請求項２に記載する本発明の車体前部構造によれば、アッパメンバには当て部が設けられ、この当て部は、フードの閉止状態では荷重伝達部材の前端面と対向し、フードの閉止状態でかつアッパメンバに車両前方側から荷重が入力された状態では荷重伝達部材の前端面に当って荷重伝達部材に荷重を伝達する。このため、アッパメンバ側からの荷重は荷重伝達部材に安定的に伝達されることになり、荷重伝達部材に安定的に伝達された荷重がさらにピラー上部へ伝達される。   According to the vehicle body front portion structure of the present invention described in claim 2, the upper member is provided with a contact portion, and this contact portion faces the front end surface of the load transmitting member when the hood is closed, and the hood is closed. In addition, when a load is input to the upper member from the front side of the vehicle, the load hits the front end surface of the load transmitting member and transmits the load to the load transmitting member. For this reason, the load from the upper member side is stably transmitted to the load transmission member, and the load stably transmitted to the load transmission member is further transmitted to the upper part of the pillar.

以上説明したように、本発明に係る請求項１に記載の車体前部構造によれば、アッパメンバに車両前方側から荷重が入力された際にフロントピラー側へ効率的に荷重を伝達することができるという優れた効果を有する。   As described above, according to the vehicle body front part structure according to claim 1 of the present invention, when a load is input to the upper member from the vehicle front side, the load can be efficiently transmitted to the front pillar side. It has an excellent effect of being able to.

請求項２に記載の車体前部構造によれば、アッパメンバに車両前方側から荷重が入力された際にフロントピラー側へ一層効率的に荷重を伝達することができるという優れた効果を有する。   According to the vehicle body front part structure of the second aspect, there is an excellent effect that when the load is input to the upper member from the front side of the vehicle, the load can be transmitted more efficiently to the front pillar side.

Has been. The abutting portion 56A is a part of a convex portion 56 formed by projecting a part of the upper wall portion 30A of the upper member 30 to the upper side of the vehicle, and the load F is applied to the upper member 30 from the front side of the vehicle while the hood 14 is closed. In the state in which is inputted, the load is transmitted to the load transmitting member 40 by hitting the front end face 40F of the load transmitting member 40.

また、図１及び図３に示されるように、荷重伝達部材４０において、湾曲面４０Ｃの後端と上面後部２４０Ａの後端とは後端面４０Ｇによって繋がれている。後端面４０Ｇは、通常姿勢で車両上方へ向けて車両前方側に若干傾斜している。図１に示されるように、フード１４の閉止状態では、荷重伝達部材４０の後端面４０Ｇは、ピラー上部２８の受け部５８Ａに対向しており、後端面４０Ｇと受け部５８Ａとは互いに平行に配置されている。受け部５８Ａは、ピラー上部２８の前端側が車両前方側に突出して形成された凸部５８の一部とされ、フード１４の閉止状態でかつアッパメンバ３０に車両前方側から荷重Ｆが入力された状態では荷重伝達部材４０の後端面４０Ｇが当って荷重を受けるようになっている。   As shown in FIGS. 1 and 3, in the load transmission member 40, the rear end of the curved surface 40C and the rear end of the upper surface rear portion 240A are connected by a rear end surface 40G. The rear end surface 40G is slightly inclined toward the vehicle front side in the normal posture toward the vehicle upper side. As shown in FIG. 1, in the closed state of the hood 14, the rear end surface 40G of the load transmitting member 40 faces the receiving portion 58A of the pillar upper portion 28, and the rear end surface 40G and the receiving portion 58A are parallel to each other. Has been placed. The receiving portion 58A is a part of a convex portion 58 formed by projecting the front end side of the pillar upper portion 28 toward the front side of the vehicle, and the load F is input to the upper member 30 from the front side of the vehicle while the hood 14 is closed. Then, the rear end surface 40G of the load transmitting member 40 hits and receives a load.

すなわち、荷重伝達部材４０は、フード１４の閉止状態では、前端面４０Ｆ（前端）がアッパメンバ３０側に配置されると共に後端面４０Ｇ（後端）がピラー上部２８の前端の受け部５８Ａの車両前方側に配置され、フード１４の閉止状態でかつアッパメンバ３０に車両前方側から荷重Ｆが入力された状態では荷重Ｆの一部をピラー上部２８の前端の受け部５８Ａに伝達するようになっている（図５参照）。このように、本実施形態に係る車体前部構造は、荷重伝達部材４０によってアッパメンバ３０側からピラー上部２８側への荷重伝達経路が設定された構造になっている。   That is, when the hood 14 is in the closed state, the load transmitting member 40 has a front end surface 40F (front end) disposed on the upper member 30 side and a rear end surface 40G (rear end) on the front side of the receiving portion 58A of the front end of the pillar upper portion 28. In the state where the hood 14 is closed and the load F is input to the upper member 30 from the front side of the vehicle, a part of the load F is transmitted to the receiving portion 58A at the front end of the pillar upper portion 28. (See FIG. 5). As described above, the vehicle body front portion structure according to the present embodiment has a structure in which a load transmission path from the upper member 30 side to the pillar upper portion 28 side is set by the load transmission member 40.

