Description

本発明は、車体下部に配置される車両のサイドステップに関する。   The present invention relates to a side step of a vehicle disposed at a lower part of a vehicle body.

オフロード車など、客室の床面の位置が高い自動車(車両)には、車体下部である乗降口の下側にサイドステップを設けて、乗員を乗り降りしやすくしたものがある。
同サイドステップには、車体側方へ張り出す板状のステップ部を有するだけでなく、当該ステップ部の車体側の側端部から車体下部へ延びる縦壁部を用いて、ステップ部と車体下部との間を縦壁部で遮るようにしたものがある。
Some automobiles (vehicles) such as off-road vehicles with a high floor surface in the passenger compartment have a side step provided on the lower side of the vehicle body at the lower side of the entrance to make it easier for passengers to get on and off.
The side step not only has a plate-like step portion that projects to the side of the vehicle body, but also uses a vertical wall portion that extends from the side end portion on the vehicle body side of the step portion to the vehicle body lower portion. There is something that is blocked by a vertical wall.

こうしたサイドステップでは、安価ですむよう、剛性を重視するステップ部と、剛性を重視しない縦壁部とをそれぞれ別体な部材で形成し、これらを連結部で連結させる、といった構造を採用したものがある。
このような別体式のサイドステップの多くは、連結部として、ステップ部の側端部に、低位な壁部でなる受け座壁を形成し、縦壁部の下端部に下方向が開口する溝部を形成する構造を用いて、横方向から溝部内に受け座壁を嵌挿させることにより、縦壁部をステップ部に支持させていた(特許文献1を参照)。
In such side steps, a step part that places importance on rigidity and a vertical wall part that does not place importance on rigidity are formed of separate members and connected by a connecting part so that the cost is low. is there.
Many of these separate side steps form a receiving seat wall consisting of a lower wall portion at the side end portion of the step portion as a connecting portion, and a groove portion that opens downward at the lower end portion of the vertical wall portion. The vertical wall portion is supported by the step portion by inserting the receiving seat wall into the groove portion from the lateral direction using the structure that forms (see Patent Document 1).

特許第3069238号(特開平7−300084号公報)Japanese Patent No. 3069238 (Japanese Patent Laid-Open No. 7-300084)

ところが、上記連結部は、縦壁部の下端部分だけを溝部に嵌めて、縦壁部を規制する構造のため、縦壁部の振れる方向(車幅方向)に対する支持剛性は十分でなく、縦壁部は嵌挿部分から振れやすい。上記引用文献1では、それを補うため、別途、固定構造を併用している。つまり、連結部だけでは十分な支持剛性の確保に至らなかった。
しかも、縦壁部および溝部は、いずれもサイドステップの長さ方向に連続しているため、縦壁部の組付時(嵌挿時)における摩擦抵抗は大きく、縦壁部の組付作業を面倒なものとしていた。
However, since the connecting portion has a structure in which only the lower end portion of the vertical wall portion is fitted into the groove portion to regulate the vertical wall portion, the support rigidity with respect to the swinging direction of the vertical wall portion (vehicle width direction) is not sufficient. The wall part is likely to swing from the insertion part. In the cited document 1, in order to compensate for this, a fixing structure is separately used together. In other words, sufficient support rigidity cannot be ensured with the connecting portion alone.
In addition, since the vertical wall portion and the groove portion are both continuous in the length direction of the side step, the frictional resistance is large when the vertical wall portion is assembled (at the time of insertion), and the vertical wall portion is assembled. It was annoying.

そこで、本発明の目的は、縦壁部の組付作業の容易化を図りつつ、連結部のもたらす支持剛性だけで、縦壁部が強固にステップ部に組み付けられる車両のサイドステップを提供する。   Therefore, an object of the present invention is to provide a side step of a vehicle in which the vertical wall portion is firmly attached to the step portion only by the support rigidity provided by the connecting portion while facilitating the assembling work of the vertical wall portion.

