ところで、特許文献１には、カウルグリルの前側縦壁部に、車両上方からの衝撃荷重入力時に対する変形促進用として車幅方向に水平方向に延び後方に向けて屈曲した屈曲部が形成された構成が開示されている。 However, it is difficult to form a bent portion of the front end portion of the cowl grill in the vehicle width direction due to the relationship with the side surface portion extending rearward, and it is generally in the vertical direction in the side view. In many cases, it is formed in a straight shape that extends to the front, so there is a concern that the initial load at the time of load input will increase at the side end of the front surface of the cowl grill, and there is room for improvement from the viewpoint of reducing the initial load. It was.
By the way, in Patent Document 1, a bent portion extending horizontally in the vehicle width direction and bent rearward is formed on the front vertical wall portion of the cowl grill to promote deformation when an impact load is input from above the vehicle. The configuration is disclosed.

しかしながら、該特許文献１に開示された従来構造においては、上記屈曲部の屈曲形状に沿って、第１斜面リブ、第２斜面リブ、立設リブ、垂下リブを形成したものであるから、これらリブにより屈曲部の剛性が高くなり、荷重入力時に充分な初期荷重の低減を図ることができない、という問題点があった。 However, in the conventional structure disclosed in Patent Document 1, the first slope rib, the second slope rib, the standing rib, and the hanging rib are formed along the bent shape of the bent portion. There is a problem that the rigidity of the bent portion is increased by the rib, and the initial load cannot be sufficiently reduced when the load is input.

(See FIG. 9), and a notch 28 is formed at a side end portion extending or adjacent to the above-mentioned upper bent portion b1 (see FIGS. 3 to 6).

これにより、上方からの荷重入力時における前面部２４の車幅方向側端部の屈曲方向への変形について、上記切欠き部２８を起点（いわゆる折れ切っ掛け）として変形させ、車幅方向に延びる上部屈曲部ｂ１と相俟って、上方からの荷重入力時には、カウルグリル２２の車幅方向の全領域で初期荷重の低減を図るよう構成したものである。 As a result, regarding the deformation of the front end portion 24 in the vehicle width direction side end portion in the bending direction when a load is input from above, the notch portion 28 is deformed as a starting point (so-called breakage), and the upper portion extending in the vehicle width direction is deformed. In combination with the bent portion b1, when a load is input from above, the initial load is reduced in the entire region of the cowl grill 22 in the vehicle width direction.

図７、図８で示したように、カウルグリル２２の前面部２４上面における上述の取付け座２４ａには、ボンネットの後端部との間をシールするウエザストリップ３０が配置されており、図１、図２、図３、図９に示すように、このウエザストリップ３０の車幅方向左右両側端は、カウルグリル２２より車幅方向側方まで延びると共に、この車幅方向側方の下方には、カウルグリル２２の前面部２４に隣接し、かつ当接する型成形部３１が一体形成されており、この型成形部３１で、図９に示すように、上述の切欠き部２８の前方、詳しくは、前側の面を覆っている。
具体的には、図９に示すように、上述の型成形部３１で、上述の切欠き部２８を含んで前面部２４のストレート部２４ｇ、連結壁２４ｄの前側の面を覆っている。 As shown in FIGS. 7 and 8, a weather strip 30 for sealing between the cowl grill 22 and the rear end portion of the bonnet is arranged on the mounting seat 24a on the upper surface of the front portion 24 of the cowl grill 22. As shown in 1, FIG. 2, FIG. 3, and FIG. 9, both left and right ends of the weather strip 30 in the vehicle width direction extend from the cowl grill 22 to the side in the vehicle width direction and downward in the vehicle width direction.

この実施例では、上述の切欠き部２８を型成形部３１で覆っており、これにより、エンジンの熱気のみならず臭気の上記閉断面部内への侵入を抑制すると共に、車両前方側からの見栄え向上を図るよう構成したものである。 An engine is mounted below the bonnet, and heat is generated from the engine as well as odor. An outside air intake for an air conditioner is generally provided in the closed cross section below the upper surface 23 of the cowl grill 22 shown in FIG. 7, and when the hot air of the engine enters the closed cross section of the cowl grill 22, air conditioning is performed. Performance will be affected.
In this embodiment, the notch 28 is covered with the molding portion 31, which suppresses not only the hot air of the engine but also the odor from entering the closed cross-section and looks good from the front side of the vehicle. It is configured to improve.

