Description

本発明は、車両に備えられるラジエータグリルとそれを備えた車両に関する。 The present invention relates to a radiator grill provided in a vehicle and a vehicle including the same.

冷却システムを必要とする内燃機関などの装置を搭載した車両においては、ラジエータが多く用いられ、このラジエータの前方には、ラジエータグリルが配置されている。通常、このラジエータグリルは合成樹脂で射出成形されることが多い。このラジエータグリルには、裏表面に連通するネジ挿通穴を有しているシール部材が取付けネジによって取り付けられ、設置されている。 In a vehicle equipped with a device such as an internal combustion engine that requires a cooling system, a radiator is often used, and a radiator grill is disposed in front of the radiator. Usually, this radiator grill is often injection-molded with a synthetic resin. A seal member having a screw insertion hole communicating with the back surface is attached to the radiator grille by a mounting screw.

このラジエータグリルにシール部材を取り付ける構造に関しては、ラバー部材（シール部材）を、ラジエータグリル側に一体的に形成され、ラジエータグリルの裏面から突出した中空丸棒状のものからなり、その内部にビス止め用の凹孔が形成されたボスにビスを用いて固定する固定構造が知られている（例えば、特許文献１参照）。 With regard to the structure for attaching the seal member to the radiator grill, the rubber member (seal member) is integrally formed on the radiator grill side, and is formed of a hollow round bar shape protruding from the back surface of the radiator grill. There is known a fixing structure that uses a screw to fix to a boss formed with a concave hole (for example, see Patent Document 1).

しかしながら、このラジエータグリルにボスを設けて取付ネジを挿入する構成で、ラジエータグリルを合成樹脂で射出成形すると、このボスの側壁部のあるラジエータグリルの表面側に、成形収縮によって生じるへこみや窪みであるヒケが発生し、見栄えが悪くなるという問題がある。一方、このヒケの発生を防止しようとして側壁部の厚みを薄くすると、ボスの強度が低下してしまうという問題が生じる。このラジエータグリルの表面は、車両の前方に配置されるので、このヒケの問題は車両の意匠の面から好ましくなく、改善が望まれる課題となっている。 However, when the radiator grille is injection molded with synthetic resin with a boss provided on the radiator grille and a mounting screw is inserted, the surface of the radiator grille having the side wall portion of the boss has dents and depressions caused by molding shrinkage. There is a problem that a certain sink occurs and it looks bad. On the other hand, if the thickness of the side wall is reduced in order to prevent the occurrence of sink marks, there arises a problem that the strength of the boss is lowered. Since the surface of the radiator grille is disposed in front of the vehicle, the problem of sink marks is not preferable from the viewpoint of the design of the vehicle, and is a problem that is desired to be improved.

特開２０００−２６５２７９号公報JP 2000-265279 A

本発明は、上記のことを鑑みてなされたものであり、その目的は、車両に備えられるラジエータグリルにおいて、ラジエータグリルに組み付け部材を取付ける際に、ネジ等の固定部材が螺合され、ラジエータグリルの裏面に配置されたボスの部分において、強度が確保できると共に、射出成形の際にラジエータグリルの表面にヒケができないようにすることができるラジエータグリルと車両を提供することである。 The present invention has been made in view of the above, and an object of the present invention is to provide a radiator grille provided in a vehicle in which a fixing member such as a screw is screwed when the assembly member is attached to the radiator grille. It is an object to provide a radiator grill and a vehicle that can ensure strength at the boss portion disposed on the back surface of the radiator grille and prevent the surface of the radiator grille from sinking during injection molding.