本発明の態様は、ステップ部と縦壁部を連結する連結部を、ステップ部および縦壁部の一方に設けられステップ部および縦壁部の長手方向に連続して延びるレール状部と、ステップ部および縦壁部の他方に設けられレール状部に対して長手方向に摺動可能に係合されてレール状部を保持する保持部とを有し、レール状部は、上方に開口する第1の係合溝と、同第1の係合溝と反対側を向くよう一対で形成された下方に開口する第2の係合溝とを含んで構成され、保持部は、長手方向に並んで複数設けられ下方へ突出形成されて第1の係合溝に係合される第1の係合爪と、上方へ突出形成されて第2の係合溝に係合される第2の係合爪とを含んで構成されるものとした。   An aspect of the present invention provides a connecting portion that connects a step portion and a vertical wall portion, a rail-like portion that is provided on one of the step portion and the vertical wall portion and extends continuously in the longitudinal direction of the step portion and the vertical wall portion, and a step And a holding portion that is slidably engaged with the rail-like portion in the longitudinal direction and holds the rail-like portion, and the rail-like portion opens upward. 1 holding groove and a second engaging groove that is formed in a pair so as to face the opposite side of the first engaging groove and that opens downward, and the holding portion is arranged in the longitudinal direction. A plurality of first engagement claws that project downward and engage with the first engagement groove, and a second engagement that projects upward and engages with the second engagement groove. It was comprised including the nail | claw.

本発明によれば、保持部の第1、第2の係合爪にレール状部の第1.第2の係合溝が、嵌挿されることにより、複数の係合爪はレール状部に対し上下方向から抱えるように組み付く。これにより、縦壁部は、ステップ部に強固に支持される。つまり、縦壁部には、複数の係合爪の上下方向からの係合により十分な規制力がもたらされ、縦壁部は十分な支持剛性で支持される。しかも、複数の係合爪の採用により、縦壁部の組付(嵌挿)における摩擦抵抗は小さく抑えられ、縦壁部の組付作業(嵌挿作業)は容易になる。   According to the present invention, the first and second engaging claws of the holding portion are provided with the first. By inserting the second engagement groove, the plurality of engagement claws are assembled to the rail-shaped portion so as to be held from above and below. Thereby, the vertical wall portion is firmly supported by the step portion. In other words, the vertical wall portion is provided with sufficient regulating force by the engagement of the plurality of engaging claws from the vertical direction, and the vertical wall portion is supported with sufficient support rigidity. Moreover, by employing a plurality of engaging claws, the frictional resistance in assembling (inserting) the vertical wall portion is kept small, and the assembling operation (inserting operation) of the vertical wall portion is facilitated.

それ故、縦壁部の組付作業の容易化を図りつつ、連結部がもたらす支持剛性だけで縦壁部をステップ部に強固に組み付けることができる。   Therefore, the vertical wall portion can be firmly assembled to the step portion only by the support rigidity provided by the connecting portion while facilitating the assembling work of the vertical wall portion.

以下、本発明を図1から図6に示す一実施形態にもとづいて説明する。
図1は、例えばオフロード車など高床の自動車(車両)の一部、具体的には自動車の側部外観を示していて、図中1は車体、5は同車体1の側部に有るフロント乗降口(図示しない)を開閉するフロントドア、7は車体1の側部に有るリヤ乗降口(図示しない)を開閉するリヤドア、9はフロントフェンダを示している。フロントフェンダ9には前輪(図示しない)が配置され、リヤドア7のリヤ側には後輪(図示しない)が配置される。
Hereinafter, the present invention will be described based on an embodiment shown in FIGS.
FIG. 1 shows a part of a high-floor automobile (vehicle) such as an off-road vehicle, specifically, the side part appearance of the automobile. In FIG. 1, 1 is a vehicle body, and 5 is a front side of the vehicle body 1. A front door that opens and closes a doorway (not shown), 7 is a rear door that opens and closes a rear doorway (not shown) on the side of the vehicle body 1, and 9 is a front fender. A front wheel (not shown) is arranged on the front fender 9, and a rear wheel (not shown) is arranged on the rear side of the rear door 7.

