Description

本発明は、車両用クロスカービームに関する。   The present invention relates to a vehicular cross car beam.

通常、クロスカービームは、車幅方向の両端を車体側部のピラー部材やダッシュパネルに固定され且つ前側がダッシュパネルに固定されている強度部材で、インストルメントパネル、エアバッグ装置、空調装置、ステアリング装置等を支持している。つまり、このクロスカービームは剛性を必要とするため、機械的強度の高い材料を用いて成形されるのが一般で、鋼（スチール）やマグネシウム等の高剛性材料によって成形している（例えば、特許文献１参照）。
特開２００１−３２８４２１公報 Usually, the cross car beam is a strength member in which both ends in the vehicle width direction are fixed to the pillar member and the dash panel on the side of the vehicle body, and the front side is fixed to the dash panel. Supports a steering device and the like. In other words, since this cross car beam requires rigidity, it is generally formed using a material having high mechanical strength, and is formed using a highly rigid material such as steel (steel) or magnesium (for example, Patent Document 1).
JP 2001-328421 A

しかしながら、前記従来の技術による車両用クロスカービームは、鋼（スチール）を用いて形成した場合には、クロスカービーム自体の重量が増加し、燃費を悪化させるという問題がある。また、マグネシウムを用いて形成した場合には、クロスカービームの材料コストが高くなり、製造原価高騰の一原因になるという問題がある。   However, when the crosscar beam for a vehicle according to the conventional technique is formed using steel, there is a problem that the weight of the crosscar beam itself is increased and fuel consumption is deteriorated. Further, when formed using magnesium, there is a problem that the material cost of the cross car beam becomes high, which causes a rise in manufacturing cost.

また、車両用クロスカービームを合成樹脂で成形した場合には、例えば、運転席側におけるステアリング支持部近傍の剛性が前記鋼（スチール）やマグネシウムで成形する場合に比較して低下するおそれがあり、ステアリング装置、インストルメントパネル等、前記した部材の支持剛性が不足するおそれがある。   In addition, when the vehicle cross car beam is formed of synthetic resin, for example, the rigidity in the vicinity of the steering support portion on the driver's seat side may be reduced as compared with the case of forming the steel (steel) or magnesium. There is a possibility that the support rigidity of the above-described members such as a steering device and an instrument panel is insufficient.

そこで、本発明は、重量の増加や材料コストの上昇を伴うことなく、ステアリング装置等を支持できる機械的強度を向上させることができる車両用クロスカービームを提供する。   Therefore, the present invention provides a crosscar beam for a vehicle that can improve the mechanical strength capable of supporting a steering device or the like without increasing the weight or the material cost.

前記目的を達するために、請求項１に記載の発明は、車両用クロスカービームであって、運転席側から助手席側にかけて車幅方向に延設した合成樹脂製の骨部材と、該骨部材における運転席側の部位の外周側に密接して巻回してなり且つ前記骨部材より強度が高い合成樹脂製の繊維状部材とより構成されてなり、該骨部材の成形時に型内に前記繊維状部材が予め配されてなることを特徴とする。   In order to achieve the above object, the invention according to claim 1 is a crosscar beam for a vehicle, and is a bone member made of a synthetic resin extending in a vehicle width direction from a driver seat side to a passenger seat side, and the bone The member is composed of a fibrous member made of a synthetic resin that is wound tightly around the outer peripheral side of the part on the driver's seat side of the member and has a strength higher than that of the bone member. A fibrous member is arranged in advance.

請求項２に記載の発明は、請求項１に記載の車両用クロスカービームであって、前記繊維状部材は、前記骨部材の長手方向に沿った第一方向と、該第一方向に略直角な第二方向にそれぞれ並列に配されて編まれてなることを特徴とする。   Invention of Claim 2 is the crosscar beam for vehicles of Claim 1, Comprising: The said fibrous member is the 1st direction along the longitudinal direction of the said bone member, and is substantially in this 1st direction. It is characterized by being knitted in parallel with each other in a perpendicular second direction.