上記の目的を達成するための本発明のラジエータグリルは、車両に備えられるラジエータグリルにおいて、前記ラジエータグリルの裏面に設けられ、表面から裏面に向けた第１方向に延出する延出部と、前記延出部の先端部に備えられ、前記ラジエータグリルの裏面に配置する組み付け部材を組み付け可能なボス部と、を備え、前記延出部は、前記ラジエータグリルの裏面との接合面の面積を、前記ボス部の前記先端部との接合面の面積よりも小さくして構成されると共に、前記先端部から前記ラジエータグリルの裏面に延びる側壁部を有すると共に、前記側壁部と前記先端部と前記ラジエータグリルの裏面とで囲まれた空隙を有して構成され、前記側壁部は、前記第１方向に対し垂直な面での断面形状が、前記空隙の開口側に対向する奥側の部分が前記ボス部の中心を中心とする円弧形状をしているＵ字状に形成され、前記ボス部は、前記ボス部の円筒部分と前記先端部に接続し、前記先端部に接続する部分が前記ボス部の円筒部分から前記側壁部の前記奥側の部分に向けて延びている補強リブを有して構成されている。 The radiator grill of the present invention for achieving the above object is a radiator grill provided in a vehicle, provided on the back surface of the radiator grill, and extending in a first direction from the front surface toward the back surface, A boss part provided at a tip part of the extension part and capable of assembling an assembly member disposed on the back surface of the radiator grille, and the extension part has an area of a joint surface with the back surface of the radiator grille. The boss portion is configured to be smaller than the area of the joint surface with the tip portion, and has a side wall portion extending from the tip portion to the back surface of the radiator grill, and the side wall portion, the tip portion, and the is configured with a void surrounded by the rear surface of the radiator grille, the side wall section, rear side the relative first direction in which the cross-sectional shape at a plane perpendicular, facing the open side of the gap The portion is formed in a U shape having an arc shape centered on the center of the boss portion, and the boss portion is connected to the cylindrical portion of the boss portion and the tip portion, and is connected to the tip portion. Has a reinforcing rib extending from the cylindrical portion of the boss portion toward the back side portion of the side wall portion .

この構成によれば、ラジエータグリルを車両に組み付けた際に、ボス部と延出部の先端部との接合面の面積よりも延出部とラジエータグリルの裏面との接合面の面積の方を小さく設定するので、延出部の先端部に対するボス部の厚みが確保でき、強度を十分に確保できると共に、ラジエータグリルに対する延出部の厚みを薄くすることができ、ラジエータグリルの表面にヒケができないようにすることができる。 According to this configuration, when the radiator grille is assembled to the vehicle, the area of the joint surface between the extension part and the back surface of the radiator grille is larger than the area of the joint surface between the boss part and the tip part of the extension part. Since it is set small, the thickness of the boss portion relative to the tip of the extension portion can be secured, the strength can be sufficiently secured, and the thickness of the extension portion relative to the radiator grill can be reduced, and sink marks are formed on the surface of the radiator grill. You can make it impossible.

また、延出部の強度を確保しながらも、空隙部分に対応する射出成形時にＵ字形状の中子をＵ字形状の側壁部の開口側に引出すことで、容易に成形できる。
また、上記のラジエータグリルにおいて、前記ボス部は、前記先端部との接合面の面積を、前記先端部との接合部に対し反対側の端部における前記第１方向に垂直な面の断面積よりも大きく構成されるよう、前記接合部と前記端部との間で前記第１方向に段部を外周部に有するように構成される。 In addition, while securing the strength of the extending portion, it can be easily molded by pulling out the U-shaped core to the opening side of the U-shaped side wall during injection molding corresponding to the gap portion.
Further, in the radiator grill, the boss portion has a cross-sectional area of a surface perpendicular to the first direction at an end portion on the opposite side to the joint portion with the tip portion. It is comprised so that it may have a step part in an outer peripheral part in the said 1st direction between the said junction part and the said edge part so that it may be comprised larger than this.

また、上記のラジエータグリルにおいて、前記組み付け部材は、挿入穴を有する板状のシール部材によって形成され、前記ボス部の先端に組み付けられた固定部材を介して前記ラジエータグリルに固定される。上記のボス部は強度が十分であるのでこの比較的簡単な固定方法により、ネジなどの固定部材でシール部材をラジエータグリルに強固に組み付けることができる。 In the radiator grill, the assembly member is formed by a plate-like seal member having an insertion hole, and is fixed to the radiator grill through a fixing member assembled to the tip of the boss portion. Since the boss portion has sufficient strength, the seal member can be firmly assembled to the radiator grille with a fixing member such as a screw by this relatively simple fixing method.