車体1のうち、フロント乗降口およびリヤ乗降口の下側には、サイドステップアッセンブリ11が、サイドステップガーニッシュ13と共に設けられている。
サイドステップアッセンブリ11にはサイドステップ15が含まれている。図2の斜視図にはサイドステップアッセンブリ11の外観が示され、図3の斜視図にはサイドステップアッセンブリ11の各部の構造が示されている。また図4には、図1のサイドステップアッセンブリ11、サイドステップガーニッシュ13の断面(いずれもA−A線)が示されている。
A side step assembly 11 and a side step garnish 13 are provided below the front entrance and the rear entrance in the vehicle body 1.
The side step assembly 11 includes a side step 15. The perspective view of FIG. 2 shows the appearance of the side step assembly 11, and the perspective view of FIG. 3 shows the structure of each part of the side step assembly 11. Further, FIG. 4 shows a cross section (both line AA) of the side step assembly 11 and the side step garnish 13 of FIG.

サイドステップアッセンブリ11には、例えば図2〜図4に示されるようにサイドステップ15に、サイドステップカバー17、サイドステップステー19を組み付けた構造が用いられている。
具体的にはサイドステップ15は、乗員の脚が乗る車両前後方向に延びる帯板状のステップ部21と、車体1との隙間を遮る上記ステップ部21の車体側(車幅方向内側)の側端部から上方へ延びる縦壁部23とを有したL形をなしている。廉価な構造とするためサイドステップ15は、剛性を重視するステップ部21と、剛性を重視しない縦壁部23とを別体にしている。剛性を重視するステップ部21は、例えばアルミ部材の押し出し成形で成形された金属製のステップが用いられる。また剛性を重視しない縦壁部23は、例えば廉価なコストですむよう、合成樹脂の射出成形で成形された合成樹脂製の長尺な壁部が用いられる。これら金属製のステップと合成樹脂製の壁部とが連結部24で連結されている。この連結部24の構造については後述する。
For example, as shown in FIGS. 2 to 4, the side step assembly 11 has a structure in which a side step cover 17 and a side step stay 19 are assembled to a side step 15.
Specifically, the side step 15 is a vehicle body side (inward in the vehicle width direction) side of the step portion 21 that blocks a gap between the strip plate-like step portion 21 extending in the vehicle front-rear direction on which the passenger's legs ride and the vehicle body 1. It has an L shape having a vertical wall portion 23 extending upward from the end portion. In order to obtain an inexpensive structure, the side step 15 has a step part 21 that emphasizes rigidity and a vertical wall part 23 that does not emphasize rigidity as separate bodies. As the step portion 21 that places importance on rigidity, for example, a metal step formed by extrusion molding of an aluminum member is used. For the vertical wall portion 23 that does not place importance on rigidity, for example, a long wall portion made of synthetic resin formed by injection molding of synthetic resin is used so that the cost is low. These metal steps and synthetic resin wall portions are connected by a connecting portion 24. The structure of the connecting portion 24 will be described later.

ステップ部21の長手方向の両端部および車体外側(車幅方向外側)の側端部は、図2および図3に示されるように射出成形品で形成された長尺のサイドステップカバー17で覆われる。さらにステップ部21の下部の複数個所、例えば3個所には、L形に成形されたサイドステップステー19が取着され、サイドステップアッセンブリ11全体を構成している。   Both end portions in the longitudinal direction of the step portion 21 and side end portions on the vehicle body outer side (vehicle width direction outer side) are covered with a long side step cover 17 formed of an injection-molded product as shown in FIGS. Is called. Furthermore, L-shaped side step stays 19 are attached to a plurality of lower portions of the step portion 21, for example, three locations, thereby constituting the entire side step assembly 11.