請求項３に記載の発明は、請求項２に記載の車両用クロスカービームであって、前記第一方向及び第二方向に配されてなる繊維状部材間には、前記骨部材が成形時に浸入可能な隙間が形成されてなることを特徴とする。   Invention of Claim 3 is the crosscar beam for vehicles of Claim 2, Comprising: Between the fibrous members arranged by said 1st direction and 2nd direction, the said bone member is at the time of shaping | molding. An intrusionable gap is formed.

請求項４に記載の発明は、前記請求項１〜３のいずれか１項に記載の車両用クロスカービームであって、前記骨部材における運転席側の部位の外周側には、前記繊維状部材が係合可能なる突起が形成されてなることを特徴とする。   Invention of Claim 4 is the crosscar beam for vehicles of any one of the said Claims 1-3, Comprising: On the outer peripheral side of the site | part of the driver's seat side in the said bone member, the said fibrous form Protrusions that can be engaged with members are formed.

請求項５に記載の発明は、前記請求項１〜４のいずれか１項に記載の車両用クロスカービームであって、前記繊維状部材は、予め網状に形成されてなるカーボン繊維と、該カーボン繊維を挟み込んで加熱することにより前記カーボン線維の周りを包む合成樹脂部材とより構成したことを特徴とする。   Invention of Claim 5 is the crosscar beam for vehicles of any one of the said Claims 1-4, Comprising: The said fibrous member is carbon fiber formed in mesh shape beforehand, and this It is characterized by comprising a synthetic resin member that wraps around the carbon fiber by sandwiching and heating the carbon fiber.

請求項１に記載の発明によれば、運転席側の部位を骨部材とこの骨部材の外周側に密接状態で巻回した繊維状部材とからなる二重管構造に構成しているため、最も強度が必要とされる部位を補強することにより、材料コストの上昇や重量の増加をほとんど伴うことなく、クロスカービーム全体の強度をも効率的に向上させることができる。また、骨部材の成形時に型内で繊維状部材が骨部材に一体になるため、取付け部材などが不要となり、原価の高騰がないことになる。   According to the first aspect of the present invention, because the driver's seat side portion is configured in a double tube structure including a bone member and a fibrous member wound in close contact with the outer peripheral side of the bone member, By reinforcing the portion where the most strength is required, the strength of the entire crosscar beam can be efficiently improved with almost no increase in material cost and weight. Further, since the fibrous member is integrated with the bone member in the mold at the time of forming the bone member, an attachment member or the like becomes unnecessary, and the cost does not increase.

請求項２に記載の発明によれば、繊維状部材は、前記骨部材の長手方向に沿った第一方向と、該第一方向に略直角な第二方向にそれぞれ並列に配されて編まれてなるため、長尺方向、即ち第一方向に延びる繊維状部材は長ければ長いほど剛性が著しく向上し、クロスカービーム全体の強度を効率的に向上させることができる。   According to the invention described in claim 2, the fibrous member is knitted by being arranged in parallel in a first direction along the longitudinal direction of the bone member and in a second direction substantially perpendicular to the first direction. Therefore, the longer the fibrous member extending in the longitudinal direction, that is, the first direction, the remarkably improved rigidity and the strength of the entire crosscar beam can be improved efficiently.

請求項３に記載の発明によれば、第一方向及び第二方向に配されてなる繊維状部材間には、前記骨部材が成形時に浸入可能な隙間が形成されてなるため、骨部材の外周に溶融する溶融樹脂が浸入して繊維状部材と結合され、クロスカービーム全体の強度をより効率的に向上させることができる。   According to the third aspect of the present invention, a gap is formed between the fibrous members arranged in the first direction and the second direction so that the bone member can enter during molding. The molten resin that melts on the outer periphery enters and is joined to the fibrous member, so that the strength of the entire cross car beam can be improved more efficiently.