図７、図８に示すように、上述の上部屈曲部ｂ１の背面から後方、詳しくは、後上方向に延びるフランジ部２９が一体形成されている。図６に背面図で示すように、上記フランジ部２９は、切欠き部２８の近傍まで車幅方向に延びている。また、カウルグリル２２の上面部２３と前面部２４は分割形成されている。換言すれば、カウルグリル２２の上面部２３と前面部２４とは、それぞれ別部材にて形成されている。 As shown in FIGS. 7 and 8, a flange portion 29 extending rearward from the back surface of the above-mentioned upper bent portion b1, specifically, a flange portion 29 extending in the rear-upward direction is integrally formed. As shown in the rear view of FIG. 6, the flange portion 29 extends in the vehicle width direction to the vicinity of the notch portion 28. Further, the upper surface portion 23 and the front surface portion 24 of the cowl grill 22 are separately formed. In other words, the upper surface portion 23 and the front surface portion 24 of the cowl grill 22 are formed of separate members.

そして、図８に示すように、上述のフランジ部２９には、係合孔２９ａが開口形成される一方で、上述の上面部２３には、係合突起２３ａを備えた取付け片２３ｂが下方に延びるように一体形成されており、上面部２３の取付け片２３ｂ下端部をフランジ部２９の係合孔２９ａに貫通し、取付け片２３ｂの係合突起２３ａを係合孔２９ａの孔縁に係合させることで、上面部２３を、前面部２４において上部屈曲部ｂ１から後方に延びるフランジ部２９に取付けるよう構成している。 Then, as shown in FIG. 8, the engagement hole 29a is formed in the flange portion 29, while the mounting piece 23b provided with the engagement protrusion 23a is downwardly formed in the upper surface portion 23. It is integrally formed so as to extend, the lower end of the mounting piece 23b of the upper surface portion 23 penetrates through the engaging hole 29a of the flange portion 29, and the engaging projection 23a of the mounting piece 23b engages with the hole edge of the engaging hole 29a. The upper surface portion 23 is configured to be attached to the flange portion 29 extending rearward from the upper bent portion b1 on the front surface portion 24.

図７、図８に示すように、上述の上部屈曲部ｂ１におけるフランジ部２９の基端側の上下には、当該上部屈曲部ｂ１の肉厚を薄くする上部凹溝２４ｈ、下部凹溝２４ｉがそれぞれ形成されている。
上部凹溝２４ｈは、図８に示すように、第１スラント部２４ｂの下端部背面をテーパ状に切り落とす形状に形成されており、下部凹溝２４ｉは、同図に示すように逆向きのＶ字状に形成されている。 As shown in FIGS. 7 and 8, upper concave grooves 24h and lower concave grooves 24i for reducing the wall thickness of the upper bent portion b1 are above and below the base end side of the flange portion 29 in the above-mentioned upper bent portion b1. Each is formed.
As shown in FIG. 8, the upper concave groove 24h is formed in a shape in which the back surface of the lower end portion of the first slant portion 24b is cut off in a tapered shape, and the lower concave groove 24i is V in the opposite direction as shown in the figure. It is formed in a character shape.

そして、上部凹溝２４ｈは切欠き部２８まで車幅方向に連続して形成されており、当該切欠き部２８が図９に示すように上部凹溝２４ｈと連続している。また、下部凹溝２４ｉはフランジ部２９の車幅方向の全幅にわたって連続して形成されている。

なお、図６、図７、図８において、２４ｊはロアノッチ部ｎ２と対応する前面部２４の背面側において、車幅方向に間欠的に設けられたフック部である。 The upper concave groove 24h is continuously formed up to the notch 28 in the vehicle width direction, and the notch 28 is continuous with the upper concave groove 24h as shown in FIG. Further, the lower concave groove 24i is continuously formed over the entire width of the flange portion 29 in the vehicle width direction.
By providing the upper concave groove 24h continuous to the notch 28 in the vehicle width direction, the bending deformation of the notch 28 is assisted by the upper concave groove 24h, and the reduction of the initial load is further improved. It is configured.
In FIGS. 6, 7, and 8, 24j is a hook portion intermittently provided in the vehicle width direction on the back side of the front surface portion 24 corresponding to the lower notch portion n2.