（作用・効果）
次に、上記実施形態の作用及び効果について説明する。 (Action / Effect)
Next, the operation and effect of the above embodiment will be described.

図１に示されるように、本実施形態に係る車体前部構造では、フード１４の後端部１６の両サイドにおけるフード下方側の面１８に荷重伝達部材４０が取り付けられている。荷重伝達部材４０は、前述の通り、フード１４の閉止状態では、前端面４０Ｆがアッパメンバ３０側に配置されると共に後端面４０Ｇがピラー上部２８の前端の車両前方側に配置されている。   As shown in FIG. 1, in the vehicle body front structure according to the present embodiment, a load transmission member 40 is attached to the hood lower surface 18 on both sides of the rear end portion 16 of the hood 14. As described above, in the closed state of the hood 14, the load transmitting member 40 has the front end surface 40F disposed on the upper member 30 side and the rear end surface 40G disposed on the vehicle front side of the front end of the pillar upper portion 28.

ここで、アッパメンバ３０には当て部５６Ａが設けられ、この当て部５６Ａは、フード１４の閉止状態では荷重伝達部材４０の前端面４０Ｆと対向し、フード１４の閉止状態でかつアッパメンバ３０に車両前方側から荷重Ｆが入力された状態では、図５に示されるように、荷重伝達部材４０の前端面４０Ｆに当って荷重ｆ（荷重Ｆの一部）を伝達する。また、図１に示されるように、ピラー上部２８の前端側には受け部５８Ａが設けられ、この受け部５８Ａは、フード１４の閉止状態では荷重伝達部材４０の後端面４０Ｇと対向し、フード１４の閉止状態でかつアッパメンバ３０に車両前方側から荷重Ｆが入力された状態では、図５に示されるように、荷重伝達部材４０の後端面４０Ｇが当って荷重ｆ（荷重Ｆの一部）を受ける。   Here, the upper member 30 is provided with an abutting portion 56A. The abutting portion 56A faces the front end surface 40F of the load transmitting member 40 in the closed state of the hood 14, and is in a closed state of the hood 14 and on the upper member 30 in front of the vehicle. In a state where the load F is input from the side, the load f (a part of the load F) is transmitted by hitting the front end surface 40F of the load transmitting member 40 as shown in FIG. Further, as shown in FIG. 1, a receiving portion 58A is provided on the front end side of the pillar upper portion 28, and this receiving portion 58A faces the rear end face 40G of the load transmitting member 40 when the hood 14 is closed. 14, and when the load F is input to the upper member 30 from the front side of the vehicle, as shown in FIG. 5, the rear end face 40 </ b> G of the load transmitting member 40 hits and the load f (part of the load F) is applied. Receive.

このため、フード１４の閉止状態でかつアッパメンバ３０に車両前方側から前面衝突時の荷重Ｆが入力された際には、アッパメンバ３０の当て部５６Ａが荷重伝達部材４０の対向面となる前端面４０Ｆに当って（直接接触して）荷重ｆを荷重伝達部材４０に安定的に伝達し、さらに荷重伝達部材４０の後端面４０Ｇがピラー上部２８の対向面となる受け部５８Ａに当って（直接接触して）当該受け部５８Ａが荷重ｆを受け、ピラー上部２８に安定的に荷重ｆが伝達される。このように、アッパメンバ３０から荷重伝達部材４０を介してピラー上部２８の前端の受け部５８Ａに荷重ｆが伝達されることで、モーメントの発生が抑えられ、荷重ｆがスムーズに流れる。   For this reason, when the load F at the time of frontal collision is input to the upper member 30 from the front side of the vehicle in the closed state of the hood 14, the front end surface 40 </ b> F in which the contact portion 56 </ b> A of the upper member 30 becomes the opposing surface of the load transmission member 40. The load f is stably transmitted to the load transmitting member 40 (in direct contact), and the rear end surface 40G of the load transmitting member 40 is in contact with the receiving portion 58A that is the opposing surface of the pillar upper portion 28 (direct contact). The receiving portion 58A receives the load f, and the load f is stably transmitted to the pillar upper portion 28. In this way, the load f is transmitted from the upper member 30 to the receiving portion 58A at the front end of the pillar upper portion 28 via the load transmitting member 40, so that the generation of moment is suppressed and the load f flows smoothly.

