Description

本発明は車輌の車体後部構造に関し、特に、車輌の後突時に、車体後部に収納されるジャッキが客室に飛散することを防止する技術に関する。   The present invention relates to a vehicle body rear portion structure of a vehicle, and more particularly to a technique for preventing a jack housed in a vehicle body rear portion from being scattered in a passenger compartment at the time of a rear collision of the vehicle.

一般に車輌にはタイヤを交換する際等に用いられるジャッキが搭載されている。通常、ジャッキは車体後部のフロアパネル上に搭載エリアが設けられ、ここに搭載されることになる。一方、車体後部のフロアパネル上はスペアタイヤの収納空間として用いられることが多く、ジャッキの搭載箇所はスペアタイヤの収納を考慮して設定する必要がある。車体後部のフロアパネル上におけるジャッキの搭載箇所としてはスペアタイヤの前方、後方、側方、或いは、リアホイールハウス後方のスペースが挙げられる。ここで、車体後部のフロアパネル上は一般に前後長よりも幅が大きくとられる。従って、スペアタイヤの前方、後方にジャッキを搭載する場合、搭載箇所のスペースが確保しづらいという問題がある。ジャッキをスペアタイヤの前方に搭載した場合には更にジャッキの取り出しに手間がかかるという問題もあり、ほとんど採用されていない。   Generally, a vehicle is equipped with a jack that is used when changing tires. Normally, a jack is provided with a mounting area on a floor panel at the rear of the vehicle body, and is mounted here. On the other hand, the floor panel at the rear of the vehicle body is often used as a spare tire storage space, and the jack mounting location must be set in consideration of the spare tire storage. Examples of the jack mounting location on the floor panel at the rear of the vehicle body include the space at the front, rear, side, or rear of the rear wheel house. Here, the width of the floor panel at the rear of the vehicle body is generally larger than the longitudinal length. Therefore, when a jack is mounted in front of or behind the spare tire, there is a problem that it is difficult to secure a space for the mounting position. When the jack is mounted in front of the spare tire, there is a problem that it takes time to take out the jack, and it is hardly adopted.

また、リアホイールハウス後方のスペースは上下方向には余裕があるものの前後左右のスペースは小さい。従って、ジャッキを倒立状態にて搭載することが必要となる。しかし、フロアパネル上方にトランクルーム等を形成する場合、トランクルームの車幅方向の端部をジャッキの上端部の収納スペースとする必要があり、ゴルフバック等の長物を収納するスペースが十分に確保することができなくなる。そこで、レイアウトを考慮した場合、特許文献１に記載されるように、ジャッキの長手方向を車体の前後方向として、スペアタイヤの側方に搭載する方式が望ましい。   In addition, the space behind the rear wheel house has room in the vertical direction, but the space in the front, rear, left and right is small. Therefore, it is necessary to mount the jack in an inverted state. However, when a trunk room or the like is formed above the floor panel, the end of the trunk room in the vehicle width direction needs to be a storage space for the upper end of the jack, and a sufficient space for storing a long item such as a golf bag must be secured. Can not be. In view of the layout, as described in Patent Document 1, it is desirable that the jack be mounted on the side of the spare tire with the longitudinal direction of the jack as the longitudinal direction of the vehicle body.

特開２００１−２５３３０３号公報JP 2001-253303 A

ここで、車輌の後突時には車体後部が変形し、後突の衝撃で車体後部に搭載された搭載物が客室内へ飛散する場合がある。車体後部にジャッキを搭載した場合にはジャッキが客室内へ飛散する場合がある。特に、ジャッキをスペアタイヤの側方に搭載する方式を採用した場合、スペアタイヤの後方やリアホイールハウス後方のスペースに搭載する場合に比べて、車体前方へのジャッキの飛散の妨げとなるものが少なく、ジャッキが客室内へ飛散し易い傾向にある。これを解決するためにジャッキを強固に固定しておく方法が考えられるが、この場合、ジャッキの取り外しに手間がかかり、ジャッキの出し入れの作業性が劣る。   Here, the rear part of the vehicle body may be deformed at the time of a rear collision of the vehicle, and a load mounted on the rear part of the vehicle body may be scattered into the passenger compartment due to the impact of the rear collision. When a jack is mounted on the rear part of the vehicle body, the jack may be scattered into the cabin. In particular, when a method of mounting a jack on the side of a spare tire is adopted, there are things that prevent the jack from scattering forward of the vehicle body compared to the case of mounting in the space behind the spare tire or the rear wheel house. There are few, and there is a tendency for jacks to be easily scattered in the cabin. In order to solve this, a method of fixing the jack firmly is conceivable. However, in this case, it takes time to remove the jack, and the workability of taking in and out the jack is inferior.

従って、本発明の目的は、ジャッキの出し入れの作業性を確保しつつ、車輌の後突時に車体後部に搭載されたジャッキが客室内へ飛散することを防止できる車体後部構造を提供することにある。   Accordingly, an object of the present invention is to provide a vehicle body rear part structure that can prevent the jack mounted on the rear part of the vehicle body from splashing into the passenger compartment at the time of rear collision of the vehicle while ensuring the workability of inserting and removing the jack. .