図１０の（ａ）は、前面部２４の車幅方向側部のみを部分的に示す背面図、図１０の（ｂ）〜（ｅ）は図１０のＤ−Ｄ線に沿う射出成形金型の要部の型割り構造を示し、図１０の（ｂ）は比較例１の構造を示す断面図、図１０の（ｃ）は比較例２の構造を示す断面図、図１０の（ｄ）は比較例３の構造を示す断面図、図１０の（ｅ）は本実施例の構造を示す断面図である。なお、説明の便宜上、図１０の（ｂ）〜（ｅ）において、射出成形後の前面部２４における各部の符号を付している。 FIG. 10 (a) is a rear view partially showing only the side portion of the front portion 24 in the vehicle width direction, and FIGS. 10 (b) to 10 (e) are injection molding dies along the DD line of FIG. 10 (b) is a cross-sectional view showing the structure of Comparative Example 1, FIG. 10 (c) is a cross-sectional view showing the structure of Comparative Example 2, and FIG. 10 (d) shows the mold division structure of the main part of the above. Is a cross-sectional view showing the structure of Comparative Example 3, and FIG. 10 (e) is a cross-sectional view showing the structure of the present embodiment. For convenience of explanation, reference numerals are given to the front portions 24 after injection molding in FIGS. 10 (b) to 10 (e).

図１０の（ｂ）に示す比較例１の構造は、コア型ＣＯ１（いわゆる雄型）と、キャビティ型ＣＡ１（いわゆる雌型）と、スライド型ＳＬ１と、を備え、前面部２４の車幅方向側部を直線形状（ストレート部２４ｇ参照）に成形するもので、スライド型ＳＬ１には上部凹溝２４ｈを成形する形状面が形成されているものの、コア型ＣＯ１には切欠き部２８を成形する型部は形成されていない。 The structure of Comparative Example 1 shown in FIG. 10B includes a core type CO1 (so-called male type), a cavity type CA1 (so-called female type), and a slide type SL1, and the front portion 24 is provided in the vehicle width direction. The side portion is formed into a straight shape (see the straight portion 24 g), and the slide type SL1 is formed with a shape surface for forming the upper concave groove 24h, but the core type CO1 is formed with a notch portion 28. The mold is not formed.

このため、成形された前面部２４の車幅方向側部には切欠き部２８が形成されないので、当該前面部２４の車幅方向側部の上下方向の剛性が高く、上方からの荷重入力時に該車幅方向側部は折れなかった。なお、図１０の（ｂ）における図中の矢印は型の移動方向を示し、この型の移動方向は図１０の（ｃ）〜（ｅ）についても同様であるので、図１０の（ｃ）〜（ｅ）においては当該矢印の図示を省略している。 Therefore, since the notch 28 is not formed on the vehicle width direction side portion of the molded front surface portion 24, the vertical rigidity of the vehicle width direction side portion of the front surface portion 24 is high, and when a load is input from above. The side portion in the vehicle width direction did not break. The arrow in the figure in FIG. 10B indicates the moving direction of the mold, and the moving direction of this mold is the same for (c) to (e) in FIG. 10, so (c) in FIG. In (e), the illustration of the arrow is omitted.

図１０の（ｃ）に示す比較例２の構造は、コア型ＣＯ２と、キャビティ型ＣＡ２と、スライド型ＳＬ２と、を備え、前面部２４の車幅方向側部を直線形状に成形するもので、スライド型ＳＬ２には上部凹溝２４ｈを成形する形状面が形成されており、コア型ＣＯ２には、スライド型ＳＬ２と当接して切欠き部２８を成形する型部としての突起４２が形成されている。 The structure of Comparative Example 2 shown in FIG. 10 (c) includes a core type CO2, a cavity type CA2, and a slide type SL2, and forms the side portion of the front portion 24 in the vehicle width direction into a linear shape. , The slide type SL2 is formed with a shape surface for forming the upper concave groove 24h, and the core type CO2 is formed with a protrusion 42 as a mold part for forming the notch 28 in contact with the slide type SL2. ing.

