- a reinforcement serving as a reinforcing member is provided inside the side panel 1.
- a front pillar reinforcement 5 for increasing the rigidity of the front pillar 2 is provided inside the front pillar 2.
- a center pillar reinforcement 6 for increasing the rigidity of the center pillar portion 3 is provided inside the center pillar portion 3, and a side sill phosphorus for increasing the rigidity of the side sill portion 4 is provided inside the side sill portion 4.
- a force 7 is provided.
- the center pillar reinforcement 6 has an upper portion coupled to, for example, a front pillar reinforcement 5 forming the front pillar portion 2 and a lower portion thereof coupled to the side sill reinforcement 7.
- the center pillar reinforcement 6 is joined to the side sill reinforcement 7 by spot welding at a plurality of locations.
- the center pillar reinforcement 6 has a substantially U-shaped cross section, and connects the pair of width walls 6a, 6b extending in the vehicle width direction and the pair of width walls 6a, 6b extending in the vehicle front-rear direction. And front and rear walls 6c.
- a center pillar inner 8 is provided inside the center pillar reinforcement 6, and the center pillar reinforcement 6 is coupled to the side sill reinforcement 7 together with the center pillar inner 8.
- a convex reinforcing bead 10 protruding outside the vehicle (the side opposite to the center pillar inner 8) is provided.
- the reinforcing bead 10 is provided to increase the rigidity of the center pillar reinforcement 6.
- two reinforcing beads 10A and 10B are juxtaposed on the front and rear walls 6c of the center pillar reinforcement 6 in the front-rear direction of the vehicle.
- the reinforcing bead 10 (10A, 10B) extends upward from the vicinity of the lower end portion of the center pillar reinforcement 6, and the upper end side of the reinforcing bead 10 has a width wall 6a of the center pillar reinforcement 6; It extends toward the corner formed by 6b and the front and rear walls 6c.
- the reinforcing bead 10A provided on the vehicle front side is extended toward the corner 6d formed by the width wall 6a and the front and rear walls 6c on the vehicle front side, and is provided on the vehicle rear side.
- the bead 10B is extended toward the corner 6e formed by the width wall 6b and the front and rear walls 6c on the vehicle rear side.
- the upper end side of the reinforcing bead 10A is connected to the corner portion 6d
- the upper end side of the reinforcing bead 10B is connected to the corner portion 6e.
- the lower end side of the reinforcing bead 10 is formed without reaching the lower end of the center pillar reinforcement 6. And the lower end part of each reinforcement bead 10 is formed in the substantially semicircle in planar view.
- a convex bead 11 is also provided between the two reinforcing beads 10A and 10B.
- this bead 11 is provided not for enhancing the rigidity of the center pillar reinforcement 6 but for draining water, for example. Therefore, unlike the reinforcing bead 10, the bead 11 is continuously provided up to the lower end of the center pillar reinforcement 6.
- the spot welding spot for joining the center pillar reinforcement 6 and the side sill reinforcement 7 to the region including the periphery of the lower end of each reinforcing bead 10 formed in a semicircular shape as described above ( Welded portions) 21 to 32 are arranged. Further, in the periphery of the lower end portion of each reinforcing bead 10 formed in a semicircular shape, spot welding spots 21 to 28 formed on the center pillar reinforcement 6 are substantially uniform from the ridge line of the reinforcing bead 10. It is arranged so as to be a great distance.
- the hit points 21 to 24 arranged around the reinforcing bead 10A are formed so as to have a substantially uniform distance L1 from the ridge line of the reinforcing bead 10A, and the hit points arranged around the reinforcing bead 10B. 25 to 28 are formed to have a substantially uniform distance L2 from the ridge line of the reinforcing bead 10B.
- the ridge line of the reinforcing bead 10 is, in other words, a line along the peripheral edge of the top surface of the reinforcing bead 10 having a convex shape. Further, the distance L1 from the ridge line of the reinforcing bead 10A to each hitting point 21 to 24 and the distance L2 from the reinforcing bead 10B to each hitting point 25 to 28 may be the same or different.
- hit points 21 to 24 provided corresponding to the reinforcing beads 10A are arranged at substantially equal intervals.
- the hit points 25 to 28 provided corresponding to the reinforcing beads 10B are also arranged at substantially equal intervals.
- an impact applied to the coupling portion between the center pillar reinforcement 6 and the side sill reinforcement 7 at the time of a side collision or the like is applied from each spot welding spot to the reinforcing bead. 10 is transmitted substantially uniformly. That is, it is possible to suppress a large force from being locally transmitted to the reinforcing bead 10. Thereby, the deformation
- the hit points 21 to 24 provided corresponding to the lower end portion of the reinforcing bead 10A are arranged at substantially equal intervals, and the hit points 25 to 25 provided corresponding to the lower end portion of the reinforcing bead 10B are set. Since 28 is also arranged at substantially equal intervals, the force is evenly transmitted from the hit points 21 to 24 to the entire reinforcing bead 10A, and the force is uniformly transmitted from the hit points 25 to 28 to the entire reinforcing bead 10B. . Therefore, the deformation of the center pillar reinforcement 6 can be suppressed.
- the upper end side of the reinforcing bead 10A is connected to the corner portion 6d
- the upper end side of the reinforcing bead 10B is connected to the corner portion 6e.
- the shape of the reinforcing bead formed in the center pillar reinforcement is not particularly limited.
- the lower end portion of the reinforcing bead is formed in a substantially semicircular shape, but of course, other shapes may be used.
- the spot welding spot formed around the reinforcing bead is arranged at a substantially uniform distance from the ridge line of the reinforcing bead.
- the spot welding spots formed around the reinforcing beads are arranged at substantially equal intervals, but the intervals need not necessarily be equal.
