　本発明の一形態の車両のバッテリ収納装置は、バッテリ（６２Ａ，６２Ｂ）を収納するバッテリケース（４２）と、前記バッテリケース（４２）に収納された前記バッテリ（６２Ａ，６２Ｂ）の端子部（４１）に接続されるケース側接続端子（４３）と、を備えた車両のバッテリ収納装置において、前記ケース側接続端子（４３）を、前記バッテリ（６２Ａ，６２Ｂ）の端子部（４１）に接触接続する接続位置（Ｐ１）と、当該接続位置（Ｐ１）から離間した退避位置（Ｐ２）との間で変位させる端子変位機構（４５）を備え、前記ケース側接続端子（４３）は、複数の端子ピン（１４０，１４１）を横並び一列に配列されて成り、複数の前記端子ピン（１４０，１４１）のうちの高圧の端子ピン（１４０）は、複数の前記端子ピン（１４０，１４１）の並び方向の端部に配置され、前記高圧の端子ピン（１４０）には、電力ケーブル（１４２）が接続されるとともに、固定手段（１４６）によって接続状態が維持されていることを特徴とする。 A battery storage device of a vehicle according to an aspect of the present invention includes a battery case (42) for storing a battery (62A, 62B), and a terminal portion of the battery (62A, 62B) stored in the battery case (42). And a case-side connection terminal (43) connected to the battery storage device of the vehicle, the case-side connection terminal (43) being in contact with the terminal portion (41) of the battery (62A, 62B) A terminal displacement mechanism (45) for displacing between a connection position (P1) to be connected and a retracted position (P2) separated from the connection position (P1) is provided, and the case-side connection terminal (43) comprises a plurality of The terminal pins (140, 141) are arranged side by side in a row, and a high voltage terminal pin (140) of the plurality of terminal pins (140, 141) is a plurality of the terminal pins (14). , 141), and the power cable (142) is connected to the high voltage terminal pin (140), and the connection state is maintained by the fixing means (146). It features.
　上記の構成により、バッテリ（６２Ａ，６２Ｂ）を車両に搭載する場合には、ケース側接続端子（４３）を予め退避位置に変位させておく。バッテリ（６２Ａ，６２Ｂ）は、この状態において、バッテリケース（４２）内に挿入する。こうしてバッテリ（６２Ａ，６２Ｂ）がバッテリケース（４２）の内部に挿入されたところで、ケース側接続端子（４３）が接続位置（Ｐ１）まで変位するように端子変位機構（４５）を操作する。この結果、ケース側接続端子（４３）が接続位置（Ｐ１）まで変位し、バッテリケース（４２）に収納されたバッテリ（６２Ａ，６２Ｂ）の端子部（４１）にケース側接続端子（４３）が接触接続される。バッテリ（６２Ａ，６２Ｂ）をバッテリケース（４２）に挿入する際には、バッテリ（６２Ａ，６２Ｂ）の端子部（４１）がケース側接続端子（４３）に直接接触しないため、作業者のバッテリ（６２Ａ，６２Ｂ）の挿入挙動等に拘わらず、バッテリ（６２Ａ，６２Ｂ）の端子部（４１）やケース側接続端子（４３）に大きな負荷が作用するのを回避することができる。
　また、ケース側接続端子（４３）の高圧の端子ピン（１４０）は、複数の端子ピン（１４０，１４１）の並び方向の端部で電力ケーブル（１４２）に接続され、その接続状態が固定手段（１４６）によって維持されている。このため、ケース側接続端子（４３）が端子変位機構（４５）によって昇降操作されても、電力ケーブル（１４２）の接続状態が安定して維持される。また、高圧の端子ピン（１４０）は、複数の端子ピン（１４０，１４１）の並び方向の端部に配置されているため、固定手段（１４６）による固定作業を容易に行うことができる。 With the above configuration, when the battery (62A, 62B) is mounted on a vehicle, the case side connection terminal (43) is displaced in advance to the retracted position. The batteries (62A, 62B) are inserted into the battery case (42) in this state. Thus, when the battery (62A, 62B) is inserted into the battery case (42), the terminal displacement mechanism (45) is operated so that the case side connection terminal (43) is displaced to the connection position (P1). As a result, the case side connection terminal (43) is displaced to the connection position (P1), and the case side connection terminal (43) is attached to the terminal portion (41) of the battery (62A, 62B) housed in the battery case (42). Contact connected. When inserting the battery (62A, 62B) into the battery case (42), the terminal portion (41) of the battery (62A, 62B) does not directly contact the case-side connection terminal (43). Regardless of the insertion behavior or the like of 62A, 62B), it is possible to avoid that a large load acts on the terminal portion (41) of the battery (62A, 62B) and the case side connection terminal (43).
In addition, the high-voltage terminal pin (140) of the case-side connection terminal (43) is connected to the power cable (142) at the end in the direction in which the plurality of terminal pins (140, 141) are arranged. Maintained by (146). Therefore, even if the case-side connection terminal (43) is moved up and down by the terminal displacement mechanism (45), the connection state of the power cable (142) is stably maintained. Further, since the high-voltage terminal pin (140) is disposed at the end in the direction in which the plurality of terminal pins (140, 141) are arranged, the fixing operation by the fixing means (146) can be easily performed.
　本発明の一形態の車両のバッテリ収納装置は、前記固定手段（１４６）の外側には遮蔽部（１５４）が配置されている。 In a battery storage device of a vehicle according to one aspect of the present invention, a shielding portion (154) is disposed outside the fixing means (146).
　この場合、固定手段（１４６）の外側が遮蔽部（１５４）によって覆われているため、悪戯や不注意等によって外部から固定手段（１４６）に触れるのを防ぐことができる。 In this case, since the outside of the fixing means (146) is covered by the shielding part (154), it is possible to prevent touching the fixing means (146) from the outside by mischief or carelessness.
　本発明の一形態の車両のバッテリ収納装置は、前記固定手段は、前記端子ピン（１４０，１４１）の並び方向の外側から締め込まれるボルト（１４６）によって構成され、前記ボルト（１４６）の締め込み方向の外側に前記遮蔽部（１５４）が配置されている。 In the battery storage device of a vehicle according to one aspect of the present invention, the fixing means is constituted by a bolt (146) tightened from the outside in the line direction of the terminal pins (140, 141), and tightening of the bolt (146) The shielding portion (154) is disposed on the outer side in the insertion direction.
　この場合、ボルト（１４６）の締め込み方向の外側に遮蔽部（１５４）が設けられているため、悪戯や不注意等によってドライバー等の工具がボルト（１４６）に接触するのを防止することができる。 In this case, since the shielding portion (154) is provided outside the tightening direction of the bolt (146), it is possible to prevent a tool such as a driver from contacting the bolt (146) due to mischief or carelessness it can.
　本発明の一形態の車両のバッテリ収納装置は、前記端子変位機構（４５）は、前記ケース側接続端子（４３）を保持して昇降する端子保持部材（１４９）を有し、前記遮蔽部（１５４）は、前記端子保持部材（１４９）に一体に設けられている。 In the battery storage device of a vehicle according to one aspect of the present invention, the terminal displacement mechanism (45) has a terminal holding member (149) that holds the case-side connection terminal (43) and ascends and descends; 154) is integrally provided to the terminal holding member (149).
