A vehicle-side connector (10) is connectable to a charging connector (1) for charging a battery in a vehicle and includes a housing (30) on the vehicle such that the charging connector (1) can fit therein from the front. Terminal fittings (11) connected respectively to wires (20P, 20S) are drawn out from the interior of the vehicle including the battery. Terminal accommodating chambers (40) are provided in the housing (30) and the respective terminal fittings (11) are inserted therein from behind. Each terminal fitting (11) is a round pin terminal (12) with a terminal connecting portion (13) on one end for connection to a charging terminal in the charging connector (1) and a wire connecting portion (14) on the other end to be crimped to an end of the wire (20P, 20S). The terminal connecting portion (13) is retained in the terminal accommodating chamber (40).
