Is a side sill that extends in the front-rear direction on the side surface of the vehicle body. The side sill 1 includes a sill inner panel 2, a sill outer panel 3, and a sill inner panel 2 and a sill outer panel 3.
It is composed of a reinforcement sill reinforcement panel 4 interposed between and, and the upper flange 2 of each panel.
A, 3a, 4a and the lower flanges 2b, 3b, 4b are welded to form a closed cross section. Side sill 1
A brace 5 that closes the closed cross section formed by the sill outer panel 3 and the sill reinforcement panel 4 is attached inside.

端の着座部付近に取り付けることが望ましい。The brace 5 suppresses deformation of the closed cross section of the side sill 1 due to vibration input to the vehicle body during traveling, and also enhances the rigidity of the side sill 1 by receiving an input in the vehicle width direction at the time of a side collision. When installing multiple brace 5 at intervals in the front-rear direction of the vehicle body,
In order to receive the force input to the passenger compartment side, it is desirable to install it near the end of the strength member such as the seat cross member and the second cross member. Also, the lower end of the center pillar as the space between the seat cross member and the second cross member. It is desirable to attach it near the seating part of.

ある。However, in such a conventional side sill reinforcing structure for an automobile, the brace is provided with a side sill against a small deformation within the elastic range of the vehicle body such as a vibration input to the vehicle body during traveling. Although it contributes to the improvement of vehicle body rigidity by suppressing the deformation of the closed cross section of the side sill, when the side sill collapses and deforms at the time of a large input at the time of a side collision, the brace is rather strong and difficult to deform, so the side sill Deformation is suppressed by braces, and as a result, energy can be absorbed only in a narrow range.

がるという問題もある。Further, when a plurality of braces 5 are mounted, if the braces are mounted near the lower end seating portion of the center pillar and near the end portion of the seat cross member, the distance between these two braces is short and the seat cross member of the side sill is short. The strength of the part near the edge is stronger than the strength of the part near the lower end of the center pillar, and if there is a brace, the side sill is less likely to deform, so excessive tensile stress may act on the side sill during a side collision, which is inevitable. In order to increase the distance between the braces, the brace must be attached to the rear of the vicinity of the end of the seat cross member. Therefore, there is also a problem that the brace cannot be attached near the end of the strength member, which is a desirable attachment position during normal traveling, and the degree of freedom in design is reduced.

形成する。In order to achieve the above object, in the invention according to claim 1, the closed cross section is substantially closed inside the side sill which is on the side surface of the vehicle body and which forms the closed cross section and extends in the longitudinal direction of the vehicle. In a side sill reinforcement structure for an automobile with a brace attached, an easily bendable portion that is easier to bend with respect to an input in the vehicle width direction than other portions is provided on a surface of the brace that extends in the vehicle width direction from an upper end to a lower end of the brace.

する。For a large input in the vehicle width direction at the time of a side collision,
By bending the easily bendable portion, the surface of the brace in the vehicle width direction is crushed, so that collision energy can be effectively absorbed. According to the second aspect of the present invention, a brace that substantially closes the closed cross section is formed inside the side sill that forms a closed cross section on the side surface of the vehicle body and that extends in the front-rear direction of the vehicle. In a side sill reinforcement structure for an automobile, which is attached to the vicinity of each portion at an interval in the front-rear direction of the vehicle body, a surface extending in the vehicle width direction of the brace attached to the vicinity of the end of the seat cross member of the brace is compared to other portions. An easily bendable portion that is easily bent with respect to an input in the vehicle width direction is formed from the upper end to the lower end of the brace.

It functions to suppress the deformation of the closed cross section of the side sill 1 during normal traveling, but as shown by the arrow in FIG. 5, when a large input in the vehicle width direction is received at the time of a side collision, the easily bendable portion 16 bends,
Since the surface in the vehicle width direction is crushed as a whole of the brace 15,
The collision energy can be effectively absorbed. Further, the brace 1 mounted near the end of the seat cross member where the distance is short and the strength is difficult to balance, such as near the rear seat of the lower end of the center pillar 8 and the end of the seat cross member 6.
By forming the easily bendable portion 16 in 5, it is possible to balance the strength with the surroundings. That is, as shown in FIG. 5, the brace 15 attached near the end of the seat cross member bends at the time of a side collision, so that excessive tensile stress does not act on the side sill 1.
