A rocker inner panel that extends in the vehicle longitudinal direction inside the rocker outer panel in the vehicle width direction and has a cross-sectional hat shape that opens outward in the vehicle width direction and forms a closed cross-sectional structure with the rocker outer panel, and the rocker A rocker inner hose disposed between the inner panel and the rocker outer panel, extending in the vehicle front-rear direction, and having a cross-sectional hat shape opening inward in the vehicle width direction and forming a closed cross-sectional structure with the rocker inner panel When the disposed rocker inner panel and the rocker official cross-section of the closed cross section formed by a hose, to the rocker reinforcements Ne The combined and having a reinforcing member joined in a state in which a gap, and with the inner opening is formed through the reinforcing member, the rocker reinforcements are provided superposed with the inner opening And an outer opening having an upper end position that is offset to the upper side of the vehicle body with respect to the inner opening is formed to penetrate therethrough .

請求項１に記載の車体のロッカ構造では、ロッカインナパネルとロッカアウタパネルとで閉断面構造が形成されると共に、ロッカインナパネルとロッカアウタパネルとの間に配設されたロッカリインホースと、ロッカインナパネルとで閉断面構造が形成されている。また、ロッカインナパネルとロッカリインホースとで形成された閉断面構造の断面内に補強部材が配設され、この補強部材は、ロッカリインホースに重ね合わされた状態で接合されている。 In the rocker structure of the vehicle body according to claim 1 , a closed section structure is formed by the rocker inner panel and the rocker outer panel, and a rocker inner hose disposed between the rocker inner panel and the rocker outer panel, and a rocker inner A closed cross-sectional structure is formed with the panel. In addition, a reinforcing member is disposed in the cross section of the closed cross-sectional structure formed by the rocker inner panel and the rocker inner hose, and the reinforcing member is joined in a state of being superimposed on the rocker inner hose .

ロッカアウタパネルの下部には貫通穴が形成され、補強部材には内側開口部が貫通形成されると共に、ロッカリインホースには外側開口部が貫通形成されて内側開口部に重ね合わせて設けられており、車体のロッカを防錆処理液に浸漬した際に、車体のロッカの断面内へ防錆処理液を流し込むことが可能となっている。また、補強部材がロッカリインホースに隙間を空けた状態で接合されていることにより、車体のロッカを防錆処理液に浸漬した際に、補強部材とロッカリインホースとの隙間に防錆処理液を流し込むことが可能となっている。 A through hole is formed in the lower part of the rocker outer panel, an inner opening is formed in the reinforcing member, and an outer opening is formed in the rocker inhose so as to overlap the inner opening. When the rocker of the vehicle body is immersed in the antirust treatment liquid, the antirust treatment liquid can be poured into the cross section of the rocker of the vehicle body. Further, since the reinforcing member is joined in a state where a gap in the rocker reinforcements, upon immersing the body of the rocker to the rustproofing liquid, antirust treatment liquid in the gap between the reinforcing member and the rocker reinforcements Can be poured.

ここで、外側開口部の上端位置が、内側開口部に対して車体上側にオフセットして配置されており、補強部材の内側開口部より車体上側の部位が外側開口部と重なり合っている。このため、車体のロッカを防錆処理液に浸漬した際に、防錆処理液が、補強部材の内側開口部より車体上側の部位に当たり、該部位を伝って該部位の車体上方の上記隙間へ流れ込む。 Here, the upper end position of the outer opening is arranged offset to the upper side of the vehicle body with respect to the inner opening, and a portion of the reinforcing member on the upper side of the vehicle body overlaps the outer opening. For this reason, when the rocker of the vehicle body is immersed in the anti-corrosion treatment liquid, the anti-corrosion treatment liquid hits the site on the upper side of the vehicle body from the inner opening of the reinforcing member and travels through the site to the gap above the vehicle body of the site. Flows in.

即ち、補強部材の内側開口部より車体上側、且つ外側開口部と重なり合う部位により、該部位の車体上方の上記隙間へ防錆処理液が積極的に流し込まれる。よって、内側開口部及び外側開口部の車体上側において、ロッカリインホースの補強部材との対向面、及び補強部材のロッカリインホースとの対向面への防錆処理液の付着が促進される。 That is, the rust preventive liquid is actively poured into the gap above the vehicle body at the upper part of the vehicle body from the inner opening of the reinforcing member and the outer opening. Therefore, in the vehicle body upper side of the inner opening and the outer opening, the opposing surfaces of the reinforcing member of the rocker reinforcements, and adhesion of rustproofing liquid to the surface facing the rocker reinforcements of the reinforcing member is facilitated.

請求項２に記載の車体のロッカ構造は、請求項１に記載の車体のロッカ構造であって、前記外側開口部の車体上下方向中央部は、前記内側開口部の車体上下方向中央部に対して車体上側にオフセットして配置されていることを特徴とする。 Rocker structure of the vehicle body according to claim 2 is the vehicle body rocker structure according to claim 1, the vehicle body vertical direction central portion of the outer opening, with respect to the vehicle vertical direction central portion of the inner opening It is characterized by being offset from the upper side of the vehicle body.