第１の本発明によれば、ジャッキをその長手方向が車体前後方向を向くように車体後部のフロアパネル上に支持するジャッキ支持部と、スペアタイヤを前記フロアパネル上で支持するタイヤ支持部と、を備えた車体後部構造において、前記ジャッキ支持部は、前記タイヤ支持部に支持された前記スペアタイヤと、車体の側壁との間において前記ジャッキを支持するように配設され、前記タイヤ支持部に支持された前記スペアタイヤと前記側壁との間において、前記ジャッキ支持部から車体前方に離間して前記フロアパネル上に配設され、後突時に前記ジャッキが車体前方上側へ移動することを規制する規制部材を備え、前記規制部材は、前記ジャッキ支持部によって、その長手方向が車体前後方向を向くように支持された状態の前記ジャッキの前端部を該前端部から離間して上から覆う部分を有することを特徴とする車体後部構造が提供される。
また、第２の本発明によれば、ジャッキをその長手方向が車体前後方向を向くように車体後部のフロアパネル上に支持するジャッキ支持部を備えた車体後部構造において、前記ジャッキ支持部よりも車体前方において前記フロアパネル上に配設され、後突時に前記ジャッキが車体前方上側へ移動することを規制する規制部材と、前記ジャッキ支持部よりも車体前方において前記フロアパネル上に配設され、車幅方向に延在するクロスメンバと、を備え、前記規制部材は、前記クロスメンバから車体後方へ向けて配設されており、前記クロスメンバは、後突時に前記ジャッキが車体前方へ移動することを規制する高さを有すると共に前記ジャッキの前端と対面する対面部分を有する縦壁部を備え、前記規制部材は、後突時に車体前方に移動する前記ジャッキの前端部を前記対面部分に案内する形状を有することを特徴とする車体後部構造が提供される。 According to the first aspect of the present invention, the jack support portion that supports the jack on the floor panel at the rear of the vehicle body so that the longitudinal direction thereof faces the vehicle longitudinal direction, and the tire support portion that supports the spare tire on the floor panel. The jack support portion is disposed so as to support the jack between the spare tire supported by the tire support portion and a side wall of the vehicle body, and the tire support portion. Between the spare tire supported on the side wall and the side wall, the jack is disposed on the floor panel so as to be separated from the jack support portion in front of the vehicle body, and the jack is restricted from moving forward in the vehicle body at the time of a rear collision. comprising a restricting member for said regulating member, by the jack support portion, said jack in a state where its longitudinal direction is supported so as to face the longitudinal direction of the vehicle body Rear body structure and having a portion covering from above apart the front end from the front end portion is provided.
Further, according to the second aspect of the present invention, in the vehicle body rear portion structure including the jack support portion that supports the jack on the floor panel of the rear portion of the vehicle body so that the longitudinal direction thereof faces the vehicle longitudinal direction, the jack support portion is more than the jack support portion. A restricting member that is disposed on the floor panel in front of the vehicle body and restricts the jack from moving to the upper front side of the vehicle body at the time of a rear collision; and disposed on the floor panel in front of the vehicle body than the jack support portion; A cross member extending in the vehicle width direction, and the restricting member is disposed from the cross member toward the rear of the vehicle body, and the jack moves forward of the vehicle body at the time of a rear collision. A vertical wall portion having a height that restricts this and having a facing portion facing the front end of the jack, and the restricting member moves forward of the vehicle body at the time of a rear collision Rear body structure characterized in that it has a shape for guiding the front end of the serial jack to the facing portion is provided.

第１及び第２の本発明によれば、ジャッキの出し入れの作業性を確保しつつ、車輌の後突時に車体後部に搭載されたジャッキが客室内へ飛散することを防止することができる。また、第１の本発明によれば、ジャッキが車体前方上側へ移動することがより確実に規制され、ジャッキが客室内へ飛散することをより効果的に防止することができる。また、第２の本発明によれば、規制部材の案内によりジャッキが縦壁部に衝突し、縦壁部が抑止壁となってジャッキの客室内への飛散がより効果的に防止される。また、クロスメンバによりジャッキの車体前後方向の衝撃荷重が負担されるので、規制部材の車体前後方向の剛性を低くすることができ、その小型・軽量化を図ることができる。 According to the first and second aspects of the present invention, it is possible to prevent the jack mounted on the rear part of the vehicle body from scattering into the passenger compartment at the time of the rear collision of the vehicle while ensuring the workability of inserting and removing the jack. In addition, according to the first aspect of the present invention, it is more reliably restricted that the jack moves to the front upper side of the vehicle body, and the jack can be more effectively prevented from scattering into the passenger compartment. Further, according to the second aspect of the present invention, the jack collides with the vertical wall portion by the guide of the restricting member, and the vertical wall portion serves as a deterrent wall, thereby preventing the jack from scattering into the cabin more effectively. Further, since the impact load in the longitudinal direction of the vehicle body of the jack is borne by the cross member, the rigidity of the regulating member in the longitudinal direction of the vehicle body can be reduced, and the size and weight can be reduced.

図１は本発明の一実施形態に係る車体後部構造を採用した自動車Ａの車体後部の荷室空間周辺の構造を示す図である。荷室空間は車体後部のフロアパネル１０上に形成され、破線で示すボード１が間仕切り床となって、上部の荷室空間と下部の荷室空間とに仕切られる。下部の荷室空間にはスペアタイヤＴとジャッキＪとがそれぞれ収納されている。スペアタイヤＴはフロアパネル１０上に設けられたタイヤ支持部１１によりフロアパネル１０上で支持されている。また、ジャッキＪはフロアパネル１０上に設けられたジャッキ支持部１２により支持されている。ジャッキＪよりも車体前方には、車幅方向に延在するクロスメンバ１３がフロアパネル１０上に配設されている。クロスメンバ１３はその両端部が自動車Ａの側壁２にそれぞれ結合されている。ジャッキ支持部１２よりも車体前方には規制部材１４がフロアパネル１０上に配設されている。本実施形態の場合、ボード１がクロスメンバ１３、規制部材１４、ジャッキＪ並びにスペアタイヤＴを上方から覆うように設けられる。   FIG. 1 is a view showing a structure around a luggage compartment space at the rear of a vehicle body of an automobile A employing a vehicle body rear structure according to an embodiment of the present invention. The cargo space is formed on the floor panel 10 at the rear of the vehicle body, and the board 1 indicated by a broken line serves as a partition floor, and is partitioned into an upper cargo space and a lower cargo space. Spare tires T and jacks J are accommodated in the lower cargo space. The spare tire T is supported on the floor panel 10 by a tire support portion 11 provided on the floor panel 10. Further, the jack J is supported by a jack support portion 12 provided on the floor panel 10. A cross member 13 extending in the vehicle width direction is disposed on the floor panel 10 in front of the jack J. Both ends of the cross member 13 are coupled to the side wall 2 of the automobile A, respectively. A regulating member 14 is disposed on the floor panel 10 in front of the vehicle body with respect to the jack support portion 12. In the case of this embodiment, the board 1 is provided so as to cover the cross member 13, the regulating member 14, the jack J, and the spare tire T from above.