この比較例２の場合、スライド型ＳＬ２下面と突起４２下面とをキャビティ部（成形用の空間部）にて一直線上に型合わせしている。この場合、コア型ＣＯ２とスライド型ＳＬ２の２つの型の角部の合わせが生じ、バリ（フラッシュと同意）が発生する可能性が高く好ましくなかった。 In the case of Comparative Example 2, the lower surface of the slide type SL2 and the lower surface of the protrusion 42 are aligned with each other at the cavity portion (space portion for molding). In this case, the corners of the two types, the core type CO2 and the slide type SL2, are aligned, which is not preferable because there is a high possibility that burrs (same as flush) will occur.

図１０の（ｄ）に示す比較例３の構造は、コア型ＣＯ３と、キャビティ型ＣＡ３と、スライド型ＳＬ３と、を備え、前面部２４の車幅方向側部を直線形状に成形するもので、コア型ＣＯ３には、スライド型ＳＬ３と当接して切欠き部２８を成形する型部としての突起４３が形成されている。
この比較例３の場合、キャビティ型ＣＡ３とスライド型ＳＬ３とコア型ＣＯ３との３つの型の角部の合わせが生じ、バリが発生する可能性が著しく高く好ましくなかった。 The structure of Comparative Example 3 shown in FIG. 10D is provided with a core type CO3, a cavity type CA3, and a slide type SL3, and the side portion of the front portion 24 in the vehicle width direction is formed into a linear shape. The core type CO3 is formed with a protrusion 43 as a mold part that comes into contact with the slide type SL3 to form the notch 28.
In the case of Comparative Example 3, the corners of the three types of the cavity type CA3, the slide type SL3, and the core type CO3 were aligned, and burrs were extremely likely to occur, which was not preferable.

つまり、図１０の（ｃ），（ｄ）で示す比較例２，３の場合には、突起４２，４３の形成により、射出成形後の前面部２４には、切欠き部２８が設けられ、上方からの荷重入力時における初期荷重の低減を図ることができる一方で、角部の合わせに起因してバリが発生する可能性が高く、好ましいものではなかった。 That is, in the case of Comparative Examples 2 and 3 shown in FIGS. 10 (c) and 10 (d), the cutout portion 28 is provided on the front surface portion 24 after injection molding due to the formation of the protrusions 42 and 43. While it is possible to reduce the initial load when the load is input from above, there is a high possibility that burrs will occur due to the alignment of the corners, which is not preferable.

図１０の（ｅ）に示す本実施例の構造は、コア型ＣＯと、キャビティ型ＣＡと、スライド型ＳＬと、を備え、前面部２４の車幅方向側部を直線形状に成形するもので、スライド型ＳＬには上部凹溝２４ｈを成形する形状面が形成されており、コア型ＣＯには、スライド型ＳＬと当接して切欠き部２８を成形する型部としての突起４０が形成されている。 The structure of this embodiment shown in FIG. 10 (e) includes a core type CO, a cavity type CA, and a slide type SL, and forms the side portion of the front portion 24 in the vehicle width direction into a linear shape. , The slide type SL is formed with a shape surface for forming the upper concave groove 24h, and the core type CO is formed with a protrusion 40 as a mold part for forming the notch 28 in contact with the slide type SL. ing.

図１０の（ｅ）に示す本実施例の場合、突起４０の下部先端の角部はスライド型ＳＬの下端の角部に対して上方へ段差を有しており、コア型ＣＯの上記角部（突起４０の下端の角部）はスライド型ＳＬの合わせ面に当接しており、キャビティ型ＣＡの上端角部もスライド型ＳＬの合わせ面に当接しており、比較例２，３のような角部同士の当接が回避されるので、バリの発生を抑制することができた。
しかも、上述の切欠き部２８および上部凹溝２４ｈの形成により、上方からの荷重入力時に、これら両者２８，２４ｈにより初期荷重の低減を図ることができる。 In the case of this embodiment shown in FIG. 10 (e), the corner portion of the lower tip of the protrusion 40 has a step upward with respect to the corner portion of the lower end of the slide type SL, and the corner portion of the core type CO. (The corner of the lower end of the protrusion 40) is in contact with the mating surface of the slide type SL, and the upper end corner of the cavity type CA is also in contact with the mating surface of the slide type SL, as in Comparative Examples 2 and 3. Since the contact between the corners is avoided, the occurrence of burrs can be suppressed.
Moreover, by forming the notch 28 and the upper concave groove 24h described above, it is possible to reduce the initial load by both 28 and 24h when the load is input from above.
