the direction indicated by the terminal 3a of the discharge mark 3 is leftward, the battery 11 and the vehicle 101 as the power source are arranged on the left side of the electric device 60, and the flow of electricity is from the left battery 11 and the vehicle 101 to the right side. The user can easily recall the situation toward the electrical device 60.
- the user can easily recall the situation where the flow of electricity continues from the left side to the right side.
- each of the charge mark 2 and the discharge mark 3 simulates a plug shape having the terminals 2a and 3a, and the charge mark 2 and the discharge mark 3 are By reversing the directions indicated by the terminals 2a and 3a, the direction in which the charging plug 71 is inserted toward the vehicle 101 is opposite to the direction in which the outlet plug 61 of the electric device 60 is inserted toward the vehicle.
- the situation can be easily recalled by the user. Therefore, the user can clearly determine that the battery 11 is being charged when looking at the charge mark 2 and that the battery 11 is being discharged from the battery 11 when looking at the discharge mark 3. It is possible to prevent misunderstanding whether the battery 11 is being charged or whether the battery 11 is being discharged from the electric device 60.
- the charging mark 2 having the right-facing terminal 2a is displayed on the left side