図２及び図３を参照して、自動車Ａの車体後部構造を更に説明する。図２及び図３はフロアパネル１０の周辺構造を示す平面視図であり、図２はスペアタイヤＴ及びジャッキＪを外した状態、図３はスペアタイヤＴ及びジャッキＪを取り付けた状態を示す。   With reference to FIG.2 and FIG.3, the vehicle body rear part structure of the motor vehicle A is further demonstrated. 2 and 3 are plan views showing the peripheral structure of the floor panel 10. FIG. 2 shows a state where the spare tire T and the jack J are removed, and FIG. 3 shows a state where the spare tire T and the jack J are attached.

フロアパネル１０は左右一対のリヤサイドフレーム３の上面に結合されており、左右一対のリヤサイドフレーム３間でリヤサイドフレーム３上に支持されている。フロアパネル１０は一対のリヤサイドフレーム３の間のスペースにおいて、スペアタイヤＴが収納可能な円形の凹部１０ａを有する。なお、フロアパネル１０の車体前後方向後端部には不図示のリヤエンドパネル等が結合されることになる。   The floor panel 10 is coupled to the upper surfaces of the pair of left and right rear side frames 3, and is supported on the rear side frame 3 between the pair of left and right rear side frames 3. The floor panel 10 has a circular recess 10 a in which a spare tire T can be stored in a space between the pair of rear side frames 3. Note that a rear end panel (not shown) or the like is coupled to the rear end of the floor panel 10 in the longitudinal direction of the vehicle body.

凹部１０ａの中心部にはタイヤ支持部１１が設けられている。図４（ｂ）はタイヤ支持部１１の構成を示す斜視図である。タイヤ支持部１１は取付板１１１と取付板１１１上に立設され、上端部１１２ａに雄ネジが刻設された軸１１２と、軸１１２の上端部１１２ａのネジに螺合する雌ネジが刻設された穴１１３ａを有するハンドル１１３と、を備え、取付板１１１によりフロアパネル１０の凹部１０ａ上に固定されている。軸１１２にスペアタイヤＴの中心の穴を差込み、ハンドル１１３の穴１１３ａを軸１１２の上端部１１２ａに螺合させることで、スペアタイヤＴがタイヤ支持部１１に固定・支持されることになる。   A tire support 11 is provided at the center of the recess 10a. FIG. 4B is a perspective view showing the configuration of the tire support portion 11. The tire support portion 11 is erected on the attachment plate 111 and the attachment plate 111, and a shaft 112 having a male screw engraved on the upper end portion 112a, and a female screw that engages with a screw of the upper end portion 112a of the shaft 112 are engraved. And a handle 113 having a hole 113a, which is fixed on the recess 10a of the floor panel 10 by a mounting plate 111. By inserting a hole at the center of the spare tire T into the shaft 112 and screwing the hole 113a of the handle 113 into the upper end portion 112a of the shaft 112, the spare tire T is fixed and supported on the tire support portion 11.

ジャッキ支持部１２はジャッキＪをその長手方向が車体前後方向を向くようにフロアパネル１０上に支持している。図４（ａ）はジャッキ支持部１２の構成を示す斜視図である。ジャッキ支持部１２は取付板１２１を備え、取付板１２１によりフロアパネル１０上に固定されている。取付板１２１はジャッキＪが係止される爪部１２１ａを備える。爪部１２１ａは逆Ｌ字型をしており、取付板１２１の平坦部分との間でコの字形の空隙を形成している。この空隙にジャッキＪの脚部Ｊａ（図２参照）が差し込まれることになり、車体前後方向及び上下方向のジャッキＪの移動が規制される。取付板１２１の平坦部分には上端部に雄ネジが刻設された軸体１２１ｂが立設されている。この軸体１２１ｂは、車体のサイドシルなどを支持する、ジャッキＪの支持部に設けられた取付穴Ｊｂ（図２参照）に挿入される。   The jack support portion 12 supports the jack J on the floor panel 10 so that the longitudinal direction thereof faces the vehicle body longitudinal direction. FIG. 4A is a perspective view showing the configuration of the jack support 12. The jack support 12 includes a mounting plate 121 and is fixed on the floor panel 10 by the mounting plate 121. The mounting plate 121 includes a claw portion 121a to which the jack J is locked. The claw portion 121a has an inverted L shape and forms a U-shaped gap with the flat portion of the mounting plate 121. The leg portion Ja (see FIG. 2) of the jack J is inserted into the gap, and the movement of the jack J in the longitudinal direction and the vertical direction of the vehicle body is restricted. A shaft 121b having a male screw carved at the upper end is erected on the flat portion of the mounting plate 121. The shaft body 121b is inserted into a mounting hole Jb (see FIG. 2) provided in a support portion of the jack J that supports a side sill of the vehicle body.