ここで、対比構造と比較しながら補足説明すると、例えば、フード側のヒンジ構成部とアッパメンバ側（ボデー側）のヒンジ構成部とを引っ掛けることによって前面衝突時のフードの後退を抑えるような対比構造では、ヒンジ構成部はピラー上部へ荷重伝達する役割を果たしていない。すなわち、このような対比構造では、アッパメンバ側からフード側を経てピラー上部側へ荷重を伝達する入力経路が存在しない。このため、アッパメンバ側からピラー下部への荷重伝達位置とピラー上部の前端側の図心とが車両上下方向にオフセットすることになるので、アッパメンバ側からのフロントピラー側への荷重入力時にはモーメント（車両の左側面視で反時計回りのモーメント）が発生してしまい、フロントピラー側へ効率的に荷重を伝達することができない。これに対して、本実施形態に係る車体前部構造では、アッパメンバ３０から荷重伝達部材４０を介してピラー上部２８へ直接荷重を伝達しており、ピラー上部２８への荷重伝達位置とピラー上部２８の前端側（下端側）の図心Ｘとの車両上下方向にオフセット量がほとんどなく、モーメントの発生を大幅に低減することができる。また、本実施形態に係る車体前部構造では、ピラー上部２８への荷重入力方向（矢印ｆ参照）もピラー上部２８の図心線ＣＬにほぼ沿っているので、荷重を効率的に伝達することが可能になる。   Here, a supplementary explanation will be made while comparing with the comparison structure. For example, the comparison structure that suppresses the hood from retreating at the time of a frontal collision by hooking the hinge structure part on the hood side and the hinge structure part on the upper member side (body side). Then, the hinge component does not play a role of transmitting a load to the upper part of the pillar. That is, in such a contrast structure, there is no input path for transmitting a load from the upper member side to the pillar upper side through the hood side. For this reason, the load transmission position from the upper member side to the pillar lower part and the centroid on the front end side of the pillar upper part are offset in the vertical direction of the vehicle. Therefore, when the load is input from the upper member side to the front pillar side, the moment (vehicle (A counterclockwise moment in the left side view) is generated, and the load cannot be efficiently transmitted to the front pillar side. On the other hand, in the vehicle body front structure according to the present embodiment, the load is directly transmitted from the upper member 30 to the pillar upper portion 28 via the load transmitting member 40, and the load transmission position to the pillar upper portion 28 and the pillar upper portion 28 are transmitted. There is almost no offset amount in the vehicle vertical direction with respect to the centroid X on the front end side (lower end side), and the generation of moments can be greatly reduced. Further, in the vehicle body front structure according to the present embodiment, the load input direction (see arrow f) to the pillar upper portion 28 is also substantially along the centroid line CL of the pillar upper portion 28, so that the load can be transmitted efficiently. Is possible.

以上説明したように、本実施形態に係る車体前部構造によれば、アッパメンバ３０に車両前方側から荷重Ｆが入力された際にフロントピラー２４側へ効率的に荷重を伝達することができる。   As described above, according to the vehicle body front structure according to the present embodiment, when the load F is input to the upper member 30 from the front side of the vehicle, the load can be efficiently transmitted to the front pillar 24 side.

A load f1 (a part of the load F) is transmitted to.

また、アッパメンバ３０の上壁部３０Ａ側には、第一凹部６４の車両後方側に第二凹部６６が形成されている。第二凹部６６は、車両上方側に開口し、フード１４の閉止状態では荷重伝達部材４０の第二凸部６２が入り込む位置に設定されかつ第二凸部６２の前側端面６２Ａと対向する第二当部６６Ａを備えている。第二当部６６Ａと前側端面６２Ａとはフード１４の閉止状態では互いに平行に配置されるように設定されている。第二当部６６Ａは、フード１４の閉止状態でかつアッパメンバ３０に車両前方側から荷重Ｆが入力された状態では荷重伝達部材４０の第二凸部６２の前側端面６２Ａに当って荷重伝達部材４０荷重ｆ２（荷重Ｆの一部）を伝達するようになっている。   A second recess 66 is formed on the upper wall 30 </ b> A side of the upper member 30 on the vehicle rear side of the first recess 64.