そして、上方へ突き出る各サイドステップステー19の上端部は、車体下部に配置された車体骨格部材、例えばフロント乗降口の下部に配置されたサイドシル部材27に固定され、図1および図4に示されるようにステップ部21は、車体下部から車体側方(車幅方向外側)へ張り出した姿勢に取り付けられている。そして、縦壁部23は、その上端部がサイドシル部材27の下端部である、サイドシルインナパネル29a、サイドシルアウタパネル29b、リンフォースパネル29cが合わさった下端部のフランジ部29dの外側(車幅方向)に位置するよう配置される。   And the upper end part of each side step stay 19 which protrudes upwards is fixed to the vehicle body frame member arrange | positioned at the vehicle body lower part, for example, the side sill member 27 arrange | positioned at the lower part of a front entrance / exit, and is shown by FIG. 1 and FIG. Thus, the step part 21 is attached to the attitude | position which protruded from the vehicle body lower part to the vehicle body side (vehicle width direction outer side). And the vertical wall part 23 is the lower end part of the side sill member 27 whose upper end part is the lower end part of the side sill member 27, outside the flange part 29d of the lower end part combined with the side sill inner panel 29a, the side sill outer panel 29b, and the reinforcement panel 29c (vehicle width direction). It arrange | positions so that it may be located in.

このステップ部21と車体1下部との間に、上記サイドステップガーニッシュ13が介装され、サイドステップガーニッシュ13にて、縦壁部23と車体下部との隙間や、ステップ部21側部を覆うサイドステップカバー17の側部分17aと車体下部との隙間や、縦壁部23の下端側を遮っている。
縦壁部23の上端部には、図2に示されるように凹壁部25が形成されている。凹壁部25は、サイドシル部材27の下端へ突き出るフランジ部29d(パネル端同士が合わさった部分)の先端部を周囲から囲みつつ、フランジ部29dの下端部と縦壁部23との隙間を遮るC形の壁部で形成される。この凹壁部25により、ステップ部21へ向かう泥水の侵入経路を断ち、さらにはフランジ部29dを伝い落ちる泥水が凹壁部25内に溜まるようにしている。
The side step garnish 13 is interposed between the step portion 21 and the lower portion of the vehicle body 1, and the side step garnish 13 covers the gap between the vertical wall portion 23 and the lower portion of the vehicle body and the side portion of the step portion 21. The gap between the side portion 17a of the step cover 17 and the lower part of the vehicle body and the lower end side of the vertical wall portion 23 are blocked.
A concave wall portion 25 is formed at the upper end portion of the vertical wall portion 23 as shown in FIG. The concave wall portion 25 blocks the gap between the lower end portion of the flange portion 29d and the vertical wall portion 23 while surrounding the distal end portion of the flange portion 29d protruding to the lower end of the side sill member 27 (the portion where the panel ends are joined together) from the periphery. It is formed with a C-shaped wall. The concave wall portion 25 cuts off the muddy water ingress path toward the step portion 21, and further, the muddy water flowing down the flange portion 29 d is accumulated in the concave wall portion 25.

この荷重(外力)が加わりやすい縦壁部23は、ばたつきが生じないよう高い支持剛性で、ステップ部21に連結させることが求められる。そのため、連結部24には、当該要求に応える構造が用いられている。同連結部24には、上下方向から、縦壁部23側あるいはステップ部21側を抱えて保持する構造が用いられている。同構造には、例えば図4に示されるようにステップ部21に、長手方向(車両前後方向)に沿って延び、開口が上下方向で互いに反対に向く上下一対の係合溝33が形成されたレール状部31を設け、縦壁部23に、上記上下一対の係合溝33に上下から嵌る複数の係合爪47を点在させた保持部41を設け、保持部41の係合爪47をレール状部31の係合溝33に横方向からステップ部21の長手方向に摺動して組付(嵌挿)することにより、レール状部31と保持部41とが係合される構造が用いられている。この連結部24の具体的な構造が図5および図6に示されている。   The vertical wall portion 23 to which this load (external force) is easily applied is required to be connected to the step portion 21 with high support rigidity so as not to flutter. Therefore, a structure that meets the demand is used for the connecting portion 24. The connecting portion 24 has a structure that holds and holds the vertical wall portion 23 side or the step portion 21 side from the vertical direction. In this structure, for example, as shown in FIG. 4, a pair of upper and lower engaging grooves 33 extending in the longitudinal direction (vehicle longitudinal direction) and having openings facing each other in the vertical direction are formed in the step portion 21. A rail-shaped portion 31 is provided, and a holding portion 41 in which a plurality of engaging claws 47 fitted from above and below are provided on the vertical wall portion 23 in the vertical pair of engaging grooves 33, and the engaging claws 47 of the holding portion 41 are provided. The rail-shaped portion 31 and the holding portion 41 are engaged with each other by sliding (assembling) the rail into the engaging groove 33 of the rail-shaped portion 31 from the lateral direction in the longitudinal direction of the step portion 21. Is used. The specific structure of the connecting portion 24 is shown in FIGS.