ジャッキ支持部１２は、更に、軸体１２１ｂの上端部の雄ネジに螺合する雌ねじが刻設された穴を有する筒体１２２と、筒体１２２の半径方向に貫通した穴１２２ａに差し込まれるハンドル１２３と、を備える。しかして、ジャッキＪの脚部Ｊａを爪部１２１ａに係止し、ジャッキＪの取付穴Ｊｂに軸体１２１ｂを挿入した後、筒体１２２を軸体１２１ｂの上端部に螺合する。その際、ハンドル１２３を筒体１２２の穴１２２ａに挿入して筒体１２２を回転させることで簡易に螺合できる。螺合が完了することにより、ジャッキＪは爪部１２１ａと軸体１２１ｂとで係止され、ジャッキＪがジャッキ支持部１２に固定・支持されることになる。なお、後突時にはこのジャッキＪがジャッキ支持部１２から外れて客室内へ飛散する畏れがあるが、後述するように本実施形態ではこの飛散を防止する構造を有するので、ジャッキ支持部１２はジャッキＪを強固に固定するものである必要はなく、図４（ａ）に例示したように簡易なもので足りる。従って、ジャッキＪの出し入れの作業性は従来のものと差がなく、作業性を確保できる。   The jack support portion 12 further includes a cylindrical body 122 having a hole in which a female screw threadedly engaged with a male screw at an upper end portion of the shaft body 121b and a handle inserted into a hole 122a penetrating in the radial direction of the cylindrical body 122. 123. Thus, after the leg portion Ja of the jack J is locked to the claw portion 121a and the shaft body 121b is inserted into the mounting hole Jb of the jack J, the cylindrical body 122 is screwed into the upper end portion of the shaft body 121b. At this time, the handle 123 can be easily screwed by inserting the handle 123 into the hole 122 a of the cylinder 122 and rotating the cylinder 122. When the screwing is completed, the jack J is locked by the claw portion 121a and the shaft body 121b, and the jack J is fixed and supported by the jack support portion 12. In this case, the jack J may come off the jack support portion 12 and scatter into the passenger compartment at the time of a rear collision. However, as will be described later, in the present embodiment, the jack support portion 12 has a structure that prevents this scattering. It is not necessary to firmly fix J, and a simple one is sufficient as illustrated in FIG. Therefore, the workability of inserting and removing the jack J is not different from the conventional one, and the workability can be secured.

ここで、図２に示すようにジャッキ支持部１２は車幅方向の中央よりも車体の側壁２（図２にて不図示）側に配設されている。車体後部はその車幅方向中央部分よりも車体の側壁２側の方が側壁２が存在する分だけ前後方向の剛性が高く、後突時の変形も少ないところ、この構成によれば、ジャッキＪが車体の側壁２側寄りに搭載されるので、車幅方向の中央に搭載した場合よりも、後突時にジャッキＪに入力する衝撃が低減される。従って、ジャッキＪの客室内への飛散をより効果的に防止できる。   Here, as shown in FIG. 2, the jack support portion 12 is disposed on the side wall 2 (not shown in FIG. 2) side of the vehicle body from the center in the vehicle width direction. The rear portion of the vehicle body has higher rigidity in the front-rear direction than the central portion in the vehicle width direction as much as the side wall 2 is present, and there is less deformation at the time of rear collision. Is mounted closer to the side wall 2 of the vehicle body, the impact input to the jack J at the time of a rear collision is reduced than when it is mounted in the center in the vehicle width direction. Accordingly, it is possible to more effectively prevent the jack J from scattering into the passenger compartment.

また、図２に示すように本実施形態ではジャッキ支持部１２がリヤサイドフレーム３上に配設されている。リヤサイドフレーム３は車体の前後方向の剛性を高める部材であり、その周辺の剛性は高く、後突時の変形も少ない。このため、ジャッキ支持部１２がリヤサイドフレーム３上に配設することにより、後突時にジャッキＪに入力する衝撃が低減され、ジャッキＪの客室内への飛散をより効果的に防止できる。   Further, as shown in FIG. 2, in the present embodiment, the jack support portion 12 is disposed on the rear side frame 3. The rear side frame 3 is a member that increases the rigidity in the front-rear direction of the vehicle body. For this reason, the jack support portion 12 is disposed on the rear side frame 3, so that an impact input to the jack J at the time of a rear collision is reduced, and the scattering of the jack J into the cabin can be more effectively prevented.

また、図３に示すように本実施形態ではジャッキ支持部１２はタイヤ支持部１１に支持されたスペアタイヤＴと、車体の側壁２（図３において不図示）との間においてジャッキＪを支持するように配設され、かつ、ジャッキＪの後端がタイヤ支持部１１に支持されたスペアタイヤＴのホイールＷの後端縁（線Ｌ）よりも車体前方に位置するように配設されている。この構成によれば、車輌に後突した障害物がジャッキＪよりもスペアタイヤＴのホイールＷに先当りするので衝撃が分散される。従って、後突時にジャッキＪに入力する衝撃が低減され、ジャッキＪの客室内への飛散をより効果的に防止できる。   Further, as shown in FIG. 3, in the present embodiment, the jack support portion 12 supports the jack J between the spare tire T supported by the tire support portion 11 and the side wall 2 (not shown in FIG. 3) of the vehicle body. And the rear end of the jack J is disposed in front of the vehicle body with respect to the rear end edge (line L) of the wheel W of the spare tire T supported by the tire support 11. . According to this configuration, since the obstacle that has collided with the vehicle hits the wheel W of the spare tire T before the jack J, the impact is dispersed. Therefore, the impact input to the jack J at the time of a rear collision is reduced, and scattering of the jack J into the cabin can be more effectively prevented.

