Ribs 84 are formed (see also FIG. 5). The rear end 84L of the upper rib 84 is connected to the reinforcing rib 72A, and the front end 84R extends to the upper side of the fastening portion 60D (fastening hole 62D).

次に本実施形態の作用及び効果について説明する。   Next, the operation and effect of this embodiment will be described.

樹脂製(本実施形態では炭素繊維強化プラスチック製)のドアインナパネル20の開口部22の外縁部24における締結部60A(締結孔62A)及び締結部60B(締結孔62B)の周囲には、それぞれ締結部60A、60B(締結孔62A、62B)を囲むように平行して補強リブ70A、72A及び補強リブ70B、72Bが設けられている。よって、締結部60A、60B(締結孔62A、62B)の周囲の支持剛性が高くなる。   Around the fastening portion 60A (fastening hole 62A) and the fastening portion 60B (fastening hole 62B) at the outer edge 24 of the opening 22 of the door inner panel 20 made of resin (made of carbon fiber reinforced plastic in this embodiment), respectively. Reinforcing ribs 70A and 72A and reinforcing ribs 70B and 72B are provided in parallel so as to surround the fastening portions 60A and 60B (fastening holes 62A and 62B). Therefore, the support rigidity around the fastening portions 60A and 60B (fastening holes 62A and 62B) is increased.

また、開口部22の外縁部24における締結部60A(締結孔62A)と締結部60B(締結孔62B)とを結ぶ仮想線P1の車両前後方向後側(径方向外側)に補強リブ72Aと補強リブ72Bとを連結する連結リブ80が設けられている。よって、外縁部24の剛性が効果的に高くなる。   Further, the reinforcing rib 72A and the reinforcing rib 72A are reinforced on the rear side in the vehicle front-rear direction (radially outward) of the virtual line P1 connecting the fastening portion 60A (fastening hole 62A) and the fastening portion 60B (fastening hole 62B) in the outer edge portion 24 of the opening portion 22. A connecting rib 80 that connects the rib 72B is provided. Therefore, the rigidity of the outer edge portion 24 is effectively increased.

更に、本実施形態では、外縁部24における締結部60B(締結孔62B)と締結部60C(締結孔62C)とを結ぶ仮想線P2の車両上下方向下側には下側リブ82が形成され、締結部60A(締結孔62A)と締結部60D(締結孔62D)とを結ぶ仮想線P3の車両上下方向上側には上側リブ84が形成されている。よって、外縁部24の剛性が更に効果的に高くなる。   Further, in the present embodiment, a lower rib 82 is formed on the lower side in the vehicle vertical direction of a virtual line P2 connecting the fastening portion 60B (fastening hole 62B) and the fastening portion 60C (fastening hole 62C) in the outer edge portion 24, An upper rib 84 is formed on the upper side in the vehicle vertical direction of a virtual line P3 that connects the fastening portion 60A (fastening hole 62A) and the fastening portion 60D (fastening hole 62D). Therefore, the rigidity of the outer edge portion 24 is further effectively increased.

このように締結部60A、60Bの支持剛性が高くなると共に外縁部24の剛性が効果的に高くなるので、スピーカ50の振動、特に低周波振動がドアインナパネル20を介してサイドドア12全体に伝達されることが効果的に抑制され、これによりスピーカ50の振動、特に低周波振動に起因する不快な音の発生が抑制される。   As described above, since the support rigidity of the fastening portions 60A and 60B is increased and the rigidity of the outer edge portion 24 is effectively increased, vibration of the speaker 50, particularly low-frequency vibration, is transmitted to the entire side door 12 via the door inner panel 20. The transmission is effectively suppressed, thereby suppressing the generation of unpleasant sound due to the vibration of the speaker 50, particularly the low frequency vibration.

なお、仮に連結リブ80が締結部60A(締結孔62A)と締結部60B(締結孔62B)とを結ぶ仮想線P1の車両前後方向前側(径方向内側)に設けられている場合は、仮想線P1の外側の外縁部24が撓み易く振動が伝達されやすい。よって、仮想線P1の車両前後方向前側(径方向内側)に連結リブ80を設けた場合は、振動伝達を効果的に抑制することができない。   If the connecting rib 80 is provided on the front side in the vehicle front-rear direction (radially inward) of the virtual line P1 connecting the fastening portion 60A (fastening hole 62A) and the fastening portion 60B (fastening hole 62B), the virtual line The outer edge 24 on the outer side of P1 is easily bent and vibrations are easily transmitted. Therefore, when the connecting rib 80 is provided on the front side in the vehicle front-rear direction (the radially inner side) of the virtual line P1, vibration transmission cannot be effectively suppressed.

