The intermediate portion 24C in the vertical direction of the inner 24 has a V shape extending toward the upper side in the vehicle width direction.

  As shown in FIG. 2, a reinforcing flange 22 </ b> D is continuously formed on the outer peripheral edge portion of the hook bracket outer 22 excluding the upper end edge portion toward the outer side in the vehicle width direction. A reinforcing bead 32 that protrudes outward in the vehicle width direction is formed continuously from the hook hole 30 to the lower portion of the upper end 22B of the hook bracket outer 22 at the center in the front-rear direction. Similarly, a flange 24D for reinforcement is continuously formed toward the inner side in the vehicle width direction on the outer peripheral edge portion excluding the upper edge of the hook bracket inner 24, and the center portion in the front-rear direction of the hook bracket inner 24 is also provided. A reinforcing bead 34 that protrudes inward in the vehicle width direction is continuously formed from the hook hole 30 to the lower portion of the upper end portion 24B of the hook bracket inner 24.

  Therefore, in the vehicle body rear part structure described above, as shown in FIG. 4, for example, when the vehicle is towing and running (running in a state where the marine transportation vehicle is towed), the lower end 20A of the lash hook bracket 20 is provided. When a load in the vehicle width direction (arrow F1 in FIG. 4) is input, load in the vertical direction (arrows F2 and F3 in FIG. 4) is applied to the hook bracket outer 22 and the hook bracket inner 24 of the lash hook bracket 20. ) Acts.

  Next, the operation and effect of this embodiment will be described.

  In an automobile body to which the vehicle body rear structure having the above-described configuration is applied, for example, as shown in FIG. 4, a load in the vehicle width direction (arrow F <b> 1 in FIG. 4) is applied to the lower end portion 20 </ b> A of the securing hook bracket 20 while the vehicle is towing. ) Is applied to the hook bracket outer 22 and the hook bracket inner 24 of the lash hook bracket 20 in the vertical direction (arrows F2 and F3 in FIG. 4). For this reason, a twisting load (arrow F4 in FIG. 4) acts on the rear side member 10 through the hook bracket outer 22 and the hook bracket inner 24 about the axis 10C along the front-rear direction.

  At this time, in this embodiment, the rear end portion of the rear side member 10 is formed by the vehicle width direction inner rear wall portion 12F and the vehicle width direction outer rear wall portion 12G at the rear end of the rear side member main body 12 constituting the rear side member 10. A rear wall portion for closing the cross section of the rear side member 10 is difficult to be deformed by the rear wall portion (bulk head).

  Supplementally, the front end part 12H of the vehicle width direction inner rear wall part 12F and the front end part 12J of the vehicle width direction outer rear wall part 12G overlap each other from the vehicle longitudinal direction, and spot welding is performed at two or more points on the upper and lower sides. They are connected to each other by (welding point X). For this reason, since the twisting load (arrow F4 in FIG. 4) is received in the shearing direction at the welding point X, it is more advantageous than the case of receiving the load in the peeling direction (it is difficult to peel off).

  For this reason, when the load F1 is input to the rear side member 10 from the lashing hook bracket 20, the cross-sectional deformation of the rear side member 10 can be prevented or suppressed. As a result, the out-of-plane deformation (deformation in the longitudinal direction of the vehicle body) of the flanges 16G, 16H, 16J of the rear side member extension 16 caused by the cross-sectional deformation of the rear side member 10 can be prevented or suppressed. It is possible to prevent or suppress damage such as peeling and deformation at the spot welding spot.

  Note that the rear side member 12 is configured such that the rear end (rear wall portion) of the rear side member main body 12 is set on the rear side of the vehicle body relative to the attachment position of the lashing hook bracket 20 and is provided near the lower back panel 14. It is possible to more effectively prevent or suppress damage to the joint portion between the flanges 16G, 16H, and 16J of the rear side member extension 16 and the vehicle body front side surface 14A of the lower back panel 14 that are generated by the cross-sectional deformation of 10.

  Further, in the present embodiment, the cross-sectional deformation of the rear side member 10 can be more effectively prevented or suppressed as compared with a configuration in which a bulkhead as another member is attached to the rear end portion of the rear side member main body 12.

  Supplementally, when a bulkhead of another member is attached to the rear end portion of the rear side member main body 12, the flange formed by bending the end portion of the bulkhead is joined to the side surface of the rear side member by spot welding. It becomes composition. For this reason, it becomes the structure which suppresses the cross-sectional deformation of the rear side member main body 12 with the flange of a bulkhead, and cannot prevent or suppress the cross-sectional deformation of the rear side member 10 effectively.

  In the present embodiment, the rear side member 10 is composed of two parts, a rear side member main body 12 and a rear side member extension 16. Therefore, by reinforcing only the rear side member extension 16, it is possible to reinforce the rear end portion of the rear side member 10 that requires rigidity and strength. For this reason, compared with the case where the rear end part of the rear side member 10 is reinforced by adding a bulkhead or reinforcement as another member, an increase in the number of parts can be suppressed.

  Further, when the rear side member 10 is a single member, the connecting flange with the lower back panel 14 cannot be made vertical in a side view due to restrictions in the die-cutting direction when the rear side member 10 is molded. This is a disadvantageous structure for peeling of the part. On the other hand, in the present embodiment, the rear side member 10 is composed of two parts, that is, the rear side member main body 12 and the rear side member extension 16, so that the rear side member extension 16 is less restricted in the mold release direction during molding. . For this reason, a design freedom increases with respect to the angle of the coupling flange with the lower back panel 14, and it can make it a perpendicular direction in a side view. As a result, the striking portion between the lower back panel 14 and the coupling flange can be configured to be advantageous for peeling (a configuration that is difficult to peel).

  In the present embodiment, the rear side member extension 16 is extended to the front side of the vehicle body, and the overlapping portion with the rear side member main body 12 is enlarged, so that the rigidity and the rear side member 10 can be increased without increasing the number of reinforcing parts. Strength can be increased.