　この場合、端子変位機構（４５）の操作によってケース側接続端子（４３）が端子保持部材（１４９）とともに昇降する際に、遮蔽部（１５４）も端子保持部材（１４９）と一体に昇降する。このため、ケース側接続端子（４３）が退避位置（Ｐ２）と接続位置（Ｐ１）のいずれの位置に停止したときにも、遮蔽部（１５４）によって固定手段（１４６）の外側を同様に覆うことができる。 In this case, when the case-side connection terminal (43) moves up and down together with the terminal holding member (149) by the operation of the terminal displacement mechanism (45), the shielding portion (154) also moves up and down integrally with the terminal holding member (149). Therefore, when the case-side connection terminal (43) is stopped at either the retracted position (P2) or the connected position (P1), the shielding portion (154) similarly covers the outside of the fixing means (146). be able to.

A plurality of cables including the power cable (142) connected to the pins (140, 141) is supported by a cable support bracket (201) integrally provided on the terminal holding member (149).
　この場合、ケース側接続端子（４３）の端子ピン（１４０，１４１）に接続されるケーブルがケーブル支持ブラケット（２０１）を介して端子保持部材（１４９）に支持されるため、端子保持部材（１４９）が昇降操作されるときには、ケーブルがケース側接続端子（４３）と一体に昇降する。このため、この態様を採用した場合には、ケーブルとケース側接続端子（４３）の接続部に負荷が作用しにくくなる。 In this case, the cable connected to the terminal pins (140, 141) of the case-side connection terminal (43) is supported by the terminal holding member (149) through the cable support bracket (201). The cable is moved up and down integrally with the case-side connection terminal (43). For this reason, when this aspect is adopted, a load hardly acts on the connection portion between the cable and the case side connection terminal (43).
　本発明の一形態の車両のバッテリ収納装置は、ケーブル支持ブラケット（２０１）は、前記電力ケーブル（１４２）と前記高圧の端子ピン（１４０）の接続部と上下方向で一部重なりつつ、前記接続部よりも下方に延びている。 In the battery storage device of a vehicle according to one aspect of the present invention, the cable support bracket (201) is partially overlapped in the vertical direction with the connection portion of the power cable (142) and the high voltage terminal pin (140).

　また、ケーブル支持ブラケット２０１は、板状部の一側方でクランプ装置２０２と電力ケーブル１４２等のケーブル類が保持されているが、ケーブル支持ブラケット２０１のケーブル類の配置される側の外周コーナー部分には面取りが施されている。これにより、ケーブル類がケーブル支持ブラケット２０１の外周コーナー部分に接触することがあってもケーブル類に作用する負荷を軽減することができる。 Further, the cable support bracket 201 extends downward below the connecting portion while partially overlapping the connecting portion of the power cable 142 and the high voltage terminal pin 140 in the vertical direction.
Further, in the cable support bracket 201, cables such as the clamp device 202 and the power cable 142 are held on one side of the plate-like portion, but the outer peripheral corner portion of the cable support bracket 201 on the side where the cables are arranged. Is chamfered. Thereby, even if the cables and the like come into contact with the outer peripheral corner portion of the cable support bracket 201, it is possible to reduce the load acting on the cables and the like.
　端子支持ブロック１３９のケース側接続端子４３よりも車幅方向外側位置には、ケース側ガイド部である一対のガイド突起１４７が上方に向かって突設されている。ガイド突起１４７は、全体が略円柱状に形成され、その先端部に球面状の湾曲面、若しくは、先細り状のテーパ面が設けられている。左右の各ガイド突起１４７は、ケース側接続端子４３の高圧端子ピン１４０や信号端子ピン１４１の上端部よりも上方に突出している。 A pair of guide projections 147, which are case-side guide portions, project upward at a position outside the case-side connection terminal 43 of the terminal support block 139 in the vehicle width direction. The entire guide projection 147 is formed in a substantially cylindrical shape, and a spherical curved surface or a tapered tapered surface is provided at the tip thereof. The left and right guide protrusions 147 project upward from the upper end portions of the high voltage terminal pin 140 of the case-side connection terminal 43 and the signal terminal pin 141.
　一方、樹脂ケース部１３２Ｆ（１３２Ｒ）に収納されるバッテリ６２Ａ（６２Ｂ）の下面には、端子支持ブロック１３９側の左右のガイド突起１４７を受容可能な一対のガイド穴１４８が設けられている。ガイド穴１４８は、バッテリ側ガイド部を構成している。ここで、バッテリ６２Ａ（６２Ｂ）が樹脂ケース部１３２Ｆ（１３２Ｒ）内に収納された状態で、ケース側接続端子４３が接続位置Ｐ１（図１７，図２５，図２６参照）に向かって上昇すると、ケース側接続端子４３がバッテリ６２Ａ（６２Ｂ）の端子部４１に接触接続する前に、ガイド突起１４７がガイド穴１４８に挿入される。本実施形態の場合、ガイド突起１４７は、ケース側接続端子４３が退避位置Ｐ２にあるときに、ガイド突起１４７とガイド穴１４８の当接部の離間距離Ｌ１が、ケース側接続端子４３とバッテリ６２Ａ（６２Ｂ）の端子部４１の離間距離Ｌ２よりも短くなるように設定されている。図１７に示すように、ガイド突起１４７のバッテリ方向のガイド端である当該ガイド突起１４７の上端１４７ｅは、ケース側接続端子４３のバッテリ方向の端子端である高圧端子ピン１４０の上端１４０ｅよりも上方側（バッテリ側）に形成されている。 On the other hand, on the lower surface of the battery 62A (62B) housed in the resin case portion 132F (132R), a pair of guide holes 148 capable of receiving the left and right guide protrusions 147 on the terminal support block 139 side are provided. The guide hole 148 constitutes a battery side guide portion. Here, when the case-side connection terminal 43 ascends toward the connection position P1 (see FIGS. 17, 25 and 26) with the battery 62A (62B) housed in the resin case portion 132F (132R), The guide protrusion 147 is inserted into the guide hole 148 before the case-side connection terminal 43 contacts and connects with the terminal portion 41 of the battery 62A (62B). In the case of the present embodiment, when the case-side connection terminal 43 is at the retracted position P2, the guide protrusion 147 is separated by the distance L1 between the guide protrusion 147 and the contact portion of the guide hole 148 with the case-side connection terminal 43 and the battery 62A. It is set to be shorter than the separation distance L2 of the terminal portion 41 of (62B). As shown in FIG. 17, the upper end 147 e of the guide protrusion 147 which is the guide end in the battery direction of the guide protrusion 147 is higher than the upper end 140 e of the high voltage terminal pin 140 which is the terminal end of the case connection terminal 43 in the battery direction. It is formed on the side (battery side).
　端子変位機構４５は、端子支持ブロック１３９を介してケース側接続端子４３を保持する端子保持部材１４９を備えている。端子保持部材１４９は、金属製の板材から成り、車幅方向に沿って延出するベース壁１４９ａと、ベース壁１４９ａの車幅方向の両端部から上方側に屈曲して延出する左右一対の連結壁１４９ｂと、を有している。ベース壁１４９ａの車幅方向の中央領域には、長孔状の挿通孔１５０が形成されている。ベース壁１４９ａの下面側には、連結ピン１５１と、スプリングユニット１５２を介して端子支持ブロック１３９が保持されている。ベース壁１４９ａに保持された端子支持ブロック１３９の一部とケース側接続端子４３は、挿通孔１５０を通してベース壁１４９ａの上方側に突出している。 The terminal displacement mechanism 45 includes a terminal holding member 149 that holds the case-side connection terminal 43 via the terminal support block 139. The terminal holding member 149 is made of a metal plate material, and a pair of left and right portions bent and extended upward from both end portions in the vehicle width direction of the base wall 149a extending in the vehicle width direction and the base wall 149a. And a connecting wall 149b. An elongated through hole 150 is formed in a central region in the vehicle width direction of the base wall 149a. The terminal support block 139 is held on the lower surface side of the base wall 149 a via the connection pin 151 and the spring unit 152. A part of the terminal support block 139 held by the base wall 149 a and the case-side connection terminal 43 protrude upward through the insertion hole 150 to the upper side of the base wall 149 a.
