A power receiving connector includes a connection port to connect a power supply connector in a first direction. A grasped portion for an operator to grasp is provided near the power receiving connector. At least a portion of the grasped portion is located in a second direction orthogonal or substantially orthogonal to the first direction from the power receiving connector when the connection port of the power receiving connector is viewed in the first direction. When the power supply connector provided in a battery charger is connected to the power receiving connector provided in a vehicle body and the power supply connector is pulled out from the power receiving connector, instability of the attitude of the vehicle body is reduced or prevented.