図4〜図6を参照して連結部24の各部について説明すると、ステップ部21の車体側(車幅方向内側)の側端部には、ステップ部21と連続する低位な起立壁21aが一体で形成され、この起立壁21aを介してレール状部31が設けられている。レール状部31はステップ部21の長手方向(車両前後方向)に沿って延びている。このレール状部31の上端部と下端部にそれぞれ第1の係合溝33aと第2の係合溝33bとが形成され、上下一対の係合溝33としている。   Each part of the connecting portion 24 will be described with reference to FIGS. 4 to 6. A lower standing wall 21 a continuous with the step portion 21 is integrally formed with a side end portion of the step portion 21 on the vehicle body side (in the vehicle width direction). The rail-shaped part 31 is provided through this standing wall 21a. The rail-shaped part 31 extends along the longitudinal direction (vehicle longitudinal direction) of the step part 21. A first engagement groove 33 a and a second engagement groove 33 b are respectively formed at the upper end portion and the lower end portion of the rail-shaped portion 31, and a pair of upper and lower engagement grooves 33 is formed.

具体的にはレール状部31は、例えば図5および図6に示されるように起立壁21aの車体側(車幅方向内側)に配置される縦壁でなる帯形の座壁35と、同座壁35の車外側(車幅方向外側)の側面(ステップ部21側)の上段部から上側に座壁35と並行にL形に張り出した上方側L形壁37と、下段部から下側に座壁41と並行に逆L形に張り出した下方側L形壁39とを有している。この上段に位置する上方側L形壁37と座壁35の上端部とで囲まれる凹部分から、上方に開口が向く第1の係合溝33aを形成し、下段に位置する下方側L形壁39と座壁35の下端部とで囲まれる凹部分から、第1の係合溝33aと反対側に位置して下方に開口が向く第2の係合溝33bを形成している。このうちの下方側L形壁39(下段)の先端部が、起立壁21aと一体に連なり、起立壁21aから車体側(車幅方向内側)に上下一対の係合溝33を配置している。なお、レール状部31全体(座壁、L形壁、係合溝を含む)は、ステップ部21と共に、アルミ部材の押出成形品で一体に形成されている(高い剛性の確保)。   Specifically, the rail-shaped portion 31 is similar to a belt-shaped seat wall 35 formed of a vertical wall disposed on the vehicle body side (inner side in the vehicle width direction) of the standing wall 21a as shown in FIGS. 5 and 6, for example. An upper L-shaped wall 37 projecting in an L shape in parallel with the seat wall 35 from the upper step portion of the side surface (step portion 21 side) on the vehicle outer side (vehicle width direction outer side) of the seat wall 35, and the lower side from the lower step portion And a lower L-shaped wall 39 projecting in an inverted L shape in parallel with the seat wall 41. A first engagement groove 33a having an opening facing upward is formed from a concave portion surrounded by the upper L-shaped wall 37 positioned on the upper stage and the upper end of the seat wall 35, and the lower L-shaped wall positioned on the lower stage. A second engagement groove 33b is formed from the concave portion surrounded by 39 and the lower end of the seat wall 35. The second engagement groove 33b is positioned on the opposite side of the first engagement groove 33a and the opening faces downward. Of these, the tip of the lower L-shaped wall 39 (lower stage) is continuous with the upright wall 21a, and a pair of upper and lower engaging grooves 33 are arranged from the upright wall 21a to the vehicle body side (in the vehicle width direction). . Note that the entire rail-shaped portion 31 (including the seat wall, the L-shaped wall, and the engagement groove) is integrally formed with an extruded product of an aluminum member together with the step portion 21 (ensuring high rigidity).