　端子支持ブロック１３９の車幅方向の両縁部には、連結ピン１５１が挿通される挿通孔１５３が形成されている。挿通孔１５３の内径は、連結ピン１５１の外径よりも大きく形成されている。端子支持ブロック１３９は、挿通孔１５３と連結ピン１５１の隙間の範囲で略水平方向（端子部４１に対する接続方向と交差する方向）に変位可能とされている。したがって、端子支持ブロック１３９に支持されたケース側接続端子４３は、端子部４１に対する接続方向と交差する方向に相対変位可能に端子保持部材１４９に保持されている。 Insertion holes 153 into which the connection pins 151 are inserted are formed at both edges of the terminal support block 139 in the vehicle width direction. The inner diameter of the insertion hole 153 is formed larger than the outer diameter of the connection pin 151. The terminal support block 139 is displaceable in a substantially horizontal direction (direction intersecting with the connection direction to the terminal portion 41) in the range of the gap between the insertion hole 153 and the connection pin 151. Therefore, the case-side connection terminal 43 supported by the terminal support block 139 is held by the terminal holding member 149 so as to be relatively displaceable in the direction intersecting the connection direction with respect to the terminal portion 41.
　連結ピン１５１は、端子保持部材１４９のベース壁１４９ａに設けられた支持孔１９８に摺動自在に挿入されている。連結ピン１５１の上端部には抜け止めフランジ１５１ａが一体に設けられている。連結ピン１５１は、抜け止めフランジ１５１ａがベース壁１４９ａの上面に当接することによってベース壁１４９ａに対して抜け止めされる。 The connection pin 151 is slidably inserted into a support hole 198 provided in the base wall 149 a of the terminal holding member 149. A retaining flange 151 a is integrally provided at the upper end portion of the connection pin 151. The connecting pin 151 is prevented from coming off with respect to the base wall 149a by the abutment of the retaining flange 151a with the upper surface of the base wall 149a.
　スプリングユニット１５２は、有底円筒状の金属製のユニットケース１５４と、ユニットケース１５４の開口端に当接可能な円板状のストッパプレート１５５と、ユニットケース１５４の内側底面とストッパプレート１５５の間に介装される弾性部材であるコイルスプリング１５６と、を有している。スプリングユニット１５２は、ユニットケース１５４の外側底面をベース壁１４９ａの下面に当接させた状態でベース壁１４９ａの下方に配置されている。連結ピン１５１は、ユニットケース１５４の底壁を貫通してユニットケース１５４の下方でストッパプレート１５５に結合されている。また、コイルスプリング１５６は、連結ピン１５１の周域に配置されている。 The spring unit 152 has a cylindrical metal unit case 154 with a bottom, a disc-like stopper plate 155 that can abut the opening end of the unit case 154, and an inner bottom surface of the unit case 154 and the stopper plate 155. And a coil spring 156 which is an elastic member interposed therebetween. The spring unit 152 is disposed below the base wall 149a in a state where the outer bottom surface of the unit case 154 is in contact with the lower surface of the base wall 149a. The connection pin 151 penetrates the bottom wall of the unit case 154 and is coupled to the stopper plate 155 below the unit case 154. Further, the coil spring 156 is disposed in the circumferential area of the connection pin 151.
　ケース側接続端子４３と端子支持ブロック１３９は、スプリングユニット１５２と連結ピン１５１を介して端子保持部材１４９に吊り下げ支持されている。ユニットケース１５４とストッパプレート１５５は、ケース側接続端子４３に上方から所定以上の押圧荷重が入力されるまでは離反状態に維持されている。この状態からケース側接続端子４３に所定以上の押圧荷重が入力されると、端子支持ブロック１３９がコイルスプリング１５６を圧縮変位させつつ、端子保持部材１４９に対して下方に相対変位する。こうして、端子支持ブロック１３９が端子保持部材１４９に対して所定量以上相対変位すると、ストッパプレート１５５がユニットケース１５４に当接し、それによって端子保持部材１４９に対する端子支持ブロック１３９（ケース側接続端子４３）の相対変位が規制される（図２６参照）。
　なお、スプリングユニット１５２のユニットケース１５４は、電力ケーブル１４２を高圧端子ピン１４０に締結固定するボルト１４６の頭部の車幅方向外側（ボルト１４６の締め込み方向の外側）に配置されている。本実施形態の場合、ユニットケース１５４は、固定部であるボルト１４６の外側に配置される遮蔽部を構成している。 The case-side connection terminal 43 and the terminal support block 139 are suspended and supported by the terminal holding member 149 via the spring unit 152 and the connection pin 151. The unit case 154 and the stopper plate 155 are maintained in the separated state until a predetermined or more pressing load is input to the case side connection terminal 43 from the upper side. In this state, when a predetermined pressure load is input to the case-side connection terminal 43, the terminal support block 139 is displaced downward relative to the terminal holding member 149 while the coil spring 156 is compressed and displaced. Thus, when the terminal support block 139 is displaced relative to the terminal holding member 149 by a predetermined amount or more, the stopper plate 155 abuts against the unit case 154, whereby the terminal support block 139 (case side connection terminal 43) for the terminal holding member 149 Relative displacement is regulated (see FIG. 26).
The unit case 154 of the spring unit 152 is disposed outside the head of the bolt 146 for fastening and fixing the power cable 142 to the high voltage terminal pin 140 in the vehicle width direction (outside in the tightening direction of the bolt 146). In the case of the present embodiment, the unit case 154 constitutes a shielding portion which is disposed outside the bolt 146 which is a fixing portion.
　また、図面においては省力されているが、端子変位機構４５の周域の一部は不導電性のゴムや樹脂から成るカバー部材によって覆われている。このように端子変位機構４５の周域がカバー部材によって覆われることにより、ボルト１４６を含むケース側接続端子４３の設置部が外部から見え難くなり、ボルトに対するアクセスもしにくくなる。 Further, although the power is saved in the drawing, a part of the peripheral area of the terminal displacement mechanism 45 is covered by a cover member made of nonconductive rubber or resin. By covering the peripheral area of the terminal displacement mechanism 45 with the cover member as described above, the installation portion of the case-side connection terminal 43 including the bolt 146 becomes difficult to see from the outside, and access to the bolt becomes difficult.
