上記のように構成されたバックドアストッパ１を、バックドア開口部６０の側部に位置するバックピラーアウタパネル６１の後面６１ａに取り付けた状態で、バックドアを閉じるとき、バックドアの側部は、バックドアストッパ１を押圧する。 When the back door stopper 1 configured as described above is mounted on the rear surface 61a of the back pillar outer panel 61 located on the side of the back door opening 60, when the back door is closed, the side of the back door is The back door stopper 1 is pressed.
詳細には、バックドアの側部は、バックドアストッパ１の特に複数の段差形状部を有する部分（車幅方向内側部）を、押圧する。このとき、バックドアストッパ１には、車両前後方向及び車幅方向の荷重が作用する。バックドアストッパ１は、車両前後方向の荷重が作用すると、第１縦壁部１８、第２縦壁部２８、第３縦壁部３８及び第４縦壁部４８が、車両前方または車両後方に湾曲して撓む。このため、第１〜第５の貫通孔１６〜５６を設けない場合に比べて、すなわち、第１縦壁部１８、第２縦壁部２８、第３縦壁部３８及び第４縦壁部４８を有しない場合に比べて、車両前後方向のばね定数は低くなる。本実施形態では、ストッパ本体１ａのばね定数に最も寄与する部分は、外壁面部４となる。 More specifically, the side portion of the back door presses a portion of the back door stopper 1 particularly having a plurality of step-shaped portions (the inside portion in the vehicle width direction). At this time, a load acts on the back door stopper 1 in the vehicle front-rear direction and the vehicle width direction. When a load in the vehicle front-rear direction acts, the back door stopper 1 moves the first vertical wall portion 18, the second vertical wall portion 28, the third vertical wall portion 38, and the fourth vertical wall portion 48 forward or rearward of the vehicle. It bends and flexes. For this reason, compared with the case where the first to fifth through holes 16 to 56 are not provided, that is, the first vertical wall portion 18, the second vertical wall portion 28, the third vertical wall portion 38, and the fourth vertical wall portion are provided. The spring constant in the front-rear direction of the vehicle is lower than that in the case where no 48 is provided. In the present embodiment, the portion of the stopper main body 1a that most contributes to the spring constant is the outer wall surface portion 4.
一方、バックドアストッパ１に車幅方向の荷重が作用して、車幅方向に変形しようとするとき、当該変形を阻害する力（抗力）は、第１縦壁部１８、第２縦壁部２８、第３縦壁部３８及び第４縦壁部４８によってもたらされる。すなわち、これらの第１縦壁部１８等が、いわゆる、つっかえ棒として機能する。さらに、前壁面部２と第５後面部５２も、車幅方向の変形を阻害する力をもたらす。そのため、ストッパ本体１ａの車幅方向のばね定数は、車両前後方向のばね定数に対して、大きく設定される。 On the other hand, when a load in the vehicle width direction acts on the back door stopper 1 and attempts to deform in the vehicle width direction, the force (drag) inhibiting the deformation is the first vertical wall portion 18 and the second vertical wall portion. 28, the third vertical wall portion 38 and the fourth vertical wall portion 48. That is, these first vertical wall portions 18 and the like function as a so-called packing rod. Furthermore, the front wall portion 2 and the fifth rear surface portion 52 also provide a force that inhibits deformation in the vehicle width direction. Therefore, the spring constant of the stopper body 1a in the vehicle width direction is set to be larger than the spring constant in the vehicle front-rear direction.
このようにバックドアストッパ１を構成することにより、車両前後方向のばね定数を低くして車両前後方向の振動によるこもり音を抑制し、車幅方向のばね定数を高くしてバックドアの横揺れを抑制することが可能となる。 By configuring the back door stopper 1 in this manner, the spring constant in the vehicle front-rear direction is reduced to suppress muffled sound due to vibration in the vehicle front-rear direction, and the spring constant in the vehicle width direction is increased to cause the back door to roll. Can be suppressed.
