The invention provides a vehicle body lower portion structure which can improve air mechanical performance and can restrain a guide plate from excessively unfolding or falling off. The vehicle body lower part structure comprises a guide plate which is arranged on a vehicle body of a vehicle and can move between a storage position covering the lower part of the vehicle body and an expansion position protruding downwards. The vehicle body lower structure further comprises a hook component arranged on the upper surface of the flow guide plate, the hook component is buckled on a buckling part of the vehicle body under the condition that the flow guide plate is located at the unfolding position, and the hook component is buckled on a buckling part of the vehicle body under the condition that the flow guide plate is located at the storage position. And the hook component is separated from the buckle part of the vehicle body.