　端子保持部材１４９の左右の各連結壁１４９ｂは、樹脂ケース部１３２Ｆ（１３２Ｒ）の側部外側の下部領域において、金属製のリンクプレート１５７の下端に回動自在に保持されている。リンクプレート１５７は、略上下方向に沿って延在する一方向に長いプレート部材である。左右の各リンクプレート１５７の上端部は、操作部材である操作レバー４４の左右のレバー片４４ａの先端に回動可能に連結されている。左右のレバー片４４ａの延出方向の中間領域は、バッテリ支持フレーム１１０に取り付けられた左右の各支持ステー１３５に回動可能に枢支されている。左右の各リンクプレート１５７は、操作レバー４４が一方向（図１４，図１６中の時計回り方向）に回動操作されることにより、上方側に引き上げられ、それによって端子保持部材１４９の左右の各連結壁１４９ｂを上方側に変位させる。このとき、端子保持部材１４９に保持されたケース側接続端子４３が退避位置Ｐ２から接続位置Ｐ１へと変位する。
　なお、図１４，図１６中の符号１９７は、左右の支持ステー１３５の下端近傍に取り付けられて、樹脂ケース部１３２Ｆ（１３２Ｒ）の周域を補強する補強フレームである。 The left and right connecting walls 149b of the terminal holding member 149 are rotatably held at the lower end of the metal link plate 157 in the lower region outside the side of the resin case portion 132F (132R). The link plate 157 is a plate member elongated in one direction extending substantially in the vertical direction. The upper end portions of the left and right link plates 157 are rotatably connected to the tips of left and right lever pieces 44 a of the operation lever 44 which is an operation member. A middle region in the extending direction of the left and right lever pieces 44 a is pivotally supported by the left and right support stays 135 attached to the battery support frame 110. The left and right link plates 157 are pulled upward by turning the operation lever 44 in one direction (clockwise direction in FIGS. 14 and 16), whereby the left and right sides of the terminal holding member 149 are moved. Each connecting wall 149b is displaced upward. At this time, the case-side connection terminal 43 held by the terminal holding member 149 is displaced from the retracted position P2 to the connection position P1.
In addition, the code | symbol 197 in FIG. 14, FIG. 16 is a reinforcement frame which is attached to lower end vicinity of the support stay 135 on either side, and reinforces the circumferential area of resin case part 132F (132R).
　左右の各リンクプレート１５７の下端と端子保持部材１４９の左右の連結壁１４９ｂとは、図１７に示すように、回動ピン１５８が長孔１５９に挿入されて連係されている。回動ピン１５８は、左右の各連結壁１４９ｂに支持され、長孔１５９は、リンクプレート１５７に形成されている。このため、操作レバー４４による操作によって、リンクプレート１５７が上方に引き上げられるときには、図１７（Ｂ）の（Ｉ），（ＩＩ）に示すように、リンクプレート１５７の所定のストローク分だけ回動ピン１５８が長孔１５９内を遊動する。その結果、端子保持部材１４９は、操作レバー４４の操作の開始に対して、上方変位を開始するタイミングが遅くなる。
　なお、図１７（Ｂ）は、図１７（Ａ）のＥ部の動作状態を示した図である。 The lower ends of the left and right link plates 157 and the left and right connection walls 149b of the terminal holding member 149 are linked with each other by inserting a pivot pin 158 into the long hole 159, as shown in FIG. The pivot pin 158 is supported by the left and right connection walls 149 b, and the long holes 159 are formed in the link plate 157. Therefore, when the link plate 157 is pulled upward by the operation of the operation lever 44, as shown in (I) and (II) of FIG. 17B, the pivot pin is moved by a predetermined stroke of the link plate 157. 158 floats in the long hole 159. As a result, with respect to the start of the operation of the operation lever 44, the timing at which the terminal holding member 149 starts the upward displacement is delayed.
FIG. 17B is a diagram showing an operation state of a portion E of FIG. 17A.
　また、バッテリ６２Ａ（６２Ｂ）をバッテリケース４２に固定するためのロック機構１３３は、可動ブロック１６０を備えている。可動ブロック１６０は、バッテリケース４２の左右の支持ステー１３５の上端部に回動可能（変位可能）に取り付けられている。可動ブロック１６０は、操作レバー４４が初期位置から所定位置範囲に回動するときに、操作レバー４４から操作力を受けてバッテリケース４２の上面方向に回動する。可動ブロック１６０は、バッテリ６２Ａ（６２Ｂ）の上面に押し付けられ、バッテリ６２Ａ（６２Ｂ）の抜け方向の変位を規制する。 The lock mechanism 133 for fixing the battery 62A (62B) to the battery case 42 includes a movable block 160. The movable block 160 is rotatably (displaceably) attached to the upper end portions of the left and right support stays 135 of the battery case 42. When the operating lever 44 pivots from the initial position to the predetermined position range, the movable block 160 pivots in the upper surface direction of the battery case 42 by receiving an operating force from the operating lever 44. The movable block 160 is pressed against the upper surface of the battery 62A (62B), and regulates displacement of the battery 62A (62B) in the removal direction.
　図１９は、操作レバー４４と可動ブロック１６０を左側の支持ステー１３５の上部右前方から見た図である。
　操作レバー４４は、第１回動軸１６２を中心として支持ステー１３５に回動可能に支持されている。第１回動軸１６２は、支持ステー１３５の上下方向の略中央の前部寄り部分に軸支された軸であり、車両の車幅方向に沿って配置されている。なお、一部の図では、第１回動軸１６２の軸心ｏ１のみが示されている。 FIG. 19 is a view of the operation lever 44 and the movable block 160 as viewed from the upper right front of the support stay 135 on the left side.
The operation lever 44 is rotatably supported by the support stay 135 about the first rotation shaft 162. The first pivoting shaft 162 is a shaft pivotally supported at a front center portion of the support stay 135 substantially in the vertical direction, and is disposed along the vehicle width direction of the vehicle. In some of the drawings, only the axial center o1 of the first rotation shaft 162 is shown.
　ロック機構１３３の可動ブロック１６０は、第１回動軸１６２と直交する第２回動軸１６３を中心として支持ステー１３５に回動可能に支持されている。第２回動軸１６３は、支持ステー１３５の上端部に軸支された軸であり、車両の前後方向に沿って配置されている。 The movable block 160 of the lock mechanism 133 is rotatably supported by the support stay 135 about a second rotation shaft 163 orthogonal to the first rotation shaft 162. The second pivot shaft 163 is a shaft pivotally supported by the upper end portion of the support stay 135, and is disposed along the longitudinal direction of the vehicle.
　本実施形態の場合、第１回動軸１６２は、第１回動軸１６２の軸線ｏ１が樹脂ケース部１３２Ｆ（１３２Ｒ）に収納されたバッテリ６２Ａ（６２Ｂ）と重なるように配置されている（図２０（ｃ），図２２（ｃ），図２４（ｃ）等参照）。また、第２回動軸１６３は、第２回動軸１６３の軸線ｏ２が樹脂ケース部１３２Ｆ（１３２Ｒ）に収納されたバッテリ６２Ａ（６２Ｂ）の外側に位置されるように配置されている（図２０（ｃ），図２２（ｃ），図２４（ｃ）等参照）。 In the case of the present embodiment, the first pivoting shaft 162 is arranged such that the axis o1 of the first pivoting shaft 162 overlaps the battery 62A (62B) accommodated in the resin case portion 132F (132R) (see FIG. 20 (c), FIG. 22 (c), FIG. 24 (c) etc.). In addition, the second pivoting shaft 163 is disposed so that the axis o2 of the second pivoting shaft 163 is located outside the battery 62A (62B) housed in the resin case portion 132F (132R) (see FIG. 20 (c), FIG. 22 (c), FIG. 24 (c) etc.).