次に、クロスメンバ１３及び規制部材１４の構成について説明する。まず、クロスメンバ１３から説明する。クロスメンバ１３は自動車Ａの車体後部の車幅方向の剛性を補強する補強部材であり、本実施形態ではこれをジャッキ支持部１２よりも車体前方においてフロアパネル１０上に設けることでジャッキＪの客室内への飛散防止を図っている。図５（ａ）はクロスメンバ１３及び規制部材１４の周辺構造を示す斜視図、図５（ｂ）は図５（ａ）の線Ｉ−Ｉに沿う断面図である。   Next, the configuration of the cross member 13 and the regulating member 14 will be described. First, the cross member 13 will be described. The cross member 13 is a reinforcing member that reinforces the rigidity in the vehicle width direction of the rear portion of the vehicle body of the automobile A. In the present embodiment, the cross member 13 is provided on the floor panel 10 in front of the vehicle body rather than the jack support portion 12, thereby It is intended to prevent scattering into the room. FIG. 5A is a perspective view showing the peripheral structure of the cross member 13 and the regulating member 14, and FIG. 5B is a cross-sectional view taken along the line II in FIG. 5A.

クロスメンバ１３は、その断面が略コの字形をなしてフロアパネル１０の上面から上方へ突出しており、フロアパネル１０と相俟って閉断面を構成している。クロスメンバ１３は後突時にジャッキＪが車体前方へ移動することを規制する高さを有する、車体後方側の縦壁部１３ａを有する。また、縦壁部１３ａはジャッキＪの車体前後方向の前端と対面する対面部分１３ａ’を有する。ジャッキＪは図５（ｂ）において破線で示すように、ジャッキＪの車体前後方向の前端が対面部分１３ａ’に対面した状態でジャッキ支持部１２に支持される。   The cross member 13 has a substantially U-shaped cross section and protrudes upward from the upper surface of the floor panel 10, and forms a closed cross section together with the floor panel 10. The cross member 13 has a vertical wall portion 13a on the rear side of the vehicle body that has a height that restricts the jack J from moving forward of the vehicle body at the time of a rear collision. The vertical wall portion 13a has a facing portion 13a 'that faces the front end of the jack J in the longitudinal direction of the vehicle body. As shown by a broken line in FIG. 5B, the jack J is supported by the jack support 12 with the front end of the jack J in the longitudinal direction of the vehicle facing the facing portion 13a '.

そして、自動車Ａに後突が発生すると、その衝撃が強度のものであった場合、ジャッキＪはジャッキ支持部１２から外れて車体前方へ飛び出すことになる。しかし、飛び出したジャッキＪは対面部分１３ａ’に衝突する。このため、縦壁部１３ａが抑止壁となってジャッキＪの移動が規制される。従って、ジャッキＪが客室内へ飛散することを防止することができる。縦壁部１３ａは車幅方向に延びる車体構造部材であるクロスメンバ１３の一部であり、クロスメンバ１３はフロアパネル１０上に比較的強固に配設される。このようなクロスメンバ１３を抑止壁として用いることで部品点数の増加や別途の補強構造がなくともジャッキＪの車体前方への移動を規制することができる。なお、本実施形態では、クロスメンバ１３が平面視で、その中央部分が車体前方側に張り出し、相対的に両端部が車体後方側に位置するように湾曲している。このため、ジャッキＪが車体後方寄りで支持されることになり、ジャッキＪを車体後方から取り出し易くなる。それでいながらジャッキＪの前端が縦壁部１３ａと近くなるため、ジャッキＪの車体前方への移動の規制タイミングが早まり、客室内への飛散防止が図れる。   When a rear collision occurs in the automobile A, if the impact is strong, the jack J comes off the jack support portion 12 and jumps out to the front of the vehicle body. However, the jack J that jumps out collides with the facing portion 13a '. For this reason, the vertical wall part 13a becomes a deterrent wall, and the movement of the jack J is controlled. Therefore, it is possible to prevent the jack J from being scattered into the cabin. The vertical wall portion 13 a is a part of the cross member 13 that is a vehicle body structural member extending in the vehicle width direction, and the cross member 13 is disposed relatively firmly on the floor panel 10. By using such a cross member 13 as a deterrent wall, the movement of the jack J to the front of the vehicle body can be restricted without an increase in the number of parts or a separate reinforcement structure. In the present embodiment, the cross member 13 is bent in a plan view so that a central portion thereof protrudes toward the front side of the vehicle body, and both end portions are relatively positioned on the rear side of the vehicle body. For this reason, the jack J is supported near the rear of the vehicle body, and the jack J can be easily taken out from the rear of the vehicle body. Nevertheless, since the front end of the jack J is close to the vertical wall portion 13a, the restriction timing of the movement of the jack J toward the front of the vehicle body is advanced, and scattering into the passenger compartment can be prevented.

次に、規制部材１４について説明する。規制部材１４はジャッキ支持部１２よりも車体前方に配設され、後突時にジャッキＪが車体前方上側へ移動することを規制する。本実施形態の場合、規制部材１４は上板部１４ａと、左右の側板部１４ｂと、から断面がコの字状に形成されている。規制部材１４の前方端部はクロスメンバ１３に固定され、後方端部はジャッキＪに向けて開口しており、クロスメンバ１３から車体後方へ向けて配設されている。   Next, the regulating member 14 will be described. The restricting member 14 is disposed in front of the vehicle body with respect to the jack support portion 12 and restricts the jack J from moving to the upper front side of the vehicle body at the time of a rear collision. In the case of the present embodiment, the regulating member 14 has a U-shaped cross section from the upper plate portion 14a and the left and right side plate portions 14b. The front end portion of the restricting member 14 is fixed to the cross member 13, and the rear end portion opens toward the jack J, and is disposed from the cross member 13 toward the rear of the vehicle body.

