That is, the battery support 31 and the battery tray 32 correspond to the battery support member of the present invention, and the clamp bolt 36 and the nut 38 correspond to the connection member of the present invention.

＜クランプ受け部４０について＞
クランプ受け部４０は、クランプボルト３６に対してナット３８が締付けられるときに、バッテリクランプ３４の基端部３４ｙが浮き上がろうとするのを上から押える部分である。即ち、クランプ受け部４０は、バッテリクランプ３４の基端部３４ｙを上から押えて支える部材であり、図２、図４（Ａ）に示すように、ロアバック２０の前面を構成する板状の受け部本体４３を備えている。受け部本体４３は、ロアバック２０のインナパネル２２に継ぎ足された角形の鋼板であり、前記インナパネル２２よりも肉厚寸法が大きく設定されている。即ち、ロアバック２０のインナパネル２２が、例えば、0.65mmの鋼板により構成されているのに対し、クランプ受け部４０の受け部本体４３は1.6mmの鋼板により構成されている。このため、ロアバック２０においてクランプ受け部４０の部分の強度が向上している。 <About the clamp receiver 40>
The clamp receiving portion 40 is a portion that presses the base end portion 34y of the battery clamp 34 from floating upward when the nut 38 is tightened against the clamp bolt 36. In other words, the clamp receiving portion 40 is a member that supports the base end portion 34y of the battery clamp 34 by pressing it from above, and as shown in FIGS. 2 and 4A, a plate-shaped receiving portion constituting the front surface of the lower back 20. A main part 43 is provided. The receiving portion main body 43 is a rectangular steel plate joined to the inner panel 22 of the lower back 20, and has a wall thickness larger than that of the inner panel 22. That is, while the inner panel 22 of the lower back 20 is made of, for example, a 0.65 mm steel plate, the receiving portion main body 43 of the clamp receiving portion 40 is made of a 1.6 mm steel plate. For this reason, the strength of the portion of the clamp receiving portion 40 in the lower back 20 is improved.

クランプ受け部４０の受け部本体４３には、図４（Ａ）（Ｂ）に示すように、その受け部本体４３の中央位置に前記バッテリクランプ３４の基端部３４ｙが挿通される左右に長い長穴形の筒状開口部４５が形成されており、その筒状開口部４５の周縁に略楕円形をした座部４７（図４（Ｃ）参照）が設けられている。ここで、クランプ受け部４０の受け部本体４３は、後部車室１４の床面ＦＬよりも低い位置に設けられている。そして、クランプ受け部４０の筒状開口部４５と座部４７とが、図４（Ｃ）に示すように、斜め前下方を指向して設けられている。即ち、座部４７は、筒状開口部４５よりも上側部分が受け部本体４３に対して前方に突出し、筒状開口部４５よりも下側部分が受け部本体４３に対して窪んでおり、その筒状開口部４５の厚み方向（筒の軸方向）に延びる仮想直線が前方で低くなるように傾斜している。
クランプ受け部４０の筒状開口部４５と座部４７との境界部分は角部となっており、その筒状開口部４５の上側に位置する角部Ｋ（以後、上側境界部Ｋという）がバッテリクランプ３４の基端部３４ｙの窪み上面Ｕに当接するようになっている。ここで、バッテリクランプ３４の基端部３４ｙの窪み上面Ｕは、図４（Ｃ）（Ｄ）等に示すように、バッテリクランプ３４の幅方向に延びる断面略円弧形をした溝状に形成されている。
即ち、クランプ受け部４０の上側境界部Ｋがバッテリクランプ３４の窪み上面Ｕに当接してそのバッテリクランプ３４を上から押えることで、バッテリクランプ３４の基端部３４ｙがクランプ受け部４０によって支えられる。このため、バッテリクランプ３４の基端部３４ｙがクランプ受け部４０の筒状開口部４５から前方に抜け難くなる。 As shown in FIGS. 4 (A) and 4 (B), the receiving portion main body 43 of the clamp receiving portion 40 is long to the left and right so that the base end portion 34y of the battery clamp 34 is inserted into the central position of the receiving portion main body 43. A long hole-shaped cylindrical opening 45 is formed, and a substantially elliptical seat 47 (see FIG. 4C) is provided on the periphery of the cylindrical opening 45. Here, the receiving portion main body 43 of the clamp receiving portion 40 is provided at a position lower than the floor surface FL of the rear casing 14. And the cylindrical opening part 45 and the seat part 47 of the clamp receiving part 40 are provided in the diagonally downward direction as shown in FIG.4 (C). That is, the seat 47 has an upper portion protruding from the receiving body 43 with respect to the cylindrical opening 45, and a lower portion with respect to the receiving body 43 from the cylindrical opening 45 is recessed. An imaginary straight line extending in the thickness direction of the cylindrical opening 45 (in the axial direction of the cylinder) is inclined so as to be lowered at the front.
A boundary portion between the cylindrical opening 45 and the seat portion 47 of the clamp receiving portion 40 is a corner portion, and a corner portion K (hereinafter referred to as an upper boundary portion K) located above the cylindrical opening portion 45 is formed. The battery clamp 34 comes into contact with the upper surface U of the recess of the base end portion 34y. Here, the concave upper surface U of the base end portion 34y of the battery clamp 34 is formed in a groove shape having a substantially arc-shaped cross section extending in the width direction of the battery clamp 34, as shown in FIGS. Has been.
That is, the upper boundary portion K of the clamp receiver 40 abuts against the upper surface U of the battery clamp 34 and presses the battery clamp 34 from above, so that the base end portion 34y of the battery clamp 34 is supported by the clamp receiver 40. . For this reason, it becomes difficult for the base end part 34y of the battery clamp 34 to come forward from the cylindrical opening 45 of the clamp receiving part 40.