そして、上記の目的を達成するための本発明の車両は、車両の前部に備えられたエンジンルームの前方で、前記車両に組み付けられる、上記のラジエータグリルと、前記ラジエータグリルの後方で且つ前記エンジンルーム内に配置されたラジエータと、前記ラジエータの前方に配置され、前記ラジエータグリルの裏面に備えられた前記ボス部に組み付けられる前記組み付け部材と、を備えて構成される。 In order to achieve the above object, a vehicle according to the present invention includes a radiator grille to be assembled to the vehicle in front of an engine room provided at a front portion of the vehicle, the rear of the radiator grille, and the A radiator disposed in an engine room, and the assembly member disposed in front of the radiator and assembled to the boss portion provided on the back surface of the radiator grill.

本発明のラジエータグリルと車両によれば、車両に備えらえるラジエータグリルにおいて、ラジエータグリルを車両に組み付けた際に、ネジ等の固定部材が螺合され、ラジエータグリルの裏面に配置されたボス部において、ボス部と延出部の先端部との接合面の面積よりも、延出部とラジエータグリルの裏面との接合面の面積の方を小さく設定するので、ボス部の強度が確保できると共に、ラジエータグリルの表面にヒケができないようにすることができる。 According to the radiator grill and the vehicle of the present invention, in the radiator grille provided in the vehicle, when the radiator grille is assembled to the vehicle, a fixing member such as a screw is screwed and the boss part disposed on the back surface of the radiator grille Therefore, the area of the joint surface between the extension part and the back surface of the radiator grill is set smaller than the area of the joint surface between the boss part and the tip part of the extension part, so that the strength of the boss part can be secured. It is possible to prevent sink marks on the surface of the radiator grille.

図１及び図２に示すように、本発明に係る実施の形態のラジエータグリル２０は、車両に搭載されたラジエータに走行風を導く開口部２１を有し、このラジエータグリル２０に固定されて開口部２１を覆う二つの別体グリル３０を備えると共に、一つの組み付け部材４０を備えて構成される。この組み付け部材４０は、挿入穴４１を有する板状のシール部材である。そして、このラジエータグリル２０は、例えば、車両の前部に備えられたエンジンルーム内に配置されたラジエータの前方に配置される。 As shown in FIGS. 1 and 2, a radiator grill 20 according to an embodiment of the present invention has an opening 21 that guides running wind to a radiator mounted on a vehicle, and is fixed to the radiator grill 20 to be opened. The two separate grills 30 that cover the portion 21 are provided, and one assembly member 40 is provided. The assembly member 40 is a plate-like seal member having an insertion hole 41 . And this radiator grille 20 is arrange | positioned ahead of the radiator arrange | positioned, for example in the engine room with which the front part of the vehicle was equipped.

なお、以下の説明では、ラジエータグリル２０に関する方向として、ラジエータグリル２０の奥行方向を、表裏方向（表から裏をＸ方向）と言い、ラジエータグリル２０の長手方向を、水平方向（Ｘ方向から見て右側から左側をＹ方向）と言い、ラジエータグリル２０の高さ方向を、上下方向（下から上をＺ方向）と言うことにする。 In the following description, as the direction with respect to the radiator grille 20, the depth direction of the radiator grille 20 is referred to as the front / back direction (front to back is the X direction), and the longitudinal direction of the radiator grille 20 is the horizontal direction (viewed from the X direction). The left side from the right side is referred to as the Y direction), and the height direction of the radiator grille 20 is referred to as the vertical direction (from the bottom to the top in the Z direction).