　操作レバー４４は、車幅方向に沿って延出する操作片４４ｂと、操作片４４ｂの両端部から略直交方向に屈曲して延びる左右のレバー片４４ａと、を有している。左右のレバー片４４ａの延出方向の中間領域は、第１回動軸１６２によって左右の支持ステー１３５に支持されている。左右のレバー片４４ａは、側面視が略Ｌ字状（先端部が前方に突出する略Ｌ字状）に屈曲して形成されている。以下、レバー片４４ａの屈曲部を挟んで操作片４４ｂ側を第１延出部４４ａ－１と呼び、屈曲部を挟んで操作片４４ｂと逆側を第２延出片４４ａ－２と呼ぶものとする。左右のレバー片４４ａは、第２延出片４４ａ－２の延出方向の略中間位置が第１回動軸１６２を介して支持ステー１３５に支持されている。リンクプレート１５７の上端部は、第２延出片４４ａ－２の先端部に連結ピン１６４を介して回動可能に連結されている。 The operation lever 44 has an operation piece 44b extending along the vehicle width direction, and left and right lever pieces 44a bent and extended in substantially orthogonal directions from both end portions of the operation piece 44b. An intermediate region in the extending direction of the left and right lever pieces 44 a is supported by the first and second support stays 135 by the first pivot shaft 162. The left and right lever pieces 44a are formed to be bent in a substantially L shape in a side view (a substantially L shape in which the tip portion protrudes forward). Hereinafter, the side of the operation piece 44b is referred to as a first extending part 44a-1 with the bent portion of the lever piece 44a interposed therebetween, and the side opposite to the operation piece 44b is referred to as a second extending segment 44a-2 with the bent portion interposed therebetween. I assume. The left and right lever pieces 44a are supported by the support stay 135 at a substantially intermediate position in the extension direction of the second extending piece 44a-2 via the first pivot shaft 162. The upper end portion of the link plate 157 is rotatably connected to the tip end portion of the second extending piece 44a-2 via a connection pin 164.
　ここで、ロック機構１３３の可動ブロック１６０は、図１９に示すように、枢支部１６０ａと、変位規制壁１６０ｂ（バッテリ規制部）と、弾性体ブロック１６０ｃ（バッテリ規制部）と、保持力受壁１６０ｄ（保持力受部）と、カム壁１６０ｅと、を有している。枢支部１６０ａは、第２回動軸１６３に回動可能に支持されている。変位規制壁１６０ｂは、枢支部１６０ａに連設されて、樹脂ケース部１３２Ｆ（１３２Ｒ）の内側領域に変位したときに、バッテリ６２Ａ（６２Ｂ）の浮き上がり方向の変位を規制可能とされている。弾性体ブロック１６０ｃは、変位規制壁１６０ｂの一面に取り付けられ、変位規制壁１６０ｂがバッテリ６２Ａ（６２Ｂ）の浮き上がり方向の変位を規制するときに、バッテリ６２Ａの上面に直接当接する。このとき、弾性体ブロック１６０ｃは弾性変形し、弾発力をバッテリ６２Ａの上面に作用させる。 Here, as shown in FIG. 19, the movable block 160 of the lock mechanism 133 has a pivot 160a, a displacement restricting wall 160b (battery restricting portion), an elastic block 160c (battery restricting portion), and a holding force receiving wall 160 d (holding force receiving portion) and a cam wall 160 e. The pivot portion 160 a is rotatably supported by the second pivot shaft 163. The displacement restricting wall 160b is connected to the pivot portion 160a, and when it is displaced to the inner region of the resin case portion 132F (132R), the displacement of the battery 62A (62B) in the floating direction can be restricted. The elastic block 160c is attached to one surface of the displacement regulating wall 160b, and directly abuts on the upper surface of the battery 62A when the displacement regulating wall 160b regulates the displacement of the battery 62A (62B) in the floating direction. At this time, the elastic block 160c is elastically deformed to cause the elastic force to act on the upper surface of the battery 62A.
　可動ブロック１６０の変位規制壁１６０ｂと弾性体ブロック１６０ｃ（バッテリ規制部）は、樹脂ケース部１３２Ｆ（１３２Ｒ）に対するバッテリ６２Ａ，６２Ｂの挿入方向視において、バッテリ非固定状態でバッテリ６２Ａ，６２Ｂの外側に位置され（図２０（ｃ）参照）、かつ、バッテリ固定状態でバッテリ６２Ａ，６２Ｂと重なる（図２２（ｃ），図２４（ｃ）参照）ように構成されている。 The displacement restricting wall 160b of the movable block 160 and the elastic block 160c (battery restricting portion) are outside the batteries 62A and 62B in the battery unfixed state as viewed from the insertion direction of the batteries 62A and 62B with respect to the resin case portion 132F (132R). It is configured to be positioned (see FIG. 20 (c)) and to overlap with the batteries 62A and 62B in the battery fixed state (see FIGS. 22 (c) and 24 (c)).
　保持力受壁１６０ｄは、枢支部１６０ａに連設され、第２回動軸１６３回りについて、変位規制壁１６０ｂと略直角となる方向に延びている。保持力受壁１６０ｄは、操作レバー４４のレバー片４４ａから保持荷重を受け、変位規制壁１６０ｂと弾性体ブロック１６０ｃがバッテリ６２Ａ（６２Ｂ）の浮き上がり方向の変位を規制する状態を維持する。カム壁１６０ｅは、変位規制壁１６０ｂと保持力受壁１６０ｄの前部側で両者を接続する壁であり、変位規制壁１６０ｂ側から保持力受壁１６０ｄの裏面１６０ｄ－１（保持力受面）方向に向かって滑らかに連続するカム面１６０ｅ－１を有している。 The holding force receiving wall 160d is provided continuously with the pivot portion 160a, and extends around the second rotation shaft 163 in a direction substantially perpendicular to the displacement control wall 160b. The holding force receiving wall 160d receives a holding load from the lever piece 44a of the operation lever 44, and maintains the state in which the displacement regulating wall 160b and the elastic block 160c regulate the displacement of the battery 62A (62B) in the floating direction. The cam wall 160e is a wall connecting the displacement restricting wall 160b and the holding force receiving wall 160d on the front side, and the back surface 160d-1 (holding force receiving surface) of the holding force receiving wall 160d from the displacement restricting wall 160b side It has a cam surface 160e-1 smoothly continuous in the direction.
　本実施形態の場合、保持力受壁１６０ｄ（保持力受部）は、第１回動軸１６２に沿う方向視において、バッテリ固定状態で操作レバー４４のレバー片４４ａと重なるように構成されている（図１９参照）。 In the case of the present embodiment, the holding force receiving wall 160 d (holding force receiving portion) is configured to overlap the lever piece 44 a of the operation lever 44 in the battery fixed state in a direction view along the first pivot shaft 162 (See Figure 19).
　ロック機構１３３の可動ブロック１６０は、操作レバー４４の回動操作に応じて変位規制壁１６０ｂと弾性体ブロック１６０ｃが上方に跳ね上がったロック解除位置と、変位規制壁１６０ｂと弾性体ブロック１６０ｃが樹脂ケース部１３２Ｆ（１３２Ｒ）の内側方向にほぼ９０°倒れ込んだロック位置と、の間で回動可能とされている。ロック機構１３３は、変位規制壁１６０ｂと弾性体ブロック１６０ｃがロック解除位置にあるときにバッテリ非固定状態となり、変位規制壁１６０ｂと弾性体ブロック１６０ｃがロック位置にあるときにバッテリ固定状態となる。なお、各可動ブロック１６０は、図示しないスプリングによって常時跳ね上げ方向に付勢されている。 The movable block 160 of the lock mechanism 133 has a lock release position in which the displacement restricting wall 160b and the elastic block 160c jump upward in response to the turning operation of the operation lever 44, and the displacement restricting wall 160b and the elastic block 160c are resin cases. It can be pivoted between the lock position in which the part 132F (132R) is inclined by approximately 90 degrees inward. The lock mechanism 133 is in the battery non-fixing state when the displacement restricting wall 160b and the elastic block 160c are in the unlocking position, and is in the battery fixing state when the displacement restricting wall 160b and the elastic block 160c are in the locking position. In addition, each movable block 160 is always urged | biased in the springing direction by the spring which is not shown in figure.