一方、縦壁部23の車外側(車幅方向外側)には、上記保持部41が設けられている。保持部41には、図4および図5に示されるように縦壁部23の長手方向(車両前後方向)に亘って車体側(車幅方向内側)に凹陥され、レール状部材31の座壁35が嵌まる帯形の凹陥部43が形成されている。この凹陥部43の上部縁からは、例えば所定の間隔で、複数の第1の係合爪47aが下方へ突き出ている。また凹陥部43の下部縁からは、例えば所定の間隔で、複数の第2の係合爪47bが上方へ突き出ている。これら上下の第1、第2の係合爪47a,47bは、例えば互い違いに配置され、これら第1、第2の係合爪47a,47bと凹陥部43との間の隙間に、座壁35が挿入可能な嵌挿路45を形成している(図4(b))。これら第1、第2の係合爪47a,47bは、レール状部31の上下一対の第1、第2の係合溝33a,33bとそれぞれ嵌挿可能な外形(例えば板形)に形成されており、レール状部31と上下方向から係合可能に構成されている。ちなみに第1、第2の係合爪47a,47bの外面には、相手側へ突き出る突部、例えば先端が円弧形の突条48が設けられている(図4(b))。   On the other hand, the holding portion 41 is provided on the vehicle outer side (vehicle width direction outer side) of the vertical wall portion 23. As shown in FIGS. 4 and 5, the holding portion 41 is recessed toward the vehicle body side (in the vehicle width direction) over the longitudinal direction (vehicle longitudinal direction) of the vertical wall portion 23, and the seat wall of the rail-shaped member 31 is formed. A band-shaped recessed portion 43 into which 35 is fitted is formed. A plurality of first engaging claws 47a protrude downward from the upper edge of the recessed portion 43, for example, at a predetermined interval. A plurality of second engaging claws 47b protrude upward from the lower edge of the recessed portion 43, for example, at a predetermined interval. The upper and lower first and second engaging claws 47 a and 47 b are arranged alternately, for example, and the seat wall 35 is disposed in the gap between the first and second engaging claws 47 a and 47 b and the recessed portion 43. Is formed into a fitting insertion path 45 (FIG. 4B). The first and second engaging claws 47a and 47b are formed in outer shapes (for example, plate shapes) that can be respectively inserted into the upper and lower paired first and second engaging grooves 33a and 33b of the rail-shaped portion 31. It is configured to be able to engage with the rail-shaped portion 31 from the vertical direction. Incidentally, on the outer surface of the first and second engaging claws 47a and 47b, a protruding portion protruding toward the other side, for example, a protrusion 48 having an arcuate tip is provided (FIG. 4B).

なお、第1、第2の係合爪47a,47bは、縦壁部23(凹陥部、凹壁部、突条を含む)と共に、射出成形で成形され、低廉価を図っている。また凹陥部43の一部には、開口50が形成されていて(図5)、レール状部31と接触する部分の面積を減少させている。開口50は、第1、第2の係合爪47a,47bを射出成形で成形するときに用いる抜き部分をそのまま活用したものである。本実施形態では、凹陥部43の第1の係合爪47aと対向する部分に開口50(開口部に相当)が形成されており、これによりレール部材31(座壁35)との摩擦抵抗をより少なくしている。もちろん、開口50は、第2の係合爪47bと対向する部分に設けても、両者、すなわち第1、第2の係合爪47a,47bと対向する部分の双方に設けて構わない。   The first and second engaging claws 47a and 47b are formed by injection molding together with the vertical wall portion 23 (including the recessed portion, the recessed wall portion, and the ridge), and are inexpensive. In addition, an opening 50 is formed in a part of the recessed portion 43 (FIG. 5), and the area of the portion in contact with the rail-shaped portion 31 is reduced. The opening 50 is made by utilizing the punched portion used when the first and second engaging claws 47a and 47b are formed by injection molding. In the present embodiment, an opening 50 (corresponding to the opening) is formed in a portion of the recessed portion 43 that faces the first engaging claw 47a, and thereby the frictional resistance with the rail member 31 (the seat wall 35) is reduced. Less. Of course, the opening 50 may be provided in a portion facing the second engagement claw 47b, or may be provided in both, that is, both the portions facing the first and second engagement claws 47a and 47b.