この実施の形態のラジエータグリル２０では、別体グリル３０は、見栄えを考慮してラジエータグリル２０と別の色に形成される。この別体グリル３０はラジエータグリル２０の左右側端部の二か所に備えられるが、組み付け部材４０は、ラジエータグリル２０の右側端部のみの一か所でラジエータグリル２０を裏側から覆うように設けられる。 In the radiator grill 20 of this embodiment, the separate grill 30 is formed in a different color from the radiator grill 20 in consideration of appearance. The separate grill 30 is provided at two positions on the left and right end portions of the radiator grill 20, but the assembly member 40 covers the radiator grill 20 from the back side only at one position on the right end portion of the radiator grill 20. Provided.

本発明では、図３〜図５に示すように、組み付け部材４０をラジエータグリル２０に組み付けるため、ラジエータグリル２０の裏面に設けられた延出部２６と、この延出部２６の先端部２６ｂに備えられたボス部２７との二段構造の取付部が設けられる。このボス部２７は、ラジエータグリル２０の裏面に配置する組み付け部材４０を組み付けることができるようにボス孔２７ａを備えて形成する。従って、ボス部２７が延出部２６の先端部２６ｂに載置されたような形状となる。 In the present invention, as shown in FIGS. 3 to 5, in order to assemble the assembly member 40 to the radiator grille 20, the extension portion 26 provided on the back surface of the radiator grille 20 and the distal end portion 26 b of the extension portion 26 are provided. A mounting portion having a two-stage structure with the boss portion 27 provided is provided. The boss portion 27 is formed with a boss hole 27a so that the assembly member 40 disposed on the back surface of the radiator grill 20 can be assembled. Accordingly, the boss portion 27 is shaped to be placed on the distal end portion 26 b of the extending portion 26.

そして、延出部２６は、ラジエータグリル２０の裏面に表面から裏面に向けた第１方向（Ｘ方向）に延出して設けられる。また、延出部２６は、先端部２６ｂからラジエータグリル２０の裏面に延びる側壁部２６ａを有している。 The extending portion 26 is provided on the back surface of the radiator grille 20 so as to extend in the first direction (X direction) from the front surface to the back surface. Further, the extending part 26 has a side wall part 26 a extending from the front end part 26 b to the back surface of the radiator grill 20.

この延出部２６の側壁部２６ａは、ボス孔２７ａの挿通方向（−Ｘ方向）から見て、図３に示すように、Ｕ字状に形成され、この延出部２６は、側壁部２６ａと先端部２６ｂとラジエータグリル２０の裏面とで囲まれた空隙（中空部）２６ｃを有して構成される。また、ボス部２７は中央にボス孔２７ａを有する円筒形状に形成され、この円筒部分を補強する補強リブ２７ｂを備えている。 The side wall portion 26a of the extension portion 26 is formed in a U shape as shown in FIG. 3 when viewed from the insertion direction (−X direction) of the boss hole 27a. The extension portion 26 is formed of the side wall portion 26a. And a gap (hollow portion) 26c surrounded by the front end portion 26b and the back surface of the radiator grill 20. The boss portion 27 is formed in a cylindrical shape having a boss hole 27a at the center, and includes a reinforcing rib 27b that reinforces the cylindrical portion.

この側壁部２６ａは、ラジエータグリル２０の裏面と接合する第１部２６ａａと先端部２６ｂと接合する第２部２６ａｂとを有して形成される。この第１部２６ａａの第１方向（Ｘ方向）と垂直方向（Ｙ−Ｚ平面内の方向）の厚みｔａａは、延出部２６の先端部２６ｂと接合するボス部２７の接合部の厚みｔｂと比べて薄くなるように形成する。 The side wall portion 26a is formed to have a first portion 26aa that is joined to the back surface of the radiator grill 20 and a second portion 26ab that is joined to the tip portion 26b. The thickness taa of the first part 26aa in the first direction (X direction) and the vertical direction (direction in the YZ plane) is the thickness tb of the joint part of the boss part 27 joined to the tip part 26b of the extension part 26. It is formed to be thinner than

