Abstract

A side member distal end structure includes: a side member distal end part and a lid member disposed forward of a distal end of the side member distal end part. The side member distal end part includes: a closed section part whose sectional shape orthogonal to the vehicle front-rear direction has a closed section structure; and a flange part in which a first panel and a second panel are joined to each other, the flange part being disposed outer than the closed section part and extending along the vehicle front-rear direction. The lid member includes a side plate part partially joined to an outer surface which is a part of the closed section part and is disposed forward of the flange part. In the vehicle front-rear direction, a plate surface of the side plate part faces the flange part.

Claims

1. A side member distal end structure, comprising:

a side member distal end part; and

a lid member forward of a distal end of the side member distal end part in a vehicle front-rear direction, wherein

the side member distal end part includes a closed section part whose sectional shape orthogonal to the vehicle front-rear direction has a closed section structure; and

a flange part in which a first panel and a second panel, the first panel and the second panel constructing at least a part of the closed section part, are joined to each other, the flange part being outward from the closed section part in a vehicle width direction and extending along the vehicle front-rear direction,

the lid member includes a side plate part, the side plate part being partially joined to an outer surface, the outer surface being a part of the closed section part and being forward of the flange part in the vehicle front-rear direction,

in the vehicle front-rear direction, a plate surface of the side plate part faces the flange part, and

the plate surface facing the flange part includes a recessed part recessed toward a front of the vehicle in the vehicle front-rear direction, the recessed part being along an erection direction of the flange part.

2. The side member distal end structure according to claim 1, wherein

a facing part of the side plate part, the facing part facing the flange part in the vehicle front-rear direction, includes a joining part and an upright part, the joining part being joined to the outer surface of the closed section part, the upright part being connected with the joining part through a bent part, and the upright part extending along the erection direction of the flange part.

3. The side member distal end structure according to claim 2, wherein

a dimension of the upright part is larger than a dimension of the bent part in a flange width direction, the flange width direction being perpendicular to both of the vehicle front-rear direction and the erection direction of the flange part.

4. The side member distal end structure according to claim 1, wherein

the lid member faces the closed section part in the vehicle front-rear direction to close an opening on a distal end of the closed section part in the vehicle front-rear direction, and

the lid member includes a fastening part fastening a bumper reinforcement and the lid member to each other, the bumper reinforcement being along the vehicle width direction.

5. The side member distal end structure according to claim 2, wherein

the plate surface facing the flange part is included in the upright part.

6. A side member distal end structure, comprising:

a side member distal end part; and

a lid member forward of a distal end of the side member distal end part in a vehicle front-rear direction, wherein

the side member distal end part includes a closed section part whose sectional shape orthogonal to the vehicle front-rear direction has a closed section structure; and

a flange part in which a first panel and a second panel, the first panel and the second panel constructing at least a part of the closed section part, are joined to each other, the flange part being outward from the closed section part in a vehicle width direction and extending along the vehicle front-rear direction,

the lid member includes a top plate part, an upper plate part, a lower plate part, and an upper bent flange part upwardly extending from the top plate part, the upper plate part and the lower plate part being partially joined to an outer surface, the outer surface being a part of the closed section part and being forward of the flange part in the vehicle front-rear direction, and

in the vehicle front-rear direction, the upper bent flange part faces the flange part.

7. The side member distal end structure according to claim 6, wherein

the upper bent flange part is a first upper bent flange part and the lid member includes a second upper bent flange part, the first upper bent flange part and the second upper bent flange part being on respectively opposite outer sides of the closed section part.

8. The side member distal end structure according to claim 6, wherein

the upper bent flange part facing the flange part includes a recessed part recessed toward a front of the vehicle in the vehicle front-rear direction, the recessed part being along an erection direction of the flange part.

9. The side member distal end structure according to claim 6, wherein

the upper plate part is a joining part being joined to the outer surface of the closed section part, and

the upper bent flange part is an upright part being connected with the joining part through a bent part, and the upright part extends along an erection direction of the flange part.

10. The side member distal end structure according to claim 9, wherein

a dimension of the upright part is larger than a dimension of the bent part in a flange width direction, the flange width direction being perpendicular to both of the vehicle front-rear direction and the erection direction of the flange part.

11. The side member distal end structure according to claim 6 wherein

the lid member faces the closed section part in the vehicle front-rear direction to close an opening on a distal end of the closed section part in the vehicle front-rear direction, and

the lid member includes a fastening part fastening a bumper reinforcement and the lid member to each other, the bumper reinforcement being along the vehicle width direction.
