Abstract

A vehicular structure includes: a first member formed in a tubular shape and having protrusions on an outer periphery thereof; and a second member formed in a tubular shape and having a locking wall with a hole in which the first member is inserted. The first member is joined to the second member such that a portion of the first member that is inserted in the hole of the second member is expanded, and the protrusions are in contact with the locking wall of the second member.

Claims (27)

1. A vehicular structure comprising:

a first member formed in a tubular shape and having a protrusion on an outer periphery thereof; and

a second member formed in a tubular shape and having a locking wall with a hole in which the first member is inserted,

wherein the first member is expanded at a portion thereof inserted in the hole of the second member and joined to the second member, and

wherein the protrusion is in contact with the locking wall of the second member.

2. The vehicular structure according to claim 1 , wherein the hole penetrates the locking wall in a direction intersecting a longitudinal direction of the second member, and

wherein the protrusion protrudes in the longitudinal direction.

wherein a material of the first member is different from a material of the second member.

8. The vehicular structure according to claim 7 ,

wherein the first member is made of an aluminum material, and the second member is made of a steel material.

9. The vehicular structure according to claim 2 ,

wherein the first member is a bumper stay for a vehicle, and the second member is a bumper beam for a vehicle.

10. The vehicular structure according to claim 2 ,

wherein each of the first member and the second member is made of an aluminum material.