車輌の後突時にその衝撃によりジャッキＪがジャッキ支持部１２から外れて車体前方へ移動しようとすると、規制部材１４の上板部１４ａの存在により車体前方上側へ移動することが規制される。従って、ジャッキＪが客室内へ飛散することを防止することができる。また、本実施形態の規制部材１４は側板部１４ｂが設けられているため、後突時にジャッキＪが斜め前方へ飛び出すような場合でも確実に客室内へ飛散することを防止することができる。更に、本実施形態の規制部材１４の前方端部はクロスメンバ１３に固定されている。従って、本実施形態の構成では、規制部材１４はジャッキＪが車体前方上側へ移動することを規制するのみならず、ジャッキＪを縦壁部１３ａに案内する役割も果たす。従って、より効果的にジャッキＪの客室内への飛散が防止される。加えて、後突時にジャッキＪから受ける、規制部材１４に対する車体前方への荷重をクロスメンバ１３に負担させることができ、ジャッキＪの衝突に対して規制部材１４の車体前後方向の強度を向上することができる。従って、後突時におけるジャッキＪの車体前方上側への移動を規制部材１４によってより確実に規制でき、ジャッキＪが客室内へ飛散することをより効果的に防止することができる。   If the jack J is disengaged from the jack support portion 12 due to the impact at the time of the rear impact of the vehicle and tries to move to the front of the vehicle body, it is restricted from moving to the front upper side of the vehicle body due to the presence of the upper plate portion 14a of the restriction member 14. Therefore, it is possible to prevent the jack J from being scattered into the cabin. Further, since the regulation member 14 of the present embodiment is provided with the side plate portion 14b, it is possible to reliably prevent the jack J from splashing into the passenger compartment even when the jack J jumps diagonally forward at the time of a rear collision. Further, the front end portion of the regulating member 14 of the present embodiment is fixed to the cross member 13. Therefore, in the configuration of the present embodiment, the regulating member 14 not only regulates the movement of the jack J to the upper front side of the vehicle body, but also plays a role of guiding the jack J to the vertical wall portion 13a. Therefore, the jack J can be more effectively prevented from scattering into the passenger compartment. In addition, it is possible to load the cross member 13 with a load in front of the vehicle body with respect to the restriction member 14 received from the jack J at the time of a rear collision, and improve the strength of the restriction member 14 in the longitudinal direction of the vehicle body against the collision of the jack J. be able to. Therefore, the movement of the jack J to the upper front side of the vehicle body at the time of a rear collision can be more reliably regulated by the regulating member 14, and the jack J can be more effectively prevented from scattering into the cabin.

次に、本実施形態の場合、図５（ｂ）に示すように、上板部１４ａは車体前方へ向かって下降するように傾斜しており、後突時に車体前方に移動するジャッキＪの前端部を車体前方下側へ案内する傾斜部を構成している。この構成によれば、規制部材１４によりジャッキＪの移動が車体前方下側へ案内され、車体前方上側へ移動することが規制される。従って、ジャッキが客室内へ飛散することをより効果的に防止することができる。更に、上板部１４ａは車体前方へ向かって下降するように傾斜させることにより、規制部材１４は後突時に車体前方に移動するジャッキＪの前端部を対面部分１３ａ’に案内する形状を構成している。このため、規制部材１４の案内によりジャッキＪが縦壁部１３ａに衝突し、縦壁部１３ａが抑止壁となってジャッキＪの客室内への飛散がより効果的に防止される。また、クロスメンバ１３によりジャッキＪの車体前後方向の衝撃荷重が負担されるので、規制部材１４の車体前後方向の剛性を低くすることができ、その小型・軽量化を図ることができる。   Next, in the case of the present embodiment, as shown in FIG. 5B, the upper plate portion 14a is inclined so as to descend toward the front of the vehicle body, and the front end of the jack J that moves forward in the vehicle body at the time of a rear collision. The slope part which guides a part to a vehicle body front lower side is comprised. According to this configuration, the restriction member 14 guides the movement of the jack J to the lower front side of the vehicle body and restricts the movement to the upper front side of the vehicle body. Therefore, it is possible to more effectively prevent the jack from scattering into the cabin. Further, the upper plate portion 14a is inclined so as to descend toward the front of the vehicle body, so that the regulating member 14 forms a shape that guides the front end portion of the jack J that moves to the front of the vehicle body at the time of a rear collision to the facing portion 13a ′. ing. For this reason, the jack J collides with the vertical wall portion 13a by the guide of the regulating member 14, and the vertical wall portion 13a serves as a deterrent wall, and the scattering of the jack J into the cabin is more effectively prevented. Further, since the impact load in the longitudinal direction of the vehicle body of the jack J is borne by the cross member 13, the rigidity of the regulating member 14 in the longitudinal direction of the vehicle body can be reduced, and the size and weight can be reduced.

