(Problems to be solved by the invention) However, in the above conventional one, in the case where the rear floor panel is provided with a bead portion for improving the cross-sectional rigidity and the barrier panel is joined to the bead portion surface with a closed space, In a wheel drive vehicle, the propeller shaft floor tunnel penetrates through the center of the vehicle's rear floor panel, so joining the barrier panel does not allow escape at the center of the rear floor panel through which this floor tunnel penetrates to prevent deterioration due to vibration. Although necessary, this escape rather reduces the rigidity of the barrier panel and causes the rear floor panel to resonate due to the vibration of the propeller shaft, causing a muffled noise during driving, which leads to a reduction in quietness. It is a thing. In the case of No. 59-70880, the cross member is fixed to the rear of the belt anchorage part of the rear floor panel, and the cross member and the rear floor panel are joined in a closed space. In the case of a vehicle, the propeller shaft floor tunnel penetrates the center of the vehicle's rear floor panel, so a large closed space cannot be secured to improve rigidity, and vibrations due to the propeller shaft cannot be sufficiently prevented. There is. Therefore, this invention is intended to improve the drawbacks of the above-mentioned conventional ones, and to effectively prevent the vibration from the propeller shaft in a limited space.

(Means for solving the problem) Therefore, in a rear floor panel having a reinforcing bead portion in the front-rear direction of the vehicle body, a flat surface is provided on the front end portion of the reinforcing bead portion of the portion corresponding to the floor tunnel through which the propeller shaft penetrates. Formed, forming a closed space between the flat surface and the barrier panel, providing the barrier panel so as to be joined to the surface of the protruding portion of the reinforcing bead, and joining the front end edge of this barrier panel to the rear floor panel. It will be.

(Operation) Since the barrier panel is configured so as to closely adhere to the projecting surface of the rear floor panel, there is no escape between the barrier panel and the floor panel, and the propeller shaft is used. Since it does not resonate due to vibration, and the barrier panel edge is joined to the floor panel so as to form a closed space between the floor panel and the barrier floor at the front end portion thereof,
The cross-sectional constant can be increased to improve the rigidity.

(Embodiment) The invention will be further described with reference to an embodiment shown in the drawings. (1)
Is an underfloor of an automobile according to an embodiment of the present invention. The underfloor (1) of this automobile is provided with a floor tunnel (2) through which a propeller shaft penetrates in the center and a load on an occupant's board is provided on the surface. To cope with this, a rear floor panel (3) having a plurality of reinforcing bead portions (4) arranged in the vehicle front-rear direction, and a barrier panel (5) integrally joined to the rear floor panel (3). Is. At this time, in the rear floor panel (3) having the reinforcing bead portion (4), particularly in the portion corresponding to the floor tunnel (2) through which the propeller shaft penetrates, the front end portion of the reinforcing bead portion (4) is provided. Flat surface (1
1) is formed and the front end of the bar (6) of the barrier panel (5) forms a closed space (8) between the rear floor panel (3) and the barrier panel (5) on the flat surface (11). It is made by joining the edges. Therefore, at the portion corresponding to the floor tunnel (2) through which the propeller shaft penetrates, since it is in close contact with and joined to the projecting portion (10), it is difficult to resonate due to the vibration from the propeller shaft and the flat surface (11) In the upper part, the bar (6) of the barrier panel (5) so as to form a closed space between the rear floor panel (3) and the barrier panel (5).
Therefore, the closed space (8) for improving the rigidity of the rear floor panel (3) can be made large. The reinforcing bead portion (4) other than a person who communicates with the flat surface (11) arranged on the rear floor panel (3).
Extend to the bent part (7) of the rear floor panel (3),
Furthermore, by providing the bead portion (9) also on the bar (6) of the barrier panel (5), the electrodeposition liquid can be easily released during coating.