請求項４に記載の発明によれば、骨部材における運転席側の部位の外周側には、前記繊維状部材が係合可能なる突起が形成されてなるため、クロスカービームの運転席側、特にステアリング支持部近傍の繊維状部材が突起により保持されて位置移動せず、クロスカービームの強度を大幅に向上させることができる。   According to the fourth aspect of the present invention, since the protrusion on which the fibrous member can be engaged is formed on the outer peripheral side of the portion on the driver seat side in the bone member, the driver seat side of the cross car beam, In particular, the fibrous member in the vicinity of the steering support portion is held by the protrusion and does not move, and the strength of the cross car beam can be greatly improved.

請求項５に記載の発明によれば、前記繊維状部材は、予め網状に形成されてなるカーボン繊維と、該カーボン繊維を挟み込んで加熱することにより前記カーボン線維の周りを包む合成樹脂部材とより構成したため、クロスカービームの骨部材を型内で成形する際に予め繊維状部材を挿入するが、マット状の繊維状部材の合成樹脂が骨部材の溶融樹脂に溶け込み易くなり、骨部材と繊維状部材との接着強度が高くなり、連続した繊維がインサートされた形となるから強度は非常に大きくなる。   According to the invention described in claim 5, the fibrous member includes a carbon fiber formed in a net shape in advance, and a synthetic resin member that wraps around the carbon fiber by sandwiching and heating the carbon fiber. Since the fiber member is inserted in advance when the cross car beam bone member is molded in the mold, the synthetic resin of the mat-like fiber member is easily dissolved in the molten resin of the bone member. Since the adhesive strength with the shaped member is increased and a continuous fiber is inserted, the strength is extremely increased.

重量の増加や材料コストの上昇を伴うことなく、ステアリング装置等を支持できる機械的強度を向上させることができる車両用クロスカービームを提供する、という目的を、運転席側から助手席側にかけて車幅方向に延設した合成樹脂製の骨部材と、該骨部材における運転席側の部位の外周側に密接して巻回してなり且つ前記骨部材より強度が高い合成樹脂製の繊維状部材とより構成されてなり、該骨部材の成形時に型内に前記繊維状部材が予め配されてなることにより実現した。以下、本発明の最良の実施形態を図面に基づいて説明する。   Vehicles from the driver's side to the passenger's side aim to provide a vehicle cross car beam that can improve the mechanical strength that can support the steering device etc. without increasing the weight or increasing the material cost. A synthetic resin-made bone member extending in the width direction, and a synthetic resin-made fibrous member formed by being closely wound around the outer peripheral side of the driver seat side portion of the bone member and having higher strength than the bone member; This was realized by arranging the fibrous member in advance in the mold when the bone member was molded.

The cross car beam 3 includes a synthetic resin bone member 28 made of nylon and FRP extending in the vehicle width direction from the driver seat side to the passenger seat side, and an outer peripheral side of the bone member 28 on the driver seat side. And a fibrous member 29 made of a synthetic resin and made of a carbon fiber made of carbon fiber having a strength higher than that of the bone member 28.