請求項２に記載の車体のロッカ構造では、外側開口部の車体上下方向中央部が、内側開口部の車体上下方向中央部に対して車体上側にオフセットして配置されている。これにより、外側開口部を拡大させることなく、また、内側開口部を縮小させることなく、補強部材の内側開口部より車体上側であり、外側開口部と重なり合う部位の面積を拡大させることができる。 In the rocker structure of the vehicle body according to the second aspect, the vehicle body vertical direction center portion of the outer opening portion is disposed offset to the vehicle body upper side with respect to the vehicle body vertical direction center portion of the inner opening portion. Accordingly, the area of the portion that is on the upper side of the vehicle body from the inner opening of the reinforcing member and overlaps the outer opening can be increased without enlarging the outer opening and without reducing the inner opening.

よって、ロッカリインホースの強度の低下を抑制し、且つ、車体のロッカの断面内への防錆処理液の流入に対する影響を抑制しつつ、内側開口部及び外側開口部の車体上側において、ロッカリインホースの補強部材との対向面及び補強部材のロッカリインホースとの対向面への防錆処理液の付着を促進させることが可能である。 Therefore, suppressing a decrease in the strength of the rocker reinforcements, and, while suppressing the influence on the flow of rustproofing liquid to the body of the rocker in cross-section, in a vehicle body upper side of the inner opening and the outer opening, Rokkariin it is possible to accelerate the rustproofing liquid adhering to the surface facing the rocker reinforcements facing surfaces and the reinforcing member and the reinforcing member of the hose.

However, it is thicker than the thickness of the rocker outer panel 24 and the rocker inner panel 28.

次に、本実施形態における作用について説明する。   Next, the operation in this embodiment will be described.

車体１２の塗装前に実施される防錆処理工程では、車体１２を防錆処理液（ＥＤ液）の入った浴槽に浸漬し、車体１２の全体に防錆処理液を付着させる。ここでは、ロッカ２６の防錆処理について説明する。   In the rust prevention process performed before the vehicle body 12 is painted, the vehicle body 12 is immersed in a bathtub containing an rust prevention liquid (ED liquid), and the rust prevention liquid is attached to the entire vehicle body 12. Here, the antirust treatment of the rocker 26 will be described.

図５に示すように、ロッカ２６では、図中矢印Ａで示すように、防錆処理液が、ロッカアウタパネル２４の下部に形成されたＥＤ穴３４から、ロッカアウタパネル２４とロッカリインホース３０との間の閉断面内へ流れ込み、ロッカアウタパネル２４の内壁、及びロッカリインホース３０の外壁に付着する。   As shown in FIG. 5, in the rocker 26, as indicated by an arrow A in the figure, the rust preventive liquid is passed through the ED hole 34 formed in the lower part of the rocker outer panel 24 to form the rocker outer panel 24 and the rocker in hose 30. It flows into the closed cross section between them and adheres to the inner wall of the rocker outer panel 24 and the outer wall of the rocker-in hose 30.

また、ロッカアウタパネル２４とロッカリインホース３０との間の閉断面内へ流れ込んだ防錆処理液は、ロッカリインホース３０に形成されたＥＤ穴３６、及びＬ字リインホース３２に形成されたＥＤ穴３８から閉断面構造体１０の閉断面内へ流れ込み、閉断面構造体１０の内壁に付着する。 Further, the rust preventive liquid that has flowed into the closed cross section between the rocker outer panel 24 and the rocker-in hose 30 is the ED hole 36 formed in the rocker-in hose 30 and the ED hole 38 formed in the L-shaped reinhose 32. Flows into the closed section of the closed section structure 10 and adheres to the inner wall of the closed section structure 10.

また、ロッカアウタパネル２４とロッカリインホース３０との間の閉断面内へ流れ込んだ防錆処理液の一部は、ＥＤ穴３６、３８の下側の隙間Ｏへ流れ込み、縦壁部３０Ａ、３２Ａの下部（ＥＤ穴３６、３８の下側）の互いに対向する面に付着する。   Further, a part of the antirust treatment liquid that has flowed into the closed cross section between the rocker outer panel 24 and the rocker-in-hose 30 flows into the gap O below the ED holes 36 and 38, and the vertical wall portions 30A and 32A. It adheres to the mutually opposing surfaces of the lower part (under the ED holes 36 and 38).

