Claims (4)

バンパ部材と、車両骨格部材との間に、車両衝突時の衝撃を軸方向の圧縮荷重として受ける衝撃吸収部材を備えた車両の衝撃吸収構造であって、
前記衝撃吸収部材は、柱状の木材であり、その繊維方向が軸方向と平行であり、
前記衝撃吸収部材の一方の端面は、前記バンパ部材又は前記車両骨格部材の一方にその一部分のみが面接触を介して連接されており、
前記衝撃吸収部材の他方の端面は、前記バンパ部材又は前記車両骨格部材の他方にその全体を面接触を介して支持可能に連接されており、
前記衝撃吸収部材は、衝突開始時は、前記一方の端面が一部分のみで圧縮荷重を受けて局所的に圧縮変形し、該局所的な圧縮変形を経て最終的には前記一方の端面が全体で圧縮荷重を受けることを特徴とする車両の衝撃吸収構造。 A shock absorbing structure for a vehicle including an impact absorbing member that receives an impact at the time of a vehicle collision as a compressive load in an axial direction between a bumper member and a vehicle skeleton member,
The shock absorbing member is a columnar wood, the fiber direction is parallel to the axial direction,
One end surface of the shock absorbing member is connected to one of the bumper member or the vehicle skeleton member only through a surface contact ,
The other end face of the shock absorbing member is connected to the other of the bumper member or the vehicle skeleton member so as to be able to support the whole through surface contact ,

The one end face of the shock absorbing member is connected to one of the bumper member, the bumper member, or the vehicle skeleton member via an interposition.
The intervening object has an impact transmission portion having rigidity higher than that of the impact absorbing member, and the impact transmitting portion is disposed so as to overlap with only a part of the one end surface of the impact absorbing member. Vehicle shock absorption structure. 請求項３に記載の車両の衝撃吸収構造であって、
前記衝撃吸収部材の前記一方の端面は、軸方向に直交する一平面のみで形成されていることを特徴とする車両の衝撃吸収構造。
The shock absorbing structure for a vehicle according to claim 3,
The shock absorbing structure for a vehicle, wherein the one end face of the shock absorbing member is formed of only one plane orthogonal to the axial direction.