前記骨部材２８は、上部側の断面略逆Ｕ字状の半割部材３１と、下部側の断面略Ｕ字状の半割部材３２とからなり、これら半割部材３１，３２の長手方向の両端部は、縦壁３１ａ，３２ａにより塞がれている。そして、上部側の半割部材３１における車幅方向外側部分の上面には、図１に示すベント吹き出し口２２及び図示しないセンタ吹き出し口に接続される上方に延びるフランジ２３ａ、２４ａによって囲まれてなる開口２３、２４が一体に形成されている。前記開口２４のすぐ運転席側に寄った位置の骨部材２８には、前記支持スティ１３に結合されるリブ２５が支持されている。前記取付フランジ９，９ａは、前記骨部材２８の助手席側（左側）と運転席側（右側）との端部に、合成樹脂によりそれぞれ鋳ぐるみ成形されている。   The bone member 28 includes a half member 31 having a substantially inverted U-shaped cross section on the upper side and a half member 32 having a substantially U-shaped cross section on the lower side. Both end portions are closed by the vertical walls 31a and 32a. And the upper surface of the vehicle width direction outer side part in the half member 31 on the upper side is surrounded by flanges 23a, 24a extending upward connected to the vent outlet 22 shown in FIG. 1 and a center outlet (not shown). Openings 23 and 24 are integrally formed. A rib 25 coupled to the support stay 13 is supported on the bone member 28 at a position close to the driver's seat side of the opening 24. The mounting flanges 9, 9 a are casted with synthetic resin at the ends of the bone member 28 on the passenger seat side (left side) and the driver seat side (right side).

前記繊維状部材２９は、前記骨部材２８の長手方向に沿った第一方向３５と、該第一方向３５に略直角な第二方向３６にそれぞれ複数の合成樹脂繊維により並列に配されて編まれてなるもので、該繊維状部材２９の第一方向３５及び第二方向３６間には、前記骨部材２８が成形時に浸入可能な隙間３７が形成されてなると共に前記骨部材２８における運転席側の部位の外周側には、前記繊維状部材２９が係合可能なる突起３８が複数突設形成されてなる。前記繊維状部材２９の繊維は、長ければ長いほど絡み量が多くなり、剛性が上がる。出願人に於いて確認したところ、長ければといっても最長で数ミリのイメージである。   The fibrous member 29 is arranged in parallel with a plurality of synthetic resin fibers in a first direction 35 along the longitudinal direction of the bone member 28 and a second direction 36 substantially perpendicular to the first direction 35, respectively. A gap 37 is formed between the first direction 35 and the second direction 36 of the fibrous member 29 so that the bone member 28 can enter during molding, and a driver's seat in the bone member 28 is formed. A plurality of protrusions 38 that can be engaged with the fibrous member 29 are formed on the outer peripheral side of the side portion. The longer the fibers of the fibrous member 29, the greater the amount of entanglement and the higher the rigidity. The applicant confirmed that the longest image is several millimeters at most.

前記リブ２５の下部側には、支持スティ１３が締結固定されるための支持スティ用取付部２６が更に下方に突出形成されている。前記支持部５は、一対上方に向けて開放した有底の箱形状をなす。   On the lower side of the rib 25, a support stay attaching portion 26 for fastening and fixing the support stay 13 is formed to protrude further downward. The said support part 5 makes | forms the box shape with a bottom opened toward a pair upper direction.

次に、クロスカービーム３の成形方法を簡単に説明する。   Next, a method for forming the cross car beam 3 will be briefly described.

まず、骨部材２８を成形する。予め、図４に示す上部側の半割部材３１と下部側の半割部材３２とを別々に合成樹脂により射出成形し、これらの周縁部同士３３，３４を互いに振動溶着させることによって、内部が中空の骨部材２８を成形する。   First, the bone member 28 is formed. In advance, the upper half member 31 and the lower half member 32 shown in FIG. 4 are separately injection-molded with synthetic resin, and these peripheral portions 33 and 34 are vibration welded to each other, so that the inside A hollow bone member 28 is formed.

次いで、骨部材２８の左右両端部の外周側に、取付ブラケット９，９ａを合成樹脂により鋳ぐるむと共に骨部材２８の運転席側の外周に繊維状部材２９を覆う。この繊維状部材２９は、骨部材２８の突起３８に引っ掛ける。図５に示すように、上型３９、下型４０及びサイド型４１から構成された金型４２を用いて鋳ぐるむことができる。   Next, the mounting brackets 9 and 9a are casted with synthetic resin on the outer peripheral sides of the left and right ends of the bone member 28, and the fibrous member 29 is covered on the outer periphery of the bone member 28 on the driver seat side. The fibrous member 29 is hooked on the protrusion 38 of the bone member 28. As shown in FIG. 5, casting can be performed using a mold 42 including an upper mold 39, a lower mold 40, and a side mold 41.

