- the pillar 20 that extends in the vertical direction of the vehicle and is joined to the rocker 10 and the roof rail 40, and connects both, improves the rigidity of the entire body by connecting the roof and the floor 5. As a result, when the vehicle is traveling, deformation such as bending of the body due to a load generated during traveling is minimized, and stability during traveling is ensured.
- the load generated during the traveling of the vehicle is mainly received by the frame material 1 having such strength, but the vehicle may receive a load other than the load acting on the body by the normal traveling.
- a load due to the energy of the collision acts on the frame material 1.
- the frame material 1 when the load due to the energy of the collision acts on the frame material 1, in many cases, a load larger than the load that acts on the frame material 1 during normal traveling of the vehicle acts. For this reason, the frame material 1 may be deformed by this large load.
- FIG. 9 is an explanatory view showing a state where the locker is deformed.
- the frame material 1 may be deformed at a portion where the large load acts or a portion where the stress becomes large, but the large load acts on the frame material 1 in this way.
- a case where a large load acts on the joint region 30 between the pillar 20 and the rocker 10 will be described.
- the pillar 20 and the rocker 10 are joined by spot-welding the lower end portion of the pillar 20 to the rocker 10, but the opposite end of the pillar 20 is joined to the roof rail 40.
- the pillar 20 is provided as a member for ensuring the strength of the vehicle body, and a relatively large load is likely to be applied even during normal traveling. When this occurs, a larger load is likely to act on the joint region 30 between the rocker 10 and the pillar 20.
- a large load acts in the front-rear direction of the vehicle due to the collision of the vehicle.
- a large load acts in the front-rear direction of the vehicle due to the collision of the vehicle.
- a large load is input or a large load in the width direction of the vehicle is input to the pillar 20 due to a side collision of the vehicle, so that at least a part of the pillar 20 is pulled up from the rocker 10 with a large force.
- the load is easily transmitted along the ridge line 24 formed on the pillar 20, and therefore, in the joint region 30 between the pillar 20 and the rocker 10,
- a large load is likely to act on the extended line of the ridge line 24 of the pillar 20.
- the rocker 10 may be deformed by a large load acting in the vicinity of the joining region 30.
- a patch member 50 is provided in a joint region 30 of the rocker 10 with the pillar 20.
- the portion where the patch member 50 is provided is higher in strength than the surrounding portion of the rocker 10. Therefore, the portion where the patch member 50 is provided is difficult to deform even when a large load is applied to the rocker 10.
- the portion of the rocker 10 where the patch member 50 is not provided is not increased in strength by the patch member 50, so that stress is easily increased when a load is input.
- stress concentration is likely to occur at the boundary portion with the portion where the patch member 50 is provided, that is, at the portion where the edge portion of the patch member 50 is located, since the stress changes abruptly.
- the patch member 50 in the rocker 10 is provided. Stress concentration is likely to occur at the boundary portion between the portion that is present and the portion that is not provided. Therefore, as shown in FIG. 9, the rocker 10 is easily deformed in the vicinity of the patch member 50 in a portion where the patch member 50 is not provided, and the bent portion 70 is easily generated in this portion.