また、第１〜第５の段差形状部１１〜５５に傾斜部を設けているので、当該傾斜部でバックドアの側部を受けることができる。第１〜第５の段差形状部１１〜５５の角部でバックドアの側部を受ける場合に比べて、荷重が分散されやすくなる。その結果、バックドアストッパ１に作用する負荷が分散され、バックドアストッパ１の損耗を抑制できる。 Further, since the first to fifth step-shaped portions 11 to 55 are provided with the inclined portions, the side portions of the back door can be received by the inclined portions. The load is more easily dispersed than in the case where the side portions of the back door are received at the corners of the first to fifth step-shaped portions 11 to 55. As a result, the load acting on the back door stopper 1 is dispersed, and wear of the back door stopper 1 can be suppressed.
［第２の実施形態］
続いて、本発明に係る第２の実施形態について、図５を参照しながら説明する。本実施形態は、第１の実施形態（図１〜図４）の変形例であって、第１の実施形態と同一部分または類似部分には、同一符号を付して、重複説明を省略する。
[Second embodiment]
Subsequently, a second embodiment according to the present invention will be described with reference to FIG. This embodiment is a modification of the first embodiment (FIGS. 1 to 4), and the same or similar portions as those in the first embodiment are denoted by the same reference numerals, and redundant description is omitted. .
本実施形態では、図５に示すように、車両前後方向に並んで配置される第１の貫通孔１６と第２の貫通孔２６との間を連通する第１連通部１９が設けられている。第１連通部１９は、第１の実施形態で説明した第１縦壁部１８に相当する部分が、空間になっている。 In the present embodiment, as shown in FIG. 5, a first communication portion 19 that communicates between the first through-hole 16 and the second through-hole 26 arranged side by side in the vehicle front-rear direction is provided. . In the first communication portion 19, a portion corresponding to the first vertical wall portion 18 described in the first embodiment is a space.
また、第２の貫通孔２６と第３の貫通孔３６との間には、第２連通部２９が設けられている。同様に、第３の貫通孔３６と第４の貫通孔４６との間には、第３連通部３９が設けられ、第４の貫通孔４６と第５の貫通孔５６との間には、第４連通部４９が設けられている。 In addition, a second communication portion 29 is provided between the second through hole 26 and the third through hole 36. Similarly, a third communication portion 39 is provided between the third through-hole 36 and the fourth through-hole 46, and between the fourth through-hole 46 and the fifth through-hole 56, A fourth communication portion 49 is provided.
本実施形態では、第１連通部１９は、第１の貫通孔１６の車幅方向内側部と第２の貫通孔２６の車幅方向外側部とを連通している。第２連通部２９は、第２の貫通孔２６の車幅方向内側部と第３の貫通孔３６の車幅方向外側部とを連通している。第３連通部３９は、第３の貫通孔３６の車幅方向内側部と第４の貫通孔４６の車幅方向外側部とを連通している。また、第４連通部４９は、第４の貫通孔４６の車幅方向内側部と第５の貫通孔５６の車幅方向外側部とを連通している。 In the present embodiment, the first communication portion 19 communicates the inside portion of the first through hole 16 in the vehicle width direction and the outside portion of the second through hole 26 in the vehicle width direction. The second communication portion 29 communicates the inside of the second through hole 26 in the vehicle width direction and the outside of the third through hole 36 in the vehicle width direction. The third communication portion 39 communicates the inside of the third through hole 36 in the vehicle width direction and the outside of the fourth through hole 46 in the vehicle width direction. Further, the fourth communication portion 49 communicates the inside of the fourth through hole 46 in the vehicle width direction and the outside of the fifth through hole 56 in the vehicle width direction.