予め成形された前記骨部材２８及び該骨部材２８の外周を覆った繊維状部材２９を金型４２内に収容し、上型３９、下型４０及びサイド型４１を移動させて金型４２を閉成すると、図５に示すように、骨部材２８と金型４２の内面との間に３〜５ミリ程度のキャビティ４３が形成される。上型３９に設けられた湯口４４から前記キャビティ４３内に溶融樹脂４５を注入して該溶融樹脂４５をキャビティ４３内に充填させ、この状態で溶融樹脂４５を硬化させることによって、骨部材２８及び繊維状部材２９の外周側に第二筒状体４６を鋳ぐるむことができる。該第二筒状体４６には、前記支持部５が同時に鋳ぐるむことができる。こののち、矢印に示す方向に上型３９、下型４０及びサイド型４１を移動させることによって金型４２を開くと、クロスカービーム３が得られる。ここで、前記溶融樹脂４５は、骨部材２８を構成する樹脂よりも高い強度を有するものが好ましい。   The bone member 28 and the fibrous member 29 covering the outer periphery of the bone member 28 are accommodated in a mold 42, and the upper mold 39, the lower mold 40 and the side mold 41 are moved to move the mold 42. When closed, a cavity 43 of about 3 to 5 mm is formed between the bone member 28 and the inner surface of the mold 42 as shown in FIG. By injecting the molten resin 45 into the cavity 43 from the gate 44 provided in the upper mold 39 and filling the cavity 43 with the molten resin 45, the molten resin 45 is cured in this state, whereby the bone member 28 and The second cylindrical body 46 can be cast on the outer peripheral side of the fibrous member 29. The support portion 5 can be cast on the second cylindrical body 46 at the same time. After that, when the mold 42 is opened by moving the upper mold 39, the lower mold 40, and the side mold 41 in the direction indicated by the arrows, the cross car beam 3 is obtained. Here, the molten resin 45 preferably has higher strength than the resin constituting the bone member 28.

従って、本実施例によれば、運転席側の部位を骨部材２８とこの骨部材２８の外周側に密接状態で巻回した繊維状部材２９とからなる二重管構造に構成しているため、最も強度が必要とされる部位であるステアリングホイール４の支持部５を補強することにより、材料コストの上昇や重量の増加をほとんど伴うことなく、クロスカービーム３全体の強度をも効率的に向上させることができる。また、骨部材２８の成形時に金型４２内で繊維状部材２９が骨部材２８に一体になるため、取付け部材などが不要となり、原価の高騰がないことになる。   Therefore, according to the present embodiment, the portion on the driver's seat side is configured as a double tube structure including the bone member 28 and the fibrous member 29 wound in close contact with the outer peripheral side of the bone member 28. By reinforcing the support portion 5 of the steering wheel 4, which is the part that requires the most strength, the strength of the entire cross car beam 3 can be efficiently increased with almost no increase in material cost or weight. Can be improved. Further, since the fibrous member 29 is integrated with the bone member 28 in the mold 42 when the bone member 28 is molded, an attachment member or the like is not required, and the cost is not increased.

また、繊維状部材２９は、前記骨部材２８の長手方向に沿った第一方向３５と、該第一方向３５に略直角な第二方向３６にそれぞれ並列に配されて編まれてなるため、長尺方向、即ち第一方向３５に延びる繊維状部材２９は長ければ長いほど剛性が著しく向上し、クロスカービーム３全体の強度を効率的に向上させることができる。   Further, since the fibrous member 29 is knitted by being arranged in parallel in the first direction 35 along the longitudinal direction of the bone member 28 and the second direction 36 substantially perpendicular to the first direction 35, respectively. The longer the fibrous member 29 extending in the longitudinal direction, that is, the first direction 35, the remarkably improved rigidity, and the strength of the entire cross car beam 3 can be improved efficiently.