また、閉断面構造体１０の閉断面内に流れ込んだ防錆処理液の一部は、ロッカリインホース３０の下壁部３０Ｃの内壁を伝ってＥＤ穴３６、３８の下側の隙間Ｏへ流れ込み、縦壁部３０Ａ、３２Ａの下部（ＥＤ穴３６、３８の下側）の互いに対向する面に付着する。   Further, a part of the antirust treatment liquid that has flowed into the closed cross section of the closed cross section structure 10 flows into the gap O below the ED holes 36 and 38 along the inner wall of the lower wall portion 30C of the rocker inhose 30. Adhering to the mutually opposing surfaces of the lower portions of the vertical wall portions 30A, 32A (under the ED holes 36, 38).

ここで、ＥＤ穴３６の上端位置３６Ｈが、ＥＤ穴３８の上端位置３８Ｈに対して車体上側にオフセットして配置されており、縦壁部３２Ａの上部（ＥＤ穴３８の上側）が、ＥＤ穴３６と重合する高さから車体上方へ延在している。このため、防錆処理液が、縦壁部３２ＡのＥＤ穴３６と重合する重合部３２Ｄ（図４に斜線で図示）に当たり、該重合部３２Ｄを伝ってＥＤ穴３６、３８の上側の隙間Ｏへ流れ込み、縦壁部３０Ａ、３２Ａの上部（ＥＤ穴３６、３８の上側）の互いに対向する面に付着する。   Here, the upper end position 36H of the ED hole 36 is disposed offset to the upper side of the vehicle body with respect to the upper end position 38H of the ED hole 38, and the upper portion of the vertical wall portion 32A (the upper side of the ED hole 38) is the ED hole. 36 extends upward from the height where it overlaps with 36. For this reason, the anticorrosive treatment liquid hits the overlapping portion 32D (shown by hatching in FIG. 4) where it overlaps with the ED hole 36 of the vertical wall portion 32A, passes through the overlapping portion 32D, and the gap O above the ED holes 36, 38. To the upper surfaces of the vertical wall portions 30A and 32A (upper sides of the ED holes 36 and 38).

即ち、重合部３２Ｄにより、防錆処理液がＥＤ穴３６、３８の上側の隙間Ｏへ積極的に流し込まれる。よって、ＥＤ穴３６、３８の車体上側において、ロッカリインホース３０とＬ字リインホース３２との隙間Ｏを介して互いに対向する面への防錆処理液の付着（つきまわり）が促進される。   In other words, the rust preventive liquid is actively poured into the gap O above the ED holes 36 and 38 by the overlapping portion 32D. Therefore, the adhesion (around) of the rust preventive liquid to the surfaces facing each other through the gap O between the rocker-in hose 30 and the L-shaped rein hose 32 is promoted on the upper side of the vehicle body of the ED holes 36 and 38.

また、ここで、図２及び図４に示すように、ＥＤ穴３６の中心（上下方向中央部）を、ＥＤ穴３８の中心（上下方向中央部）に対して車体上側にオフセットして配置したことにより、ＥＤ穴３６の直径を拡大させることなく、また、ＥＤ穴３８の直径を縮小させることなく、上記重合部３２Ｄの面積を拡大させることができる。よって、強度部材であるロッカリインホース３０の強度の低下を抑制しつつ、また、閉断面構造体１０の断面内への防錆処理液の流入に対する影響を抑制しつつ、ＥＤ穴３６、３８の車体上側において、ロッカリインホース３０とＬ字リインホース３２との隙間Ｏを介して互いに対向する面への防錆処理液の付着を促進することが可能である。   Here, as shown in FIGS. 2 and 4, the center of the ED hole 36 (vertical center) is offset from the center of the ED hole 38 (vertical center) on the upper side of the vehicle body. Thus, the area of the overlapping portion 32D can be increased without increasing the diameter of the ED hole 36 and without reducing the diameter of the ED hole 38. Therefore, while suppressing a decrease in strength of the rocker-in hose 30 which is a strength member, and suppressing an influence on the inflow of the rust preventive liquid into the cross section of the closed cross-section structure 10, On the upper side of the vehicle body, it is possible to promote the adhesion of the anticorrosive treatment liquid to the surfaces facing each other through the gap O between the rocker-in hose 30 and the L-shaped rein hose 32.

なお、本実施形態では、ＥＤ穴３６の下端位置３６ＬとＥＤ穴３８の下端位置３８Ｌとを、略同一の高さに配置することにより、上記重合部３２Ｄの面積を最大限まで拡大させたが、図６に示すように、ＥＤ穴３６の中心をＥＤ穴３８の中心に対して車体上側にオフセットして配置するのみで、ＥＤ穴３６の下端位置３６ＬをＥＤ穴３８の下端位置３８Ｌの車体下側に配置してもよい。   In the present embodiment, the area of the overlapping portion 32D is expanded to the maximum by arranging the lower end position 36L of the ED hole 36 and the lower end position 38L of the ED hole 38 at substantially the same height. As shown in FIG. 6, the lower end position 36L of the ED hole 36 is set to the lower end position 38L of the ED hole 38 only by offsetting the center of the ED hole 36 to the upper side of the vehicle body with respect to the center of the ED hole 38. It may be arranged on the lower side.