　バッテリ非固定状態のときには、操作レバー４４は最大に前方に倒され、このとき操作レバー４４の操作片４４ｂは樹脂ケース部１３２Ｆ（１３２Ｒ）の挿脱口１３６（内壁）よりも前方側に変位している。このときの操作レバー４４の位置を初期位置と呼ぶものとする。また、バッテリ固定状態のときには、操作レバー４４は後部上方側に引き起こされ、このとき操作レバー４４の操作片４４ｂは樹脂ケース部１３２Ｆ（１３２Ｒ）の挿脱口１３６の上方位置に変位している。 When the battery is not fixed, the operation lever 44 is turned forward to the maximum, and at this time, the operation piece 44b of the operation lever 44 is displaced forward of the insertion and removal opening 136 (inner wall) of the resin case portion 132F (132R). There is. The position of the operation lever 44 at this time is referred to as an initial position. Further, in the battery fixed state, the operation lever 44 is raised to the rear upper side, and at this time, the operation piece 44b of the operation lever 44 is displaced to the upper position of the insertion / removal opening 136 of the resin case portion 132F (132R).
　また、操作レバー４４のレバー片４４ａのうちの、第１延出部４４ａ－１には、後方側に膨出するカム突起１６５が形成されている。カム突起１６５は、操作レバー４４が初期位置から、上部後方側に引き起こされるときに、跳ね上げ状態にある可動ブロック１６０のカム面１６０ｅ－１に当接し、そのカム面１６０ｅ－１に摺接しつつ可動ブロック１６０を回動方向に押圧する。可動ブロック１６０は、これにより、ロック解除位置からロック位置に向けて回動操作される。こうして、操作レバー４４の引き起こし操作が進行してカム突起１６５の接触部がカム面１６０ｅ－１の終端位置に達すると、レバー片４４ａの内側面（車幅方向内側に向く面）が可動ブロック１６０の保持力受壁１６０ｄの裏面１６０ｄ－１と当接するようになる。この状態は、操作レバー４４が最大引き上げ操作位置に達するまで継続する。 Further, in the first extending portion 44a-1 of the lever piece 44a of the operation lever 44, a cam protrusion 165 which bulges rearward is formed. The cam projection 165 abuts on the cam surface 160e-1 of the movable block 160 in the flipped up state and is in sliding contact with the cam surface 160e-1 when the operation lever 44 is raised from the initial position to the upper rear side. The movable block 160 is pressed in the rotational direction. The movable block 160 is thereby turned from the unlocked position toward the locked position. Thus, when the operation of causing the operation lever 44 progresses and the contact portion of the cam projection 165 reaches the end position of the cam surface 160e-1, the inner side surface (the surface facing inward in the vehicle width direction) of the lever piece 44a is the movable block 160 The holding force receiving wall 160d abuts on the back surface 160d-1. This state continues until the operation lever 44 reaches the maximum pull-up operation position.
　ところで、ロック機構１３３と端子変位機構４５は共通の操作レバー４４によって操作される。そして、ロック機構１３３と端子変位機構４５の各作動状態は操作レバー４４の回動操作位置によって決まる。端子変位機構４５とロック機構１３３とは、操作レバー４４による操作によってロック機構１３３がバッテリ６２Ａ（６２Ｂ）を固定し、その状態で端子変位機構４５がケース側接続端子４３を接続位置Ｐ１に変位させるように相互に連係されている。 The lock mechanism 133 and the terminal displacement mechanism 45 are operated by the common operation lever 44. The operating states of the lock mechanism 133 and the terminal displacement mechanism 45 are determined by the rotational operation position of the operation lever 44. In the terminal displacement mechanism 45 and the lock mechanism 133, the lock mechanism 133 fixes the battery 62A (62B) by the operation of the operation lever 44, and the terminal displacement mechanism 45 displaces the case side connection terminal 43 to the connection position P1 in that state. And so on.
　次に、図２０～図２６を参照して、バッテリ６２Ａ（６２Ｂ）を樹脂ケース部１３２Ｆ（１３２Ｒ）に挿入した後に、バッテリ６２Ａ（６２Ｂ）を樹脂ケース部１３２Ｆ（１３２Ｒ）に固定し、かつ、ケース側接続端子４３をバッテリ６２Ａ（６２Ｂ）の端子部４１に接続する一連の動作について説明する。
　図２０に示す状態は、操作レバー４４が前方に最大に倒れた初期位置にある。このとき、操作レバー４４のレバー片４４ａの先端部は最下方位置に位置され、リンクプレート１５７と、端子変位機構４５の端子保持部材１４９も最下方位置に変位している。バッテリ６２Ａ（６２Ｂ）は、この状態で樹脂ケース部１３２Ｆ（１３２Ｒ）内に挿入されている。このとき、ケース側接続端子４３は、図１７に示すように退避位置Ｐ２に位置している。また、ロック機構１３３の可動ブロック１６０は、上方に跳ね上がったロック解除位置に位置されている。 Next, referring to FIGS. 20 to 26, after battery 62A (62B) is inserted into resin case portion 132F (132R), battery 62A (62B) is fixed to resin case portion 132F (132R), and A series of operations for connecting the case side connection terminal 43 to the terminal portion 41 of the battery 62A (62B) will be described.
In the state shown in FIG. 20, the operating lever 44 is in the initial position at which the operating lever 44 is maximally tilted forward. At this time, the tip of the lever piece 44a of the operation lever 44 is positioned at the lowermost position, and the link plate 157 and the terminal holding member 149 of the terminal displacement mechanism 45 are also displaced to the lowermost position. The battery 62A (62B) is inserted in the resin case portion 132F (132R) in this state. At this time, the case side connection terminal 43 is located at the retracted position P2 as shown in FIG. In addition, the movable block 160 of the lock mechanism 133 is positioned at the lock release position that has jumped upward.
　この状態から操作レバー４４が引き起こし操作されると、図２１に示すように、操作レバー４４のカム突起１６５が可動ブロック１６０のカム面１６０ｅ－１に当接し、そのカム面１６０ｅ－１に摺接しつつ可動ブロック１６０をロック位置方向に回動させる。
　この操作レバー４４の操作開始当初は、リンクプレート１５７がレバー片４４ａによって引き上げられるが、リンクプレート１５７と端子保持部材１４９の間には前述のように長孔１５９による遊びがあるため、このとき端子保持部材１４９の上昇変位の開始は遅れる。 When the operation lever 44 is pulled and operated from this state, as shown in FIG. 21, the cam projection 165 of the operation lever 44 abuts on the cam surface 160e-1 of the movable block 160 and is in sliding contact with the cam surface 160e-1. At the same time, the movable block 160 is pivoted in the lock position direction.
At the beginning of the operation of the operation lever 44, the link plate 157 is pulled up by the lever piece 44a, but there is play due to the long hole 159 between the link plate 157 and the terminal holding member 149 as described above. The start of the upward displacement of the holding member 149 is delayed.
　操作レバー４４の引き起こし操作が進行すると、図２２に示すように、可動ブロック１６０の回動が進んで可動ブロック１６０の弾性体ブロック１６０ｃがバッテリ６２Ａの上面に当接するようになる。このとき、端子変位機構４５の端子保持部材１４９は、リンクプレート１５７を介した操作レバー４４による引き上げによって上方に変位する。また、このとき、図２３に示すように、端子支持ブロック１３９のガイド突起１４７がバッテリ６２Ａ（６２Ｂ）の下面側のガイド穴１４８に嵌入し、それによって端子支持ブロック１３９とケース側接続端子４３の端子接続方向と交差する方向の位置が微調整される。 When the raising operation of the operation lever 44 proceeds, as shown in FIG. 22, the rotation of the movable block 160 proceeds, and the elastic block 160c of the movable block 160 comes in contact with the upper surface of the battery 62A. At this time, the terminal holding member 149 of the terminal displacement mechanism 45 is displaced upward by pulling up by the operation lever 44 via the link plate 157. Further, at this time, as shown in FIG. 23, the guide projection 147 of the terminal support block 139 is fitted into the guide hole 148 on the lower surface side of the battery 62A (62B), whereby the terminal support block 139 and the case side connection terminal 43 are provided. The position in the direction intersecting with the terminal connection direction is finely adjusted.
