ある。However, in such a conventional technique, since the coupling structure utilizing the fitting of the groove and the projection is used, when the axial crushing force is applied to one member, The fitting portion between the groove and the protrusion may impede the stable collapse mode of the member. That is, when the axial crushing force is applied to one end of the member, the member is deformed into a bellows shape that repeats regular unevenness as an ideal crushing mode that most effectively absorbs the energy of the axial crushing force. However, this ideal deformation may be hindered by the fitting portion between the groove and the projection as described above.

The end portion of the first member A originally has a convex portion 13 and a concave portion 14.
It causes bellows deformation to repeat regularly. FIG.

モードを邪魔しない。 Orientation of the extruded material 3 with respect to the first member A (see FIG.
1, see FIG. 4): when the axial crushing force F is applied to the end of the first member A, the end of the first member A has a convex portion 13 and a concave portion 14.
However, since the extrusion direction α of the extruded material 3 is orthogonal to the axial direction β of the first member A, the extruded material 3 is deformed in the axial direction β of the first member A. It is easily crushed, and the extruded material 3 does not interfere with the ideal crush mode of the first member A.

交させたものである。That is, if the extruding direction α of the extruded material 3 is matched with the axial direction β of the first member A, the vertical surface portions 4 and 5 and the inclined surface portion 6 of the extruded material 3 are in a state along the axial direction β. ,
The axial crushing force F is received within the planes of the vertical surface portions 4 and 5 and the inclined surface portion 6. Therefore, the extruded material 3 is less likely to be crushed, and the ideal collapse mode of the first member A as described above is hindered. Particularly, in this embodiment, the X-shaped rib 10 is also formed in the extruded material 3, and the rib 10 suppresses the out-of-plane deformation of the vertical surface portions 4 and 5, so that the extruded material 3 is less likely to be crushed. Therefore, the first member A cannot maintain the ideal crush mode in which the convex portion 13 and the concave portion 14 are repeated. In the present embodiment, in order to avoid such a state, the extrusion direction α of the extruded material 3 is orthogonal to the axial direction β of the first member A.

When the protrusions 13 and the recesses 14 on the lower surface 1 of the member A are joined to the vertices, the protrusions 13 are joined at the joining points with the extrusion material 3.
The apex of the concave portion 14 is pushed or pulled, so that ideal uneven deformation is not exhibited.

(See FIG. 4): The lateral surface portion 8 of the extruded material 3 has the extruded material 3 first.
Although it is a portion that produces a reaction force when the member A is deformed along the axial direction β, the convex portion 13 of the first member A is formed on the lateral surface portion 8.
Since the concave portion 9 corresponding to is formed, the lateral surface portion 8 easily collapses along the axial direction β of the first member A. Moreover, since the convex portion 13 of the first member A and the concave portion 9 of the lateral surface portion 8 correspond to each other and the convex portion 13 can enter the concave portion 9 at the time of crushing,
Even if the distance D (see FIG. 3) between the lower surface 1 and the lateral surface portion 8 is small, they do not interfere with each other, and the original ideal collapse mode of the first member A can be obtained.