つまり、ボス部２７が延出部２６の先端部２６ｂと接合する部分の厚みｔｂはボス部２７が剛性を得ることができるように厚く形成される。これにより、ボス部２７の強度を確保する。一方、延出部２６の根元側の第１部２６ａａの厚みｔａａは、射出成形時にラジエータグリル２０の表面にヒケが出ない程度まで薄く形成する。これにより、ラジエータグリル２０の見栄えが悪くなるのを防止する。 That is, the thickness tb of the portion where the boss portion 27 is joined to the distal end portion 26b of the extending portion 26 is formed so as to be thick so that the boss portion 27 can obtain rigidity. Thereby, the strength of the boss portion 27 is ensured. On the other hand, the thickness taa of the first portion 26aa on the base side of the extending portion 26 is formed thin enough to prevent sink marks from appearing on the surface of the radiator grille 20 during injection molding. This prevents the appearance of the radiator grille 20 from deteriorating.

つまり、ラジエータグリル２０に組み付け部材４０をネジなどの固定部材６１で取付ける際に、この固定部材６１と係合するボス部２７をラジエータグリル２０の裏面より突出させて形成したボックス形状の延出部２６の先端部２６ｂに備えると共に、延出部２６の根元部である第１部２６ａａの厚みｔａａを延出部２６の先端部２６ｂと接合するボス部２７の接合部の厚みｔｂよりも薄く形成する。 That is, when the assembly member 40 is attached to the radiator grill 20 with a fixing member 61 such as a screw, the box-shaped extension portion formed by projecting the boss portion 27 that engages with the fixing member 61 from the back surface of the radiator grill 20. 26, and the thickness taa of the first portion 26aa, which is the base portion of the extending portion 26, is formed thinner than the thickness tb of the joining portion of the boss portion 27 that joins the leading end portion 26b of the extending portion 26. To do.

この構成により、延出部２６の先端部２６ｂに接合するボス部２７の厚みｔｂを確保できて、ボス部２７における十分な強度を得ることができると共に、ラジエータグリル２０に対する延出部２６の厚みｔａａを薄くしているので、ラジエータグリル２０の表面にヒケができないようにすることができる。 With this configuration, the thickness tb of the boss portion 27 to be joined to the tip portion 26b of the extension portion 26 can be secured, and sufficient strength in the boss portion 27 can be obtained, and the thickness of the extension portion 26 with respect to the radiator grill 20 can be obtained. Since taa is made thin, the surface of the radiator grille 20 can be prevented from sinking.

そして、延出部２６の根元部がラジエータグリル２０の裏面と接合する接合面の面積Ｓ１（図３のクロスハッチング部分）を、ボス部２７の根元部が先端部２６ｂと接合する接合面の面積Ｓ０（図３の斜線ハッチング部分）よりも小さくなるように形成する。 And the area S1 (cross-hatching part of FIG. 3) where the root part of the extension part 26 joins the back surface of the radiator grille 20 is the area of the joint surface where the root part of the boss part 27 joins the tip part 26b. It is formed to be smaller than S0 (the hatched portion in FIG. 3).

この、延出部２６において、ラジエータグリル２０の裏面との接合面の面積Ｓ１を、ボス部２７の先端部２６ｂとの接合面の面積Ｓ０よりも小さくする構成により、ラジエータグリル２０の表面にヒケができないようにすることができる。なお、面積Ｓ１は面積Ｓ０よりは小さいが、延出部２６をラジエータグリル２０の裏面で保持するのに十分な面積を有している上に、ボス部２７が接続する先端部２６ｂとの接合面の面積Ｓ０も十分な面積を有しているので、ボス部２７の強度を十分に確保できる。 In the extended portion 26, the area S 1 of the joint surface with the back surface of the radiator grill 20 is made smaller than the surface area S 0 of the joint surface with the tip end portion 26 b of the boss portion 27. Can not be. Although the area S1 is smaller than the area S0, the area S1 has a sufficient area to hold the extension part 26 on the back surface of the radiator grill 20, and is joined to the tip part 26b to which the boss part 27 is connected. Since the surface area S0 also has a sufficient area, the strength of the boss portion 27 can be sufficiently ensured.

