As the door approaches the inner panel 14, the deformed portion approaches the bottom of the substantially conical shape and the total cross-sectional area increases, so the load bearing capacity increases, and the load bearing capacity gradually increases as shown in FIG. It becomes a load characteristic.

参照）と比べ大きく変化しない。Therefore, regardless of the direction of the applied load,
The load bearing capacity of the other energy absorbing portion 34 becomes larger than the load bearing capacity of the adjacent one energy absorbing portion 34. As described above, by mixing the energy absorbing portion 34 that is easily deformed and the energy absorbing portion 34 that is not easily deformed depending on the input direction of the load, the load resistance of each energy absorbing portion 34 cancels each other out when the load is applied. , The energy can be efficiently absorbed against the load from each direction.
Therefore, the load characteristic when the load acts from the tilt direction is the load characteristic when the load acts from the vertical direction (see FIG. 7).
It does not change much compared to

The collapse characteristic can be easily adjusted. Therefore, it is easy to set a good energy absorption characteristic with respect to the load from each direction.
