Vehicle charging system and power receiving fitting body

A vehicle charging system comprising:

• a power supply device including a power supply fitting body and provided in a stop space of a vehicle;
• and
• a power receiving fitting body that is provided on a bottom of the vehicle and is able to be fitted to and removed from the power supply fitting body in a horizontal insertion/removal direction extending horizontally, wherein
• the power receiving fitting body includes a power receiving terminal electrically connected to a battery provided in the vehicle, a power receiving terminal holding part that holds the power receiving terminal, and an opposite space forming part that is arranged adjacent to the power receiving terminal holding part in the horizontal insertion/removal direction and forms an opposite space facing the power receiving terminal,
• the power supply fitting body includes a power supply terminal electrically connected to a charging device provided outside the vehicle,
• the power supply device includes at least a horizontal insertion/removal direction movement part that moves the power supply fitting body in the horizontal insertion/removal direction, and
• when the power supply fitting body is located in the opposite space and the power supply terminal and the power receiving terminal are in an opposite state in which the power supply terminal and the power receiving terminal are opposite to each other in the horizontal insertion/removal direction, the horizontal insertion/removal direction movement part causes the power receiving fitting body and the power supply fitting body to be fitted to each other by moving the power supply fitting body toward the power receiving fitting body in the horizontal insertion/removal direction, and electrically connects the battery and the charging device by bringing the power receiving terminal and the power supply terminal into contact with each other.
