An inlet is an inlet to which a charging connector is connected when charging a power storage device mounted in a hybrid vehicle from an external power supply. The inlet includes a cylindrical guide wall that guides the charging connector to be connected to the inlet; a flange portion that is provided in a plate shape on an outer periphery of the guide wall, and is fixed to the vehicle; a lever retaining portion that is provided on the outer periphery of the guide wall, and retains the charging connector; and a recessed portion that is provided in a position overlapping with the lever retaining portion when viewed from a connecting direction of the charging connector, and is recessed toward the connecting direction of the charging connector from the flange portion. This kind of structure provides an inlet in which a protruding length from the vehicle side is reduced.