このように構成される連結部24は、図3および図5に示されるように第1、第2の係合爪47a,47bを第1、第2の係合溝33a,33bに嵌め、凹陥部43を座壁35に嵌めて、嵌挿路45沿いに縦壁部23をステップ部21と同等位置になるまで長手方向にスライドする。すると、図4および図6に示されるように上下一対の第1、第2の係合溝33a,33bには、点在した複数の第1、第2の係合爪47a,47bが上下方向から嵌挿される。これにより、第1、第2の係合爪47a,47bは、一対の第1、第2の係合溝33a,33bをなすレール状部31の上下端(座壁35、L形壁37,39)に対し上下方向から抱えるように組み付く。つまり、連結部24は、レール状部31の座壁35を保持部41の凹陥部43と第1、第2の係合爪47a,47bとで抱えるように保持することでステップ部21と縦壁部23とを連結している。そして、位置ずれしないよう固定部材、例えば座壁35と凹陥部43との間を貫通するリベット53(図6)で固定することにより、連結部24によるステップ部21と縦壁部23との組み付けを終える。ちなみに、図3中53aは、凹陥部43に設けたリベット孔を示している。   As shown in FIGS. 3 and 5, the connecting portion 24 configured in this way fits the first and second engaging claws 47 a and 47 b into the first and second engaging grooves 33 a and 33 b, The portion 43 is fitted to the seat wall 35, and the vertical wall portion 23 is slid in the longitudinal direction along the fitting insertion path 45 until it reaches the same position as the step portion 21. Then, as shown in FIGS. 4 and 6, a plurality of first and second engaging claws 47a and 47b scattered in the pair of upper and lower first and second engaging grooves 33a and 33b in the vertical direction. It is inserted from. Thus, the first and second engaging claws 47a and 47b are connected to the upper and lower ends (the seat wall 35, the L-shaped wall 37, and the like of the rail-shaped portion 31 forming the pair of first and second engaging grooves 33a and 33b. 39) Assemble it from above and below. That is, the connecting portion 24 holds the seat wall 35 of the rail-shaped portion 31 so as to be held by the recessed portion 43 of the holding portion 41 and the first and second engaging claws 47a and 47b, thereby vertically The wall portion 23 is connected. Then, by fixing with a fixing member, for example, a rivet 53 (FIG. 6) penetrating between the seat wall 35 and the recessed portion 43 so as not to be displaced, the step portion 21 and the vertical wall portion 23 are assembled by the connecting portion 24. Finish. Incidentally, reference numeral 53 a in FIG. 3 denotes a rivet hole provided in the recessed portion 43.

これにより、縦壁部23は、ステップ部21に強固に連結される。すなわち、縦壁部23は、保持部41の第1、第2の係合爪47a,47bがもたらす上下方向からの係合作用により、レール状部31に下端から上端までの広い部分を抱きかかえるように組み付く。これで、縦壁部23には、同縦壁部23の振れる方向(車幅方向)に対し十分な規制力が得られる。つまり、縦壁部23は十分なる支持剛性でステップ部21に連結される。   Thereby, the vertical wall portion 23 is firmly connected to the step portion 21. That is, the vertical wall portion 23 holds a wide portion from the lower end to the upper end on the rail-like portion 31 by the engaging action from the vertical direction provided by the first and second engaging claws 47a and 47b of the holding portion 41. Assemble as follows. Thus, the vertical wall portion 23 is provided with a sufficient regulating force with respect to the swinging direction (vehicle width direction) of the vertical wall portion 23. That is, the vertical wall portion 23 is connected to the step portion 21 with sufficient support rigidity.

