Abstract
In a vehicle side body structure, when a force that deforms a side door inward in a vehicle width direction acts on the side door, a second engagement section enters a clearance in the vehicle width direction of the side door, a first engagement section and the second engagement section respectively engage with a first engaged section and a second engaged section, and an engagement structure bent with the first engagement section serving as a fulcrum, so as to prevent the side door from flipping up.
Claims20
A vehicle side body structure comprising:
- a side door;
- and
- a side sill reinforcement that is provided on an inner side in a vehicle width direction of the side door and opposes a lower portion of the side door, wherein
- the side sill reinforcement includes an engaged structure having:
- a first engaged section that extends in a vehicle longitudinal direction;
- and
- a second engaged section at a distance from the first engaged section in a vertical direction and on an inner side in the vehicle width direction of the first engaged section with a clearance being provided from the first engaged section, and
- the side door includes
- an engagement structure
- having a first engagement section and a second engagement section on an outer side in the vehicle width direction of the side sill reinforcement, the first engagement section and the second engagement section extending in a closed state of the side door and existing away from each other on an outer side in the vehicle width direction and the inner side in the vehicle width direction, respectively, wherein
- the engagement structure includes:
- a second portion that extends in the vehicle width direction and includes the second engagement section on the inner side in the vehicle width direction,
- a first portion that extends upward from an outer end portion in the vehicle width direction of the second portion and cooperates with the second portion to form the first engagement section on a boundary between the first portion and the second portion, and
- a third portion that is integrally coupled to an upper end of the first portion and extends inward in the vehicle width direction from the upper end of the first portion, the first, second, and third portions thereby forming a channel shape, wherein
- the distance in the vertical direction between the first engaged section and the second engaged section is configured to allow the second engagement section to enter therein into the clearance, and
- the engagement structure is bent with the first engagement section as a fulcrum such that an inner angle between the first portion and the second portion is reduced to resist the second portion from being pulled out of the clearance.