なお、上板部１４ａをこのように傾斜させた場合、図５（ｂ）に示すように上板部１４ａの後端の高さがクロスメンバ１３よりも高くなる。クロスメンバ１３上にはボード１（図１参照）が載置されるため、上板部１４ａの後端の高さはクロスメンバ１３の高さ以下にすることが望ましい。そこで、図５（ｃ）に示すように、上板部１４ａの前端部分に段差を付け、傾斜の前端部分が低くなるようにすることが望ましい。こうすることで同図に示すように上板部１４ａの後端の高さはクロスメンバ１３の高さ以下にすることができ、後部荷室空間の間仕切り床となるボード１を規制部材１４と干渉することなく平坦にクロスメンバ１３上に支持することができ、それでいながら規制部材１４によって後突時におけるジャッキＪの車体前方上側への移動を規制できる。   When the upper plate portion 14a is inclined in this way, the height of the rear end of the upper plate portion 14a is higher than that of the cross member 13 as shown in FIG. Since the board 1 (see FIG. 1) is placed on the cross member 13, it is desirable that the height of the rear end of the upper plate portion 14a be equal to or less than the height of the cross member 13. Therefore, as shown in FIG. 5C, it is desirable to provide a step in the front end portion of the upper plate portion 14a so that the front end portion of the slope is lowered. By doing so, the height of the rear end of the upper plate portion 14a can be made equal to or less than the height of the cross member 13, as shown in FIG. It can be flatly supported on the cross member 13 without interfering with it, and the movement of the jack J to the upper front side of the vehicle body at the time of the rear collision can be restricted by the restricting member 14.

次に、本実施形態の場合、図５（ｂ）に示すように上板部１４ａはジャッキ支持部１２に支持されたジャッキＪの前端部を上から覆う部分を有している。このため、ジャッキＪが車体前方上側へ移動することがより確実に規制されてジャッキＪが客室内へ飛散することをより効果的に防止することができる。ここで、ジャッキＪをジャッキ支持部１２に取り付ける場合には、車体右後方からジャッキＪの前端部を規制部材１４内に挿入し、当該前端部を中心としてジャッキＪを平面視で時計回りに回動させてジャッキＪの脚部Ｊａを爪部１２１ａに係止し、軸体１２１ｂを取付穴Ｊｂに挿入する。その後、ハンドル１２３を用いて筒体１２２を軸体１２１ｂの上端部に螺合する。   Next, in the present embodiment, as shown in FIG. 5B, the upper plate portion 14a has a portion that covers the front end portion of the jack J supported by the jack support portion 12 from above. For this reason, it is possible to more effectively prevent the jack J from being scattered into the passenger compartment by more reliably restricting the jack J from moving to the upper front side of the vehicle body. Here, when the jack J is attached to the jack support 12, the front end of the jack J is inserted into the regulating member 14 from the right rear side of the vehicle body, and the jack J is rotated clockwise in plan view with the front end as a center. The leg portion Ja of the jack J is locked to the claw portion 121a, and the shaft body 121b is inserted into the mounting hole Jb. Thereafter, the cylindrical body 122 is screwed to the upper end portion of the shaft body 121b using the handle 123.

逆に、ジャッキＪをジャッキ支持部１２から取り外す場合には、この逆の操作となる。取り外す場合、筒体１２２を軸体１２１ｂから取り外した後、ジャッキＪの後方を持ち上げて軸体１２１ｂから取付穴Ｊｂを外しつつ、規制部材１４内に挿入されている前端部を中心として平面視で反時計回りに回動させ、車体後方上側へ引き抜くことができる。このため、規制部材１４がジャッキＪの前端部を上から覆う部分を有していても、ジャッキＪを車体後方上側へ引き抜くことによりジャッキ支持部１２から取り外せるのでジャッキＪの出し入れの作業性が確保される。   Conversely, when the jack J is removed from the jack support 12, this operation is reversed. When removing the cylindrical body 122 from the shaft body 121b, the rear side of the jack J is lifted to remove the mounting hole Jb from the shaft body 121b, and the front end portion inserted into the regulating member 14 is viewed in plan view. It can be rotated counterclockwise and pulled out to the rear upper side of the vehicle body. For this reason, even if the restricting member 14 has a portion that covers the front end of the jack J from above, the jack J can be removed from the jack support portion 12 by pulling the jack J to the rear upper side of the vehicle body, so that the workability of inserting and removing the jack J is ensured. Is done.

次に、本実施形態では、上記構成により、ジャッキＪの客室内への飛散を十分に防止できるが、後突時の衝撃が極めて強度のものであった場合、ジャッキＪが縦壁部１３ａに衝突した後、転動して縦壁部１３ａを乗り越えて車体前方へ移動することも考えられる。そこで、縦壁部１３ａに衝突したジャッキＪをそのまま縦壁部１３ａに係止させる係止部を設けることもできる。   Next, in the present embodiment, the above configuration can sufficiently prevent the jack J from scattering into the passenger compartment. However, when the impact at the time of the rear impact is extremely strong, the jack J is attached to the vertical wall portion 13a. It is also conceivable that after the collision, the vehicle rolls over the vertical wall portion 13a and moves forward of the vehicle body. In view of this, it is possible to provide a locking portion for locking the jack J that has collided with the vertical wall portion 13a to the vertical wall portion 13a as it is.

図６（ａ）は係止部として開口部１３１を設けたクロスメンバ１３及び規制部材１４の周辺構造を示す斜視図、図６（ｂ）は図６（ａ）の線ＩＩ−ＩＩに沿う断面図である。開口部１３１は対面部分１３ａ’に設けられている。後突時にジャッキＪが車体前方へ移動すると、その前端部が開口部１３１に突入し、嵌合状態にて係止される。従って、ジャッキＪが転動して縦壁部１３ａを乗り越えて車体前方へ移動することが防止される。なお、本実施形態では規制部材１４の上板部１４ａを車体前方へ向かって下降するように傾斜させることにより、規制部材１４は後突時に車体前方に移動するジャッキＪの前端部を開口部１３１に案内する形状を有している。このため、規制部材１４によりジャッキＪの前端部が開口部１３１へ案内されるので、より確実にジャッキＪを縦壁部１３ａへ係止させることができる。   6A is a perspective view showing the peripheral structure of the cross member 13 and the regulating member 14 provided with an opening 131 as a locking portion, and FIG. 6B is a cross section taken along line II-II in FIG. 6A. FIG. The opening 131 is provided in the facing portion 13a '. When the jack J moves to the front of the vehicle body at the time of a rear collision, the front end portion enters the opening 131 and is locked in the fitted state. Therefore, it is possible to prevent the jack J from rolling and moving over the vertical wall portion 13a and moving forward. In the present embodiment, the upper end portion 14a of the restriction member 14 is inclined so as to descend toward the front of the vehicle body, whereby the restriction member 14 opens the front end portion of the jack J that moves forward of the vehicle body at the time of a rear collision. It has a shape to guide to. For this reason, since the front end part of the jack J is guided to the opening part 131 by the control member 14, the jack J can be more reliably latched to the vertical wall part 13a.