第一方向３５及び第二方向３６に配されてなる繊維状部材２９の交叉された間には、前記骨部材２８が成形時に浸入可能な隙間３７が形成されてなるため、繊維状部材２９の隙間３７に骨部材２８の外周に溶融する溶融樹脂４５が浸入して繊維状部材２９と結合され、クロスカービーム３全体の強度をより効率的に向上させることができる。   A gap 37 is formed between the fibrous members 29 arranged in the first direction 35 and the second direction 36 so that the bone member 28 can enter during molding. The molten resin 45 that melts on the outer periphery of the bone member 28 enters the gap 37 and is joined to the fibrous member 29, so that the strength of the entire cross car beam 3 can be improved more efficiently.

骨部材２８における運転席側の部位の外周側には、前記繊維状部材２９が係合可能なる突起３８が形成されてなるため、クロスカービーム３の運転席側、特にステアリングホイール４の支持部５近傍の繊維状部材２９が突起３８により保持されて左右方向に位置を移動せず、クロスカービーム３の強度を大幅に向上させることができる。このため、車幅方向の中央側の下面にＨＶＡＣに連結される吸い込み口７を形成しても、クロスカービーム３全体の強度を保持することができる。   On the outer peripheral side of the part on the driver's seat side of the bone member 28, a projection 38 that can be engaged with the fibrous member 29 is formed, so that the driver's seat side of the cross car beam 3, particularly the support part of the steering wheel 4 is provided. The fibrous members 29 in the vicinity of 5 are held by the projections 38 and do not move in the left-right direction, and the strength of the cross car beam 3 can be greatly improved. For this reason, even if the suction port 7 connected to the HVAC is formed on the lower surface on the center side in the vehicle width direction, the strength of the entire cross car beam 3 can be maintained.

さらに、クロスカービーム３には、例えばステアリングホイール４の支持部５を介して下方に向けて荷重が入力されるが、この荷重が取付フランジ９，９ａ、リブ２５及び支持スティ用取付部２６に均等に分散される。なお、取付フランジ９，９ａも骨部材２８に同時に鋳ぐるむが、第二筒状体４６よりも剛性を必要としないため、鋳ぐるみの範囲が小さくてすむ。さらに、エアバックの収容用ケーシング６を半割部材３２に一体成形しているため、別途の部材を設ける必要がない。   Furthermore, a load is input to the cross car beam 3 downward, for example, via the support portion 5 of the steering wheel 4, and this load is applied to the attachment flanges 9, 9 a, the rib 25 and the support stay attachment portion 26. Evenly distributed. Although the mounting flanges 9 and 9a are cast on the bone member 28 at the same time, the rigidity of the mounting flanges 9 and 9a is less than that of the second cylindrical body 46, so that the range of the cast-in can be reduced. Further, since the airbag housing casing 6 is integrally formed with the half member 32, there is no need to provide a separate member.

図６乃至図９は、本願発明の第２実施例を示す図である。第１実施例と主に異なる点は、繊維状部材の構成であり、他は同じなので、繊維状部材についてのみ説明し、他を省略する。符号５０は、第２実施例の繊維状部材で、該繊維状部材５０は、予め網状に形成されてなるカーボン繊維５１と、該カーボン繊維５１を挟み込んで加熱することにより前記カーボン線維５１の周りを機械的に包むナイロンなど熱可塑性樹脂などの合成樹脂部材５２とより構成したもので、図６に示す状態で熱を加えると共に加圧することで、図７に示すマット状の繊維状部材５０が形成される。   6 to 9 are views showing a second embodiment of the present invention. The main difference from the first embodiment is the configuration of the fibrous member, and the others are the same, so only the fibrous member will be described and the others will be omitted. Reference numeral 50 denotes a fibrous member according to the second embodiment. The fibrous member 50 includes a carbon fiber 51 formed in a net shape in advance, and the carbon fiber 51 around the carbon fiber 51 by sandwiching and heating the carbon fiber 51. 7 and a synthetic resin member 52 such as a thermoplastic resin such as nylon, and the mat-like fibrous member 50 shown in FIG. 7 is formed by applying heat and pressing in the state shown in FIG. It is formed.