上記のように構成されたバックドアストッパ１を、バックドア開口部６０の側部に位置するバックピラーアウタパネル６１の後面６１ａに取り付けた状態で、バックドアを閉じるとき、バックドアの側部は、バックドアストッパ１を押圧する。このとき、バックドアストッパ１には、第１の実施形態と同様に、車両前後方向及び車幅方向の荷重が作用する。 When the back door stopper 1 configured as described above is mounted on the rear surface 61a of the back pillar outer panel 61 located on the side of the back door opening 60, when the back door is closed, the side of the back door is The back door stopper 1 is pressed. At this time, a load in the vehicle front-rear direction and the vehicle width direction acts on the back door stopper 1 as in the first embodiment.
バックドアストッパ１は、車両前後方向の荷重が作用すると、第１側面部１３等が車幅方向外側に変形し、第１側面部１３の内側は、外側壁部の車幅方向内側を押圧する。このとき、第１側面部１３は、第１連通部１９の領域では容易に変形し、その後、外側壁部の車幅方向外側で抗力を受ける。第２側面部２３、第３側面部３３、第４側面部４３及び第５側面部５３は、第１側面部１３と同様に変形する。 When a load in the vehicle front-rear direction acts on the back door stopper 1, the first side surface portion 13 and the like are deformed outward in the vehicle width direction, and the inside of the first side surface portion 13 presses the inside of the outer wall portion in the vehicle width direction. . At this time, the first side surface portion 13 is easily deformed in the region of the first communication portion 19, and thereafter receives a drag outside the outer wall portion in the vehicle width direction. The second side surface portion 23, the third side surface portion 33, the fourth side surface portion 43, and the fifth side surface portion 53 are deformed similarly to the first side surface portion 13.
第１の実施形態に比べて、第１連通部１９の車幅方向幅寸法の分だけ車幅方向に容易に変形可能になる。すなわち、第１連通部１９等を設けることにより、車幅方向のばね定数を調整することが可能となる。 Compared to the first embodiment, the first communication portion 19 can be easily deformed in the vehicle width direction by the width dimension in the vehicle width direction. That is, by providing the first communication portion 19 and the like, the spring constant in the vehicle width direction can be adjusted.
本実施形態では、車両前後方向に並んで配置されている貫通孔の間の全てに、連通部が設けられているがこれに限らない。車幅方向のばね定数を調整するために、車両前後方向のほぼ中央に位置する第３連通部３９のみを設けてもよい。 In the present embodiment, the communication portion is provided between all the through holes arranged in the vehicle front-rear direction, but is not limited to this. In order to adjust the spring constant in the vehicle width direction, only the third communication portion 39 located substantially at the center in the vehicle front-rear direction may be provided.
第２の貫通孔２６の車両前後方向長さ（図３の車両前後方向寸法ｂ）は、第１連通部１９の車幅方向長さ（図３の車幅方向寸法ａ）よりも長い。このよう、車幅方向寸法ａを車両前後方向寸法ｂよりも短くすることで、第１側面部１３が車幅方向に変形しやすい領域（第１連通部１９）よりも、第２後面部２２が車両前方に変形しやすい領域（第２の貫通孔２６）の方が大きくなる。その結果、ストッパ本体１ａの車幅方向のばね定数は、車両前後方向のばね定数に対して、大きく設定される。 The length of the second through hole 26 in the vehicle longitudinal direction (the vehicle longitudinal direction dimension b in FIG. 3) is longer than the length of the first communication portion 19 in the vehicle width direction (the vehicle width direction dimension a in FIG. 3). In this manner, by making the vehicle width direction dimension a shorter than the vehicle front-rear direction dimension b, the second rear surface portion 22 can be larger than the region (the first communication portion 19) where the first side surface portion 13 is easily deformed in the vehicle width direction. Is larger in a region (the second through hole 26) in which the vehicle is easily deformed in front of the vehicle. As a result, the spring constant of the stopper body 1a in the vehicle width direction is set to be larger than the spring constant in the vehicle front-rear direction.