＜バッテリＢＴの固定手順について＞
バッテリ固定装置３０によって、バッテリＢＴを固定する場合には、バッテリ支持台３１にバッテリ受け皿３２を載せ、そのバッテリ受け皿３２にバッテリＢＴをセットする。次に、バッテリクランプ３４の基端部３４をクランプ受け部４０の筒状開口部４５に挿通し、そのバッテリクランプ３４をバッテリＢＴの上面にセットする。この状態で、図４（Ｃ）（Ｄ）に示すように、クランプ受け部４０の上側境界部Ｋがバッテリクランプ３４の基端部３４の窪み上面Ｕに当接するようになる。次に、クランプボルト３６の鉤部３６ｋがバッテリ支持台３１の受け穴３１ｈに掛けられ、クランプボルト３６の上端部がバッテリクランプ３４の貫通孔３４ｋに通された状態で、そのクランプボルト３６の上端部にナット３８が螺合される。この状態で、ナット３８が締付られることで、バッテリクランプ３４がバッテリＢＴの上面を押圧するようになり、バッテリＢＴの固定が完了する。 <Battery BT fixing procedure>
When the battery BT is fixed by the battery fixing device 30, the battery tray 32 is placed on the battery support base 31, and the battery BT is set on the battery tray 32. Next, the base end portion 34 of the battery clamp 34 is inserted into the cylindrical opening 45 of the clamp receiving portion 40, and the battery clamp 34 is set on the upper surface of the battery BT.