また、これにより、合成樹脂の射出成形でラジエータグリル２０の表面に発生しがちなヒケの発生を防止するために、延出部２６の根元部の第１部２６ａａを薄肉で形成しても、空隙２６ｃを有するボックス構造の採用により、延出部２６とラジエータグリル２０の裏面との接合面の面積Ｓ１を十分大きく確保できるので、固定部材６１が係合するボス部２７を保持する延出部２６の強度を保ちながら、ヒケの発生を防止することができる。 In addition, thereby, in order to prevent the occurrence of sink marks that tend to occur on the surface of the radiator grill 20 by injection molding of synthetic resin, even if the first portion 26aa at the base portion of the extension portion 26 is formed with a thin wall, By adopting the box structure having the gap 26c, a sufficiently large area S1 of the joint surface between the extension portion 26 and the rear surface of the radiator grille 20 can be secured, so that the extension portion that holds the boss portion 27 with which the fixing member 61 is engaged. The occurrence of sink marks can be prevented while maintaining the strength of 26.

また、延出部２６においては、ラジエータグリル２０の裏面との接合面の面積（第１部２６ａａの断面積）Ｓ１よりも、第２部２６ａｂの断面積Ｓ２（図３の斜線ハッチング部分＋クロスハッチング部分）を大きくして構成される。言い換えれば、第２部２６ａｂの第１方向（Ｘ方向）と垂直方向（Ｙ−Ｚ平面内の方向）の厚みｔａｂが、第１部２６ａａの同じ方向（Ｙ−Ｚ平面内の方向）の厚みｔａａと比べて厚くなるように形成する。 In addition, in the extended portion 26, the cross-sectional area S2 of the second portion 26ab (the hatched portion of the hatched portion in FIG. 3 + the cross) is larger than the area S1 (the cross-sectional area of the first portion 26aa) of the radiator grille 20 with the back surface. The hatched portion is made larger. In other words, the thickness tab of the second portion 26ab in the first direction (X direction) and the vertical direction (the direction in the YZ plane) is the same as the thickness of the first portion 26aa in the same direction (the direction in the YZ plane). It is formed to be thicker than taa.

この構成により、第１部２６ａａの厚みｔａａを薄くすることによりラジエータグリル２０の表面にヒケができないようにすると共に、ボス部２７が接合する先端部２６ｂを支える第２部２６ａｂの厚みｔａｂを厚くすることにより、ボス部２７の根元を支える先端部２６ｂを十分な強度の第２部２６ａｂで支持できるようにする。 With this configuration, by reducing the thickness taa of the first portion 26aa, the surface of the radiator grill 20 can be prevented from sinking, and the thickness tab of the second portion 26ab supporting the tip portion 26b to which the boss portion 27 is joined is increased. By doing so, the tip portion 26b that supports the base of the boss portion 27 can be supported by the second portion 26ab having sufficient strength.

また、組み付け部材４０は、ボス部２７の先端に組み付けられた固定部材６１を介してラジエータグリル２０に固定される。この固定部材６１はネジ（スクリュー）などで構成され、ボス孔２７ａにねじ込んで、螺合により固定される。 The assembly member 40 is fixed to the radiator grille 20 via a fixing member 61 assembled to the tip of the boss portion 27. The fixing member 61 is constituted by a screw (screw) or the like, screwed into the boss hole 27a, and fixed by screwing.

また、この実施の形態のラジエータグリル２０では、このラジエータグリル２０に別体グリル３０を組み付けるための係止部２２を備えて構成され、図６に示すように、この係止部２２は、グリル本体２０の裏面に設けられ、空隙２５を有してボックス形状に構成される。この空隙２５を有することで、ラジエータグリル２０を形成する材料の量を低減することができる。 Further, the radiator grill 20 of this embodiment includes a locking portion 22 for assembling the separate grill 30 to the radiator grill 20, and as shown in FIG. It is provided on the back surface of the main body 20 and is configured in a box shape with a gap 25. By having this gap 25, the amount of material forming the radiator grill 20 can be reduced.