　さらに操作レバー４４の引き起こし操作が進行すると、図２４に示すように、操作レバー４４のレバー片４４ａが可動ブロック１６０の保持力受壁１６０ｄの裏面側に回り込んで当接するようになる。これにより、可動ブロック１６０の変位規制壁１６０ｂが所定の変位規制位置まで回動し、弾性体ブロック１６０ｃを介してバッテリ６２Ａ（６２Ｂ）の浮き上がり方向の変位を規制するようになる。このとき、図２５に示すように、端子変位機構４５の端子保持部材１４９は、リンクプレート１５７を介した操作レバー４４による引き上げによってさらに上昇し、ケース側接続端子４３が接続位置Ｐ１まで変位する。これにより、ケース側接続端子４３は、バッテリ６２Ａ（６２Ｂ）の端子部４１に嵌合接続される。 When the raising operation of the operation lever 44 further progresses, as shown in FIG. 24, the lever piece 44a of the operation lever 44 comes in contact with the back surface side of the holding force receiving wall 160d of the movable block 160. Thereby, the displacement restricting wall 160b of the movable block 160 is pivoted to a predetermined displacement restricting position, and the displacement of the battery 62A (62B) in the floating direction is restricted via the elastic block 160c. At this time, as shown in FIG. 25, the terminal holding member 149 of the terminal displacement mechanism 45 is further raised by pulling up by the operation lever 44 via the link plate 157, and the case side connection terminal 43 is displaced to the connection position P1. Thus, the case side connection terminal 43 is fitted and connected to the terminal portion 41 of the battery 62A (62B).
　図２４に示す状態から操作レバー４４がさらに引き起こし方向に所定量操作されると、端子変位機構４５では、図２６に示すように端子保持部材１４９がさらに上方に変位する。このとき、スプリングユニット１５２のコイルスプリング１５６が圧縮されて、ケース側接続端子４３がバッテリ６２Ａ（６２Ｂ）の端子部４１に所定荷重で押圧される。これにより、ロック機構１３３によるバッテリ６２Ａ（６２Ｂ）のロックと、端子変位機構４５による端子接続が完了する。
　なお、本実施形態の場合、バッテリ収納装置６４内の任意の箇所には、操作レバー４４が操作完了位置まで操作されたときに、打音等のクリック音を発生して操作者に操作の完了を知らせる機構が設けられている。 When the operation lever 44 is further pulled from the state shown in FIG. 24 and operated in the direction for a predetermined amount, in the terminal displacement mechanism 45, the terminal holding member 149 is further displaced upward as shown in FIG. At this time, the coil spring 156 of the spring unit 152 is compressed, and the case side connection terminal 43 is pressed against the terminal portion 41 of the battery 62A (62B) with a predetermined load. Thereby, the lock of the battery 62A (62B) by the lock mechanism 133 and the terminal connection by the terminal displacement mechanism 45 are completed.
In the case of the present embodiment, when the operation lever 44 is operated to the operation completion position, a click sound such as a tapping sound is generated at an arbitrary position in the battery storage device 64 to complete the operation to the operator A mechanism is provided to
　図２７は、操作レバー４４が操作完了前の状態のときにおけるバッテリ収納装置６４とシート８を示した部分断面側面図である。図２８は、操作レバー４４が操作完了状態のときにおけるバッテリ収納装置６４とシート８を示した部分断面側面図である。
　これらの図に示すように、シート８は、前端部側に車幅方向に沿うヒンジ軸１７０を有し、そのヒンジ軸１７０を中心として車体に回動可能に支持されている。また、シート８の裏面には、前後に離間して一対の突起１７１Ａ，１７１Ｂが設けられている。突起１７１Ａ，１７１Ｂは、シート８の裏面から下方に向かって突出している。一対の突起１７１Ａ，１７１Ｂは、バッテリ収納装置６４の前後の操作レバー４４が操作完了位置まで完全に操作されているときには、図２８に示すように、操作レバー４４に接触することなく各操作レバー４４の前方側の空間に進入するように設けられている。また、一対の突起１７１Ａ，１７１Ｂは、バッテリ収納装置６４の前後の操作レバー４４が操作完了前の状態のときには、図２７に示すように、操作レバー４４の操作片４４ｂの上面に当接するように設定されている。したがって、いずれかの操作レバー４４が操作完了位置まで完全に操作されていないときには、シート８の閉塞が突起１１７Ａや１１７Ｂによって阻害される。このため、操作レバー４４が操作完了位置に達していないことを作業者に知らせることができる。 FIG. 27 is a partial cross-sectional side view showing the battery storage device 64 and the seat 8 when the operation lever 44 is in a state before the operation is completed. FIG. 28 is a partial cross-sectional side view showing the battery storage device 64 and the seat 8 when the operation lever 44 is in the operation completed state.
As shown in these drawings, the seat 8 has a hinge shaft 170 along the vehicle width direction on the front end side, and is rotatably supported by the vehicle body about the hinge shaft 170. Further, on the back surface of the sheet 8, a pair of protrusions 171A and 171B are provided separately from each other in the front and back direction. The protrusions 171A and 171B protrude downward from the back surface of the sheet 8. The pair of projections 171A and 171B are not in contact with the operation lever 44 as shown in FIG. It is provided to enter the space on the front side of the Further, as shown in FIG. 27, the pair of projections 171A and 171B abut on the upper surface of the operation piece 44b of the operation lever 44 when the front and rear operation levers 44 of the battery storage device 64 are in a state before the operation is completed It is set. Therefore, when one of the control levers 44 is not completely operated to the operation completion position, the blocking of the seat 8 is inhibited by the projections 117A and 117B. Therefore, the operator can be notified that the control lever 44 has not reached the operation complete position.
　なお、操作レバー４４の位置によっては、シート８の閉じ操作時に突起１７１Ａ，１７１Ｂが操作レバー４４の操作片４４ｂの上面に当接することにより、操作レバー４４を操作完了位置まで押し込み操作させることもできる。
　また、本実施形態の場合、前後の操作レバー４４が初期位置にあるときには、シート８側の突起１１７Ａ，１１７Ｂが、操作レバー４４の後方側の空間に進入して操作レバー４４と接触しないように設定されている。 Depending on the position of the operating lever 44, the operating lever 44 can be pushed to the operation complete position by bringing the projections 171A and 171B into contact with the upper surface of the operating piece 44b of the operating lever 44 when the seat 8 is closed. .
Further, in the case of the present embodiment, when the front and rear operation levers 44 are in the initial position, the projections 117A and 117B on the seat 8 side do not enter the space on the rear side of the operation lever 44 and do not contact the operation levers 44 It is set.