＜本実施形態に係るバッテリ固定装置３０の長所について＞
本実施形態に係るバッテリ固定装置３０によると、クランプ受け部４０は、車両のリヤバンパ２８を支持するロアバック２０の前面側に形成されている。即ち、クランプ受け部４０はロアバック２０の一部を構成している。このため、従来のように、バッテリＢＴのバッテリ支持台３１、バッテリ受け皿３２（支持部材）の横にクランプ受け部を単独で立設する必要がなくなり、クランプ受け部の製作コストを低減させることができる。また、クランプ受け部を支えるサポートも省略できる。
また、クランプ受け部４０は、後部車室１４の床面ＦＬよりも低い位置に形成されているため、バッテリＢＴ及びそのバッテリ固定装置３０が邪魔になることがない。 <Advantages of the battery fixing device 30 according to the present embodiment>
According to the battery fixing device 30 according to the present embodiment, the clamp receiver 40 is formed on the front side of the lower back 20 that supports the rear bumper 28 of the vehicle. That is, the clamp receiving part 40 constitutes a part of the lower back 20. For this reason, unlike the prior art, it is no longer necessary to stand the clamp receiving part separately beside the battery support base 31 and the battery tray 32 (supporting member) of the battery BT, and the manufacturing cost of the clamp receiving part can be reduced. it can. Further, the support for supporting the clamp receiving portion can be omitted.
Moreover, since the clamp receiving part 40 is formed in the position lower than the floor surface FL of the rear compartment 14, the battery BT and its battery fixing device 30 do not get in the way.

また、本実施形態によると、クランプ受け部４０の座部４７と筒状開口部４５との上側境界部Ｋがバッテリクランプ３４の断面略円弧状の窪み上面Ｕに当接する構成のため、バッテリクランプ３４がクランプ受け部４０の筒状開口部４５から抜け難くなる。したがって、バッテリＢＴがクランプ受け部４０及びロアバック２０に対して位置ずれし難くなる。
また、クランプ受け部４０を構成する板材の厚み寸法がロアバック２０を構成する板材の厚み寸法よりも大きく設定されているため、クランプ受け部４０の強度を確保できる。 In addition, according to the present embodiment, since the upper boundary portion K between the seat portion 47 of the clamp receiving portion 40 and the cylindrical opening 45 is in contact with the upper surface U of the battery clamp 34 having a substantially arcuate cross section, the battery clamp 34 is difficult to be removed from the cylindrical opening 45 of the clamp receiving portion 40. Therefore, it is difficult for the battery BT to be displaced with respect to the clamp receiver 40 and the lower back 20.
Further, since the thickness dimension of the plate material constituting the clamp receiving portion 40 is set larger than the thickness dimension of the plate material constituting the lower back 20, the strength of the clamp receiving portion 40 can be ensured.

＜変更例＞
ここで、本発明は上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲における変更が可能である。例えば、本実施形態に係るバッテリ固定装置３０では、クランプ受け部４０に筒状開口部４５を形成し、バッテリクランプ３４の基端部３４ｙを筒状開口部４５に挿通させることで、そのバッテリクランプ３４の基端部３４ｙを前記クランプ受け部４０で支える例を示した。しかし、バッテリクランプ３４の基端部３４ｙを、例えば、ヒンジ機構等を備えるクランプ受け部により上下回動可能な状態で支える構成でも可能である。
また、本実施形態では、クランプ受け部４０の受け部本体４３をロアバック２０のインナパネル２２よりも肉厚寸法の大きな板材で形成する例を示したが、その受け部本体４３をインナパネル２２の表面に重ねる構成にすれば、受け部本体４３の肉厚寸法をインナパネル２２の肉厚寸法とほぼ等しくすることも可能である。 <Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in the battery fixing device 30 according to the present embodiment, a cylindrical opening 45 is formed in the clamp receiving portion 40, and the base end portion 34 y of the battery clamp 34 is inserted into the cylindrical opening 45, so that the battery clamp The example which supports the base end part 34y of 34 with the said clamp receiving part 40 was shown. However, a configuration in which the base end portion 34y of the battery clamp 34 is supported in a state in which the base end portion 34y can be vertically rotated by a clamp receiving portion having a hinge mechanism or the like is also possible.
Moreover, in this embodiment, although the example which forms the receiving part main body 43 of the clamp receiving part 40 with a board | plate material with a larger thickness than the inner panel 22 of the lower back 20 was shown, the receiving part main body 43 of the inner panel 22 is shown. If the structure is superposed on the surface, it is possible to make the thickness dimension of the receiving portion main body 43 substantially equal to the thickness dimension of the inner panel 22.