この係止部２２は、図６に示すように、別体グリル３０が差し込まれた状態で別体グリル３０の移動を規制する溝部２３に、別体グリル３０の一部３０ａが差し込まれると、この部分３０ａがラジエータグリル２０に固定される。つまり、別体グリル３０の一部３０ａを、その溝部２３に差し込むことで別体グリル３０のＸ方向への移動を規制する。これにより、この部位における別体グリル３０を固定するためのネジなどの固定部材が不要になり、その結果、固定作業が不要になるので、ラジエータグリル２０に対して別体グリル３０の組み付け作業が簡略化され容易となる。 As shown in FIG. 6, when a part 30 a of the separate grill 30 is inserted into the groove 23 that restricts the movement of the separate grill 30 in a state where the separate grill 30 is inserted, This portion 30 a is fixed to the radiator grill 20. That is, by inserting a part 30a of the separate grill 30 into the groove 23, the movement of the separate grill 30 in the X direction is restricted. This eliminates the need for a fixing member such as a screw for fixing the separate grill 30 at this site, and as a result, eliminates the need for a fixing operation, so that the separate grill 30 can be assembled to the radiator grill 20. Simplified and easy.

さらに、この係止部２２は、その先端部（−Ｘ方向から見たときの表面）２２ｂに、ラジエータグリル２０を車両に取り付ける際に使用するクリップ５０を係合して固定するための係合部２４を設けて構成される。この係合部２４は、例えば、クリップ５０が係止部２２のＸ方向と垂直方向（Ｙ−Ｚ平面内の方向：例えばＹ方向やＺ方向）から挿入されたときに、クリップ５０の溝部５１と係合して、クリップ５０を係止部２２に固定できるように構成される。 Further, the engaging portion 22 is engaged with a clip 50 used when attaching the radiator grille 20 to the vehicle at the tip end portion (surface when viewed from the −X direction) 22b. A portion 24 is provided. For example, when the clip 50 is inserted from a direction perpendicular to the X direction of the locking portion 22 (direction in the YZ plane: for example, the Y direction or the Z direction), the engaging portion 24 is a groove portion 51 of the clip 50. And the clip 50 can be fixed to the locking portion 22.

この構成では、係止部２２をボックス形状に形成することより、溝部２３とクリップ５０を固定する係合部２４の形成が容易となり、それぞれの部位の強度も容易に確保できるようになる。また、それと共に、一つの係止部２２において、別体グリル３０とクリップ５０の二つの部品２０、５０を組み付けて固定できるので、部品点数を減少することができる。 In this configuration, since the locking portion 22 is formed in a box shape, it is easy to form the engaging portion 24 that fixes the groove portion 23 and the clip 50, and the strength of each portion can be easily secured. At the same time, since the two parts 20 and 50 of the separate grill 30 and the clip 50 can be assembled and fixed in one locking portion 22, the number of parts can be reduced.

そして、このクリップ５０により、ラジエータグリル２０は、別体グリル３０を組み付けた状態で車両に組み付けることができるようになる。この組み付けでは、クリップ５０が車両側の取り付け部と係合して固定されることにより、ラジエータグリル２０は車両に固定されることになる。 The clip 50 allows the radiator grill 20 to be assembled to the vehicle with the separate grill 30 assembled. In this assembly, the radiator grill 20 is fixed to the vehicle by the clip 50 engaging and fixing with the mounting portion on the vehicle side.