　以上のように、本実施形態のバッテリ収納装置６４は、バッテリ６２Ａ，６２Ｂをバッテリケース４２（樹脂ケース部１３２Ｆ，１３２Ｒ）に挿入する前に、ケース側接続端子４３を退避位置Ｐ２に位置させておき、バッテリ６２Ａ，６２Ｂの挿入の完了後に、ケース側接続端子４３を接続位置Ｐ１に変位させて、ケース側接続端子４３をバッテリ６２Ａ，６２Ｂの端子部４１に接続することができる。このため、作業者のバッテリ６２Ａ，６２Ｂの挿入挙動等に拘わらず、バッテリ６２Ａ，６２Ｂの端子部４１やケース側接続端子４３に大きな負荷が作用するのを回避することができる。 As described above, in the battery storage device 64 of the present embodiment, the case-side connection terminal 43 is positioned at the retraction position P2 before the batteries 62A and 62B are inserted into the battery case 42 ( resin case portions 132F and 132R). After the insertion of the batteries 62A and 62B is completed, the case-side connection terminal 43 can be displaced to the connection position P1 to connect the case-side connection terminal 43 to the terminal portion 41 of the batteries 62A and 62B. Therefore, regardless of the insertion behavior or the like of the battery 62A, 62B of the worker, it is possible to avoid that a large load acts on the terminal portion 41 of the battery 62A, 62B or the case side connection terminal 43.
　さらに、本実施形態のバッテリ収納装置６４は、高圧端子ピン１４０が、ケース側接続端子４３の端子ピンの並び方向の端部で電力ケーブル１４２に接続され、その接続状態が固定手段であるボルト１４６によって維持されている。このため、操作レバー４４の操作等によってケース側接続端子４３が昇降しても、電力ケーブル１４２の接続状態を安定して維持することができる。また、本実施形態のバッテリ収納装置６４は、高圧端子ピン１４０が、ケース側接続端子４３の端子ピンの並び方向の端部に配置されているため、ボルト１４６による電力ケーブル１４２の固定作業を容易に行うことができる。 Furthermore, in the battery storage device 64 of the present embodiment, the high voltage terminal pin 140 is connected to the power cable 142 at the end of the case pin 43 in the direction in which the terminal pins are lined. Is maintained by Therefore, even if the case-side connection terminal 43 moves up and down by the operation of the operation lever 44 or the like, the connection state of the power cable 142 can be stably maintained. Further, in the battery storage device 64 of the present embodiment, the high voltage terminal pin 140 is disposed at the end of the case-side connection terminal 43 in the direction in which the terminal pins are arranged, so the work of fixing the power cable 142 by the bolt 146 is easy. Can be done.
　また、本実施形態のバッテリ収納装置６４では、電力ケーブル１４２を接続するボルトの車幅方向外側に遮蔽部を兼ねるユニットケース１５４が配置されている。このため、悪戯や不注意等によって外部から固定手段であるボルト１４６に工具等が触れるのを防ぐことができる。
　特に、本実施形態のように、固定手段が、ケース側接続端子４３の端子ピンの並び方向の外側から締め込まれるボルト１４６によって構成されている場合には、悪戯や不注意等によってドライバー等の工具でボルト１４６の頭部が操作され易いが、ドライバー等の工具がボルト１４６の頭部に接触するのをユニットケース１５４によって防ぐことができる。 Further, in the battery storage device 64 of the present embodiment, a unit case 154 which doubles as a shielding portion is disposed on the outer side in the vehicle width direction of the bolt connecting the power cable 142. For this reason, it is possible to prevent a tool or the like from touching the bolt 146 which is the fixing means from the outside due to mischief or carelessness.
In particular, in the case where the fixing means is constituted by the bolt 146 which is tightened from the outside in the direction of arrangement of the terminal pins of the case-side connection terminal 43 as in the present embodiment, The head of the bolt 146 can be easily operated by a tool, but the unit case 154 can prevent the tool such as a driver from coming into contact with the head of the bolt 146.
　さらに、本実施形態のバッテリ収納装置６４では、遮蔽部であるユニットケース１５４が端子変位機構４５の端子保持部材１４９に一体に設けられている。このため、端子変位機構４５の操作によってケース側接続端子４３が端子保持部材１４９と一体に昇降する際に、ユニットケース１５４も端子保持部材１４９と一体に昇降する。したがって、この構成を採用した場合には、ケース側接続端子４３が退避位置Ｐ２と接続位置Ｐ１のいずれの位置に停止したときにも、ユニットケース１５４によってボルト１４６の車幅方向外側部分を同様に覆うことができる。 Furthermore, in the battery storage device 64 of the present embodiment, a unit case 154 which is a shielding portion is provided integrally with the terminal holding member 149 of the terminal displacement mechanism 45. Therefore, when the case-side connection terminal 43 moves up and down integrally with the terminal holding member 149 by the operation of the terminal displacement mechanism 45, the unit case 154 also moves up and down together with the terminal holding member 149. Therefore, when this configuration is adopted, the unit case 154 similarly applies the outer portion of the bolt 146 in the vehicle width direction even when the case side connection terminal 43 is stopped at either the retracted position P2 or the connected position P1. It can be covered.
　また、本実施形態のバッテリ収納装置６４は、電力ケーブル１４２や信号線１４４を支持するケーブル支持ブラケット２０１が端子変位機構４５の端子保持部材１４９に一体に設けられている。このため、端子変位機構４５の操作によってケース側接続端子４３が端子保持部材１４９と一体に昇降する際に、ケーブル支持ブラケット２０１に支持されたケーブル類も一体に昇降する。したがって、この構成を採用した場合には、ケース側接続端子４３が昇降する際に、ケーブル類とケース側接続端子４３の接続部に作用する負荷を軽減することができる。 Further, in the battery storage device 64 of the present embodiment, a cable support bracket 201 for supporting the power cable 142 and the signal line 144 is provided integrally with the terminal holding member 149 of the terminal displacement mechanism 45. Therefore, when the case-side connection terminal 43 moves up and down integrally with the terminal holding member 149 by the operation of the terminal displacement mechanism 45, the cables supported by the cable support bracket 201 also move up and down together. Therefore, when this configuration is adopted, it is possible to reduce the load acting on the connection portion between the cables and the case-side connection terminal 43 when the case-side connection terminal 43 moves up and down.
　また、本実施形態のバッテリ収納装置６４においては、ケーブル支持ブラケット２０１は、電力ケーブル１４２と高圧端子ピン１４０の接続部と上下方向で一部重なりつつ、その接続部よりも下方に延びている。このため、操作レバー４４による操作等によって端子保持部材１４９が下降する際に、電力ケーブル１４２と高圧端子ピン１４０の接続部が周囲の部材と干渉するのを、ケーブル支持ブラケット２０１によって防ぐことができる。 Further, in the battery storage device 64 of the present embodiment, the cable support bracket 201 extends below the connecting portion of the power cable 142 and the high-voltage terminal pin 140 while partially overlapping the connecting portion in the vertical direction. Therefore, when the terminal holding member 149 is lowered by the operation of the operation lever 44 or the like, the cable support bracket 201 can prevent the connection portion between the power cable 142 and the high voltage terminal pin 140 from interfering with the surrounding members. .
　なお、本発明は上記の実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の設計変更が可能である。例えば、上記の実施形態においては、電力ケーブル１４２を高圧端子ピン１４０に接続して両者の接続状態を維持する固定手段として、ボルト１４６による締結が採用されているが、固定手段はこれに限るものでなく、半田固定等であっても良い。 The present invention is not limited to the above embodiment, and various design changes can be made without departing from the scope of the invention. For example, in the above embodiment, the fastening by the bolt 146 is adopted as a fixing means for connecting the power cable 142 to the high voltage terminal pin 140 and maintaining the connection between the two, but the fixing means is limited thereto Instead, it may be solder fixing or the like.