しかし、本実施形態では、連結リブ80は、締結部60A(締結孔62A)と締結部60B(締結孔62B)とを結ぶ仮想線P1の結ぶ車両前後方向後側(径方向外側)に設けられているので、振動伝達を効果的に抑制することができる。なお、下側リブ82及び上側リブ84も同様にそれぞれ仮想線P2、P3の径方向外側に形成されているので、振動伝達を効果的に抑制することができる。   However, in the present embodiment, the connecting rib 80 is provided on the rear side in the vehicle front-rear direction (radially outward) where the virtual line P1 connecting the fastening portion 60A (fastening hole 62A) and the fastening portion 60B (fastening hole 62B) is connected. Therefore, vibration transmission can be effectively suppressed. Since the lower rib 82 and the upper rib 84 are also formed on the radially outer sides of the virtual lines P2 and P3, respectively, vibration transmission can be effectively suppressed.

また、補強リブ70A、72A、70B、72B及び連結リブ80によってドアインナパネル20全体の剛性が向上する。更に、本実施形態では、下側リブ82及び上側リブ84が形成されているので、更にドアインナパネル20全体の剛性が向上する。   Further, the rigidity of the door inner panel 20 as a whole is improved by the reinforcing ribs 70A, 72A, 70B, 72B and the connecting rib 80. Furthermore, in this embodiment, since the lower rib 82 and the upper rib 84 are formed, the rigidity of the entire door inner panel 20 is further improved.

また、ドアインナパネル20は樹脂(本実施形態では炭素繊維強化プラスチック)で構成されており、例えば金属パネルでは成形できない複雑な形状を容易に成形することができる。つまり、ドアインナパネル20に、補強リブ70A、72A、70B、72B、連結リブ80、下側リブ82及び上側リブ84を容易に設けることができる。   Moreover, the door inner panel 20 is comprised with resin (carbon fiber reinforced plastic in this embodiment), for example, the complicated shape which cannot be shape | molded with a metal panel can be shape | molded easily. That is, the reinforcing ribs 70A, 72A, 70B, 72B, the connecting rib 80, the lower rib 82, and the upper rib 84 can be easily provided on the door inner panel 20.

また、炭素繊維強化プラスチックは、金属パネルと比較して振動減衰率が高く高剛性であるので、スピーカ50の支持素材としては好適である。よって、スピーカ50の振動伝達を抑制することで不快な音を抑制し、且つレスポンスの良い音響効果を得ることができる。   Carbon fiber reinforced plastic is suitable as a support material for the speaker 50 because it has a high vibration damping rate and high rigidity compared to a metal panel. Therefore, by suppressing the vibration transmission of the speaker 50, an unpleasant sound can be suppressed and an acoustic effect with good response can be obtained.

尚、本発明は上記実施形態に限定されない。   The present invention is not limited to the above embodiment.

例えば、上記実施形態では、開口部22の外縁部24における締結部60A(締結孔62A)及び締結部60B(締結孔62B)の周囲に補強リブ70A、72A及び補強リブ70B、72Bを設けたが、これに限定されない。外縁部24における締結部60C(締結孔62C)及び締結部60D(締結孔62D)の周囲に補強リブを設けてもよい。つまり、外縁部24における締結部60A、60B、60C、60D(締結孔62A、62B、62C、62D)の隣り合う少なくとも二以上の周囲に補強リブを設ければよい。   For example, in the above embodiment, the reinforcing ribs 70A and 72A and the reinforcing ribs 70B and 72B are provided around the fastening portion 60A (fastening hole 62A) and the fastening portion 60B (fastening hole 62B) in the outer edge portion 24 of the opening 22. However, the present invention is not limited to this. Reinforcing ribs may be provided around the fastening portion 60C (fastening hole 62C) and the fastening portion 60D (fastening hole 62D) in the outer edge portion 24. That is, reinforcing ribs may be provided around at least two or more adjacent fastening portions 60A, 60B, 60C, and 60D (fastening holes 62A, 62B, 62C, and 62D) in the outer edge portion 24.

なお、連結リブは、補強リブが設けられた隣り合う締結部(締結孔)を結ぶ仮想線の外側で隣り合う補強リブ同士を連結するように設ければよい。例えば、上記実施形態で、仮に外縁部24における締結部60C(締結孔62C)及び締結部60D(締結孔62D)の周囲に補強リブが設けられている場合、下側リブ82及び上側リブ84が、それぞれ隣り合う補強リブ同士を連結するように設ければよい。また、外縁部24に開口部22を取囲むようにリング状に繋がった連結リブを設けてもよい。   In addition, what is necessary is just to provide a connection rib so that adjacent reinforcement ribs may be connected on the outer side of the virtual line which connects the adjacent fastening part (fastening hole) provided with the reinforcement rib. For example, in the above embodiment, if reinforcing ribs are provided around the fastening portion 60C (fastening hole 62C) and the fastening portion 60D (fastening hole 62D) in the outer edge portion 24, the lower rib 82 and the upper rib 84 are provided.