しかも、複数の第1、第2の係合爪47a,47bを嵌合させる構造とするとともに凹陥部43の第1の係合爪47aと対向する部分に開口50(開口部)を形成し、縦壁部23とレール状部31(座壁35)との接触面積が少なくなるよう構成しているので、縦壁部23の組付時(嵌挿時)における摩擦抵抗が小さく抑えられ、縦壁部23の組付作業(嵌挿作業)は容易になる。   In addition, the first and second engaging claws 47a and 47b are configured to fit together, and an opening 50 (opening) is formed in a portion of the recessed portion 43 that faces the first engaging claw 47a. Since the contact area between the vertical wall portion 23 and the rail-shaped portion 31 (seat wall 35) is reduced, the frictional resistance when the vertical wall portion 23 is assembled (at the time of insertion) is suppressed to a low level. The assembly work (insertion work) of the wall portion 23 becomes easy.

したがって、縦壁部23の組付作業の容易化を図りつつ、連結部24のもたらす支持剛性だけで、縦壁部23をステップ部21に強固に組み付けることができる。
しかも、突条48は、図4(b)に示されるように係合部間、すなわち座壁41とL形壁43a,43bの間(係合溝33と係合爪47間)に侵入して、がたつきの要因を解消するから、たとえ部品精度のばらつきにより、所定の係合状態が確保され難い場合でも、強固なるステップ部21と縦壁部23との連結ができる。
Therefore, the vertical wall portion 23 can be firmly assembled to the step portion 21 only by the support rigidity provided by the connecting portion 24 while facilitating the assembling work of the vertical wall portion 23.
Moreover, as shown in FIG. 4B, the protrusion 48 enters between the engaging portions, that is, between the seat wall 41 and the L-shaped walls 43a and 43b (between the engaging groove 33 and the engaging claw 47). Since the cause of shakiness is eliminated, even when the predetermined engagement state is difficult to be ensured due to variations in component accuracy, the strong step portion 21 and the vertical wall portion 23 can be connected.

また、第1の係合爪47aと第2の係合爪47bとは交互に配置されるので、レール状部31を上下からバランスよく保持することができ、縦壁部23をステップ部21により強固に組み付けることができる。
そのうえ、係合溝33は、ステップ部21と共に押出成形で形成されるので、製作コストは安価である。加えて係合爪47は、縦壁部23と共に射出成形で形成されるので、どのような位置に点在されたり、どのような形状になっても、容易に対応できる利点がある。
Further, since the first engaging claws 47a and the second engaging claws 47b are alternately arranged, the rail-like portion 31 can be held in a balanced manner from above and below, and the vertical wall portion 23 can be held by the step portion 21. It can be firmly assembled.
In addition, since the engaging groove 33 is formed by extrusion molding together with the step portion 21, the manufacturing cost is low. In addition, since the engaging claw 47 is formed by injection molding together with the vertical wall portion 23, there is an advantage that it can be easily handled regardless of the position where it is scattered or in any shape.

なお、上述した一実施形態における各構成および組合わせ等は一例であり、本発明の趣旨から逸脱しない範囲内で、構成の付加、省略、置換、およびその他の変更が可能であることはいうまでもない。また本発明は、一実施形態によって限定されることはなく、「特許請求の範囲」によってのみ限定されることはいうまでもない。例えば上述した一実施形態では、ステップ部に係合溝を形成し、縦壁部に係合爪を形成したが、これに限らず、ステップ部に係合爪を形成し、縦壁部に係合溝を形成した構造でもよい。   It should be noted that each configuration and combination in the above-described embodiment is an example, and it is needless to say that additions, omissions, substitutions, and other modifications of the configuration can be made without departing from the spirit of the present invention. Nor. Further, the present invention is not limited by the embodiment, and needless to say, is limited only by the “claims”. For example, in the above-described embodiment, the engaging groove is formed in the step portion and the engaging claw is formed in the vertical wall portion. However, the present invention is not limited thereto, and the engaging claw is formed in the step portion and the engaging portion is engaged in the vertical wall portion. A structure in which a groove is formed may be used.