このマット状の繊維状部材５０を適宜の大きさに裁断して、骨部材２８の運転席側の外周面に接着し、図８に示すように、骨部材２８と金型４２の内面との間に３〜５ミリ程度のキャビティ４３が形成される。上型３９に設けられた湯口４４（図５参照）から前記キャビティ４３内に溶融樹脂４５を注入して該溶融樹脂４５をキャビティ４３内に充填させ、この状態で溶融樹脂４５を硬化させることによって、骨部材２８及び繊維状部材５０の外周側に第二筒状体４６を鋳ぐるむことができる。   The mat-like fibrous member 50 is cut into an appropriate size and adhered to the outer peripheral surface of the bone member 28 on the driver's seat side, and as shown in FIG. A cavity 43 of about 3 to 5 mm is formed between them. By injecting the molten resin 45 into the cavity 43 from the gate 44 (see FIG. 5) provided in the upper die 39, filling the molten resin 45 into the cavity 43, and curing the molten resin 45 in this state. The second cylindrical body 46 can be cast on the outer peripheral sides of the bone member 28 and the fibrous member 50.

こののち、図５に示す矢印に示す方向に上型３９、下型４０及びサイド型４１を移動させることによって金型４２を開くと、クロスカービーム３が得られる。尚、図９の符号５３は、繊維状部材５０の合成樹脂部材５２及び溶融樹脂４５が溶けて接着されている部分である。   After that, when the mold 42 is opened by moving the upper mold 39, the lower mold 40, and the side mold 41 in the direction shown by the arrows in FIG. 5, the crosscar beam 3 is obtained. 9 is a portion where the synthetic resin member 52 and the molten resin 45 of the fibrous member 50 are melted and bonded.

従って、前記繊維状部材５０は、予め網状に形成されてなるカーボン繊維５１と、該カーボン繊維５１を挟み込んで加熱することにより前記カーボン線維５１の周りを包む合成樹脂部材５２とより構成したため、クロスカービーム３の骨部材２８を金型４２内で成形する際に予め繊維状部材５０を挿入するが、マット状の繊維状部材５０の合成樹脂部材５２が骨部材２８の溶融樹脂４５に溶け込み易くなり、骨部材２８と繊維状部材５０との接着強度が高くなり、連続した繊維がインサートされた形となるから強度は非常に大きくなる。   Accordingly, the fibrous member 50 is composed of carbon fibers 51 formed in a net shape in advance and a synthetic resin member 52 that wraps around the carbon fibers 51 by sandwiching and heating the carbon fibers 51. The fibrous member 50 is inserted in advance when the bone member 28 of the car beam 3 is molded in the mold 42, but the synthetic resin member 52 of the mat-like fibrous member 50 is easily dissolved in the molten resin 45 of the bone member 28. Thus, the bonding strength between the bone member 28 and the fibrous member 50 is increased, and the strength is extremely increased because a continuous fiber is inserted.

以上の実施例では、クロスカービーム３の運転席側は、図上右側として説明したが、運転席側とは、ステアリングホイールを支持する部分が配設される位置を意味するのであるから、左ハンドル車など左側でも良いし、車両の中央に設けられるものでも良い。   In the above embodiment, the driver's seat side of the cross car beam 3 has been described as the right side in the figure, but the driver's seat side means a position where a portion that supports the steering wheel is disposed. It may be on the left side such as a steering wheel vehicle, or may be provided in the center of the vehicle.