- the patch member 50 is formed in a substantially L shape when viewed in the front-rear direction of the vehicle, the strength of the patch member 50 is increased in both the vertical direction and the width direction of the vehicle. 10, the strength of the portion where the patch member 50 is disposed is high. For this reason, the rocker 10 is more difficult to deform in the portion where the patch member 50 is provided, and the bent portion 70 is generated by being deformed in the vicinity of the portion where the patch member 50 is provided.
- the patch member 50 is not disposed on the lower side of the rocker 10 but is disposed closer to the upper portion of the rocker 10. For this reason, when a large load is input at a portion where the joint region 30 between the rocker 10 and the pillar 20 is located in the front-rear direction of the vehicle, the lower side of the rocker 10 is easily deformed.
- the pillar 20 is joined to a portion closer to the upper side than the locker 10, and is provided to extend above the locker 10. For this reason, when a large load is input to the rocker 10, the region opposite to the side where the pillar 20 extends from the rocker 10 is easily deformed at the portion where the joining region 30 in the front-rear direction of the rocker 10 is located. That is, the position near the upper part of the rocker 10, which is the region where the welded part 62 is located, is difficult to deform, and the fracture of the welded part 62 is suppressed.
- the patch member 50 is formed with a notch 52, and the notch 52 is formed so as to be located at a part of the welded part 62. For this reason, the patch member 50 is in a state of being disposed at a position corresponding to the periphery of the welded portion 62.
- the load acting near the welded portion 62 is concentrated near the portion where the edge of the patch member 50 is located.
- the stress at the part increases. Therefore, the rocker 10 is located near the portion where the edge of the patch member 50 located around the welded portion 62 is located, that is, the edge of the notch 52 formed in the patch member 50. It becomes easy to deform near the part where the part is located. For this reason, the rocker 10 is hardly deformed on the welded portion 62, and the fracture of the welded portion 62 is suppressed.
- the welded portion 62 where the notch 52 is located is a welded portion 62 in which stress is excessive when a load is applied to the joining region 30, fracture occurs when a load is applied to the joining region 30.
- the notch 52 is located at a portion where the welded portion 62 is located, excessive stress is dispersed around the welded portion 62.

- the patch member 50 that deforms the rocker 10 in a desired state when a load is applied to the joint region 30 is provided in the joint region 30 between the rocker 10 and the pillar 20. Even when a large load is applied to 30, the rocker 10 can be prevented from being deformed at the portion where the weld 62 is located. Thereby, it can suppress that the welded part 62 fracture
- the patch member 50 is disposed in a region where the length in the front-rear direction of the vehicle is slightly longer than a region where all the welds 62 are located. Thereby, the patch member 50 does not simply reinforce the joining region 30, but can generate a difference in strength between the portion where the weld 62 is located and the other portions. Therefore, when a large load is applied to the joining region 30, the rocker 10 can be deformed at a portion other than the portion where the welded portion 62 is located, and the welded portion 62 can be prevented from breaking. As a result, even when a large load acts on the joint region 30 between the rocker 10 and the pillar 20, the joint can be maintained.
- the notch 52 formed in the patch member 50 is provided in a portion where a part of the welded portion 62 is located. That is, since the patch member 50 is provided excluding the periphery of the welded portion 62, when a large load is applied to the joining region 30, the edge of the notch 52 is located at a portion where the welded portion 62 is located. The rocker 10 can be easily deformed near the portion where the portion is located. Thereby, it can suppress that the welded part 62 fracture
- the welded portion 62 where the notch 52 is positioned is a welded portion 62 in which a stress is excessive when a load is applied to the joining region 30, the excessive stress is dispersed around the welded portion 62.
- the deformation of the rocker 10 due to excessive stress is likely to occur near the portion where the edge of the notch 52 is located.
- the welding part 62 in which the stress tends to be excessive is more reliably suppressed from breaking.
- the joining can be more reliably maintained.
- the patch member 50 is formed in a substantially L shape, is formed in a shape having high strength and is disposed in the joining region 30, the portion of the joining region 30 where the patch member 50 is provided.

Therefore, even when a large load is applied to the joining region 30, it is possible to more reliably suppress the rocker 10 from being deformed at the portion where the welded portion 62 is located and the welded portion 62 being broken. As a result, even when a large load is applied to the joining region 30 between the rocker 10 and the pillar 20, the joining can be more reliably maintained.
- the patch member 50 is disposed near the upper part of the rocker 10, the patch member 50 is provided without including a lower region which is a region opposite to the side where the pillar 20 extends in the rocker 10. For this reason, when a large load is input to the rocker 10 due to a large load being input to the joining region 30, the rocker 10 is easily deformed on the lower side where the patch member 50 is not provided. Therefore, even when a large load is input to the joining region 30, it is possible to make it difficult for the position near the upper portion of the rocker 10, which is the region on which the pillar 20 extends, to be deformed. Breakage of the welded portion 62 to be joined can be more reliably suppressed. As a result, even when a large load is applied to the joining region 30 between the rocker 10 and the pillar 20, the joining can be more reliably maintained.