図６（ｃ）は係止部として傾斜部１３２を設けたクロスメンバ１３及び規制部材１４の周辺構造を示す斜視図、図６（ｄ）は図６（ｃ）の線ＩＩＩ−ＩＩＩに沿う断面図である。傾斜部１３２は対面部分１３ａ’を曲折して形成され、車体前方方向へ向かって下降するように傾斜している。後突時にジャッキＪが車体前方へ移動すると、その前端部が傾斜部１３２に案内されてジャッキＪが縦壁部１３ａの下へ潜り込むように移動し、縦壁部１３ａの変形により縦壁部１３ａに係止される。従って、ジャッキＪが転動して縦壁部１３ａを乗り越えて車体前方へ移動することが防止される。なお、上述した通り、本実施形態では規制部材１４の上板部１４ａを車体前方へ向かって下降するように傾斜させることにより、規制部材１４は後突時に車体前方に移動するジャッキＪの前端部を傾斜部１３２に案内する形状を有している。このため、規制部材１４によりジャッキＪの前端部が傾斜部１３２へ案内されるので、より確実にジャッキＪを縦壁部１３ａへ係止させることができる。また、クロスメンバ１３の閉断面を損なうことはないので、開口部１３１を設ける場合よりも剛性を高めることができる。   6C is a perspective view showing the peripheral structure of the cross member 13 and the regulating member 14 provided with the inclined portion 132 as a locking portion, and FIG. 6D is a cross section taken along line III-III in FIG. 6C. FIG. The inclined portion 132 is formed by bending the facing portion 13a 'and is inclined so as to descend toward the front of the vehicle body. When the jack J moves forward in the rear impact, the front end of the jack J is guided by the inclined portion 132 so that the jack J moves under the vertical wall portion 13a, and the vertical wall portion 13a is deformed by the deformation of the vertical wall portion 13a. It is locked to. Therefore, it is possible to prevent the jack J from rolling and moving over the vertical wall portion 13a and moving forward. As described above, in the present embodiment, the upper end portion 14a of the restriction member 14 is inclined so as to be lowered toward the front of the vehicle body, so that the restriction member 14 moves to the front of the vehicle body at the time of a rear collision. Is guided to the inclined portion 132. For this reason, since the front-end part of the jack J is guided to the inclination part 132 by the control member 14, the jack J can be more reliably latched to the vertical wall part 13a. Further, since the closed cross section of the cross member 13 is not impaired, the rigidity can be increased as compared with the case where the opening 131 is provided.

なお、本実施形態では、規制部材１４とクロスメンバ１３との組合せにより、ジャッキＪが客室内へ飛散することを防止するようにしたが、規制部材１４単独でもジャッキＪの車体前方上側への移動を防止して、客室内への飛散を防止することができる。図７（ａ）は規制部材１４単独の場合の構成を示す規制部材１４の斜視図、図７（ｂ）は図７（ａ）の線ＩＶ−ＩＶに沿う断面図である。   In the present embodiment, the combination of the restriction member 14 and the cross member 13 prevents the jack J from scattering into the passenger compartment. However, even with the restriction member 14 alone, the jack J moves to the upper front side of the vehicle body. Can be prevented, and scattering into the cabin can be prevented. FIG. 7A is a perspective view of the regulating member 14 showing the configuration in the case of the regulating member 14 alone, and FIG. 7B is a cross-sectional view taken along line IV-IV in FIG.

同図の例では、規制部材１４は上板部１４ａと、左右の側板部１４ｂと、から断面がコの字状に形成されており、更に、その前方端部はクロスメンバ１３に固定される代わりに閉鎖されており、全体として後端端部がジャッキＪに向けて開口した袋状をなしている。   In the example of the figure, the regulating member 14 is formed in a U-shaped cross section from an upper plate portion 14 a and left and right side plate portions 14 b, and the front end portion thereof is fixed to the cross member 13. Instead, it is closed, and as a whole, it has a bag shape in which the rear end portion opens toward the jack J.

本例の場合においても、車輌の後突時にその衝撃によりジャッキＪがジャッキ支持部１２から外れて車体前方へ移動しようとすると、規制部材１４の上板部１４ａの存在により車体前方上側へ移動することが規制される。そして、規制部材１４の前方端部が閉じているのでジャッキＪはこれに衝突して前方への移動が抑制される。従って、ジャッキＪが客室内へ飛散することを防止することができる。   Also in the case of this example, if the jack J tries to move forward from the jack support portion 12 due to the impact at the time of the rear collision of the vehicle, it moves to the upper front side of the vehicle body due to the presence of the upper plate portion 14a of the regulating member 14. Is regulated. And since the front-end part of the control member 14 is closed, the jack J collides with this and the movement to the front is suppressed. Therefore, it is possible to prevent the jack J from being scattered into the cabin.