別体グリル３０は、図１及び図２に示すように、四隅の内の一か所が係止部２２の溝部２３で固定されると共に、四隅の内の三か所が挿入穴３１でネジ（スクリュー）等の固定部材６０によりラジエータグリル２０に設けられたボス部２７に組み付けられる。そして、更に、組み付け部材４０が二か所の挿入穴４１でネジ等の固定部材６１によりグリル本体２０に設けられたボス部２７に固定される。これにより、ラジエータグリル２０の組み付けが完了する。 As shown in FIGS. 1 and 2, the separate grill 30 is fixed at one of the four corners by the groove portion 23 of the locking portion 22, and at three of the four corners by the insertion holes 31. A fixing member 60 such as a (screw) is attached to the boss portion 27 provided on the radiator grill 20. Further, the assembly member 40 is fixed to the boss portion 27 provided in the grill main body 20 by the fixing members 61 such as screws at the two insertion holes 41. Thereby, the assembly of the radiator grille 20 is completed.

そして、本発明の実施の形態の車両は、車両の前部に備えられたエンジンルームの前方で、車両に組み付けられる、上記のラジエータグリル２０と、このラジエータグリル２０の後方で且つエンジンルーム内に配置されたラジエータと、このラジエータの前方に配置され、ラジエータグリル２０の裏面に備えられたボス部２７に組み付けられる組み付け部材４０とを備えて構成される。 The vehicle according to the embodiment of the present invention includes the radiator grill 20 assembled to the vehicle in front of the engine room provided at the front of the vehicle, the rear of the radiator grill 20 and in the engine room. The radiator is disposed, and the assembly member 40 is disposed in front of the radiator and is assembled to the boss portion 27 provided on the back surface of the radiator grill 20.

上記の構成の本発明のラジエータグリル２０と車両によれば、車両に備えらえるラジエータグリル２０において、ラジエータグリル２０を車両に組み付けた際に、ネジ等の固定部材６１が螺合され、ラジエータグリル２０の裏面に配置されたボス部２７において、延出部２６がラジエータグリル２０の裏面との接合する部分の厚みｔａａを、ボス部１７が延出部２６の先端部２６ｂと接合する部分の厚みｔｂよりも薄く形成して構成するので、ボス部２７の強度が確保できると共に、ラジエータグリル２０の表面にヒケができないようにすることができる。 According to the radiator grill 20 and the vehicle of the present invention configured as described above, in the radiator grill 20 provided in the vehicle, when the radiator grill 20 is assembled to the vehicle, the fixing member 61 such as a screw is screwed and the radiator grille is screwed. In the boss portion 27 arranged on the back surface of the boss 20, the thickness taa of the portion where the extending portion 26 joins to the back surface of the radiator grill 20 is set, and the thickness of the portion where the boss portion 17 joins the tip portion 26 b of the extending portion 26. Since it is formed to be thinner than tb, the strength of the boss portion 27 can be secured and the surface of the radiator grill 20 can be prevented from sinking.

さらに、第１方向（Ｘ方向）と垂直方向（Ｙ−Ｚ平面内の方向）の厚みに関して、第１部分２６ａａの厚みｔａａと比べて第２部２６ａｂの厚みｔａｂを厚くしたり、延出部２６の第２部２６ａｂの断面積Ｓ２を、延出部２６とラジエータグリル２０の裏面との接合面の面積（第１部２６ａａの断面積）Ｓ１の方よりも大きくしたりすることで、よりボス部２７の強度を確保できる。 Furthermore, regarding the thickness in the first direction (X direction) and the vertical direction (direction in the YZ plane), the thickness tab of the second portion 26ab is made thicker than the thickness taa of the first portion 26aa, or the extension portion 26 by making the cross-sectional area S2 of the second portion 26ab 26 larger than the area of the joint surface between the extending portion 26 and the back surface of the radiator grill 20 (the cross-sectional area of the first portion 26aa) S1. The strength of the boss portion 27 can be ensured.

なお、ここで説明した、本発明の延出部２６及びボス部２７の構造は、ラジエータグリル２０にシール部材４０を組み付ける以外でも使用することができる。 Note that the structure of the extending portion 26 and the boss portion 27 of the present invention described here can be used in addition to assembling the seal member 40 to the radiator grill 20.
