The upper portion of the peripheral wall 137a of the luggage case 137 is closed by a seat cushion 8 (refer to FIG. 1, FIG. 27, and FIG. 28) for the rider to ride. The seat cushion 8 can be opened and closed in the vertical direction by using the front end side as a hinge fulcrum. Therefore, the upper part of the luggage compartment 137 and the battery storage device 64 is opened and closed by the seat cushion 8.

如第17圖所示，在樹脂盒部132F(132R)之偏靠前部的底壁，係設有：可允許來自下方的電池盒側連接端子43進行***與脫離的開口部138。在開口部138的下方係可升降地配置著：電池盒側連接端子43以及一體地支承該電池盒側連接端子43的端子支承塊139。As shown in FIG. 17, the bottom wall of the resin case portion 132F (132R) that is closer to the front is provided with an opening 138 that allows the battery case side connection terminal 43 from below to be inserted and removed. Below the opening 138, a battery case-side connection terminal 43 and a terminal support block 139 that integrally supports the battery case-side connection terminal 43 are arranged up and down.

第18圖是從斜上方觀看電池盒側連接端子43及其支承部的圖。 如第17圖和第18圖所示，電池盒側連接端子43係具有：可嵌合連接到電池62A(62B)側的高壓端子47之一對高壓端子插銷140；可嵌合連接到電池62A(62B)側的訊號端子48之複數個訊號端子插銷141。高壓端子插銷140與訊號端子插銷141係沿著車身寬度方向配置成橫向排成一列。高壓端子插銷140係分別配置在複數個訊號端子插銷141的車身寬度方向外側。配置在車身寬度方向兩側的各高壓端子插銷140之上端部的高度是高於訊號端子插銷141之上端部的高度。因此，當電池盒側連接端子43與端子支承塊139一體地從退避位置P2移位到連接位置P1時，高壓端子插銷140係較之訊號端子插銷141更早與電池62A(62B)側的端子部41進行接觸。FIG. 18 is a diagram of the battery case side connection terminal 43 and its supporting portion viewed obliquely from above. As shown in FIGS. 17 and 18, the battery case-side connection terminal 43 has: a pair of high-voltage terminal latches 140 that can be fitted and connected to the battery 62A (62B) side; and can be connected to the battery 62A The plurality of signal terminal pins 141 of the signal terminal 48 on the (62B) side. The high-voltage terminal pins 140 and the signal terminal pins 141 are arranged in a horizontal row along the width direction of the vehicle body. The high-voltage terminal pins 140 are respectively arranged on the outer side of the plurality of signal terminal pins 141 in the width direction of the vehicle body. The height of the upper end of each high-voltage terminal pin 140 disposed on both sides in the width direction of the vehicle body is higher than the height of the upper end of the signal terminal pin 141. Therefore, when the battery case side connection terminal 43 and the terminal support block 139 are integrally displaced from the retreat position P2 to the connection position P1, the high voltage terminal pin 140 is earlier than the signal terminal pin 141 and the terminal on the battery 62A (62B) side The part 41 makes contact.

又，在端子支承塊139的下端係設有：用來將電纜線142(電線)連接到高壓端子插銷140之電纜線連接壁143；用來將訊號線144(電線)連接到訊號端子插銷141之訊號線連接部145。電纜線連接壁143係分別配置在訊號線連接部145之車身寬度方向外側。用來將電纜線142的金屬導線連接到高壓端子插銷140的螺栓146係從車身寬度方向外側締結到電纜線連接壁143上。螺栓146係構成：可將電纜線142電性連接到高壓端子插銷140，並且在物理性上也是牢固地連接固定的固定元件。In addition, the lower end of the terminal support block 139 is provided with: a cable connection wall 143 for connecting the cable 142 (wire) to the high-voltage terminal latch 140; and for connecting the signal wire 144 (wire) to the signal terminal latch 141之信号线连接部145 The signal line connecting portion 145. The cable connection walls 143 are respectively arranged on the outer side of the signal line connection portion 145 in the width direction of the vehicle body. The bolt 146 for connecting the metal wire of the cable 142 to the high-voltage terminal pin 140 is connected to the cable connection wall 143 from the outer side in the width direction of the vehicle body. The bolt 146 is composed of: a cable 142 that can be electrically connected to the high-voltage terminal pin 140, and is also physically connected to a fixed fixing element.

再者，如第17圖所示，在端子支承塊139係安裝著電纜線支承托架201。在電纜線支承托架201上，係保持著被箍夾裝置202束集在一起的電纜線142與訊號線144。電纜線支承托架201係被支承在從端子支承塊139之偏靠在車身寬度方向的其中一側的下端部往下方突設之未圖示的支架。電纜線支承托架201係從端子支承塊139側往下方延伸之後，以沿著電纜線142、訊號線144的拉出方向的方式，在車身寬度方向上彎曲成略呈Ｊ字狀。箍夾裝置202係被支承在電纜線支承托架201的彎曲部的前端側。電纜線支承托架201的下端與箍夾裝置202係位於較之端子支承塊139的電纜線連接壁143、訊號線連接部145更下方的位置。Furthermore, as shown in FIG. 17, the cable support bracket 201 is attached to the terminal support block 139. The cable support bracket 201 holds the cable 142 and the signal line 144 bundled together by the clamp device 202. The cable support bracket 201 is supported by a bracket (not shown) that protrudes downward from the lower end of the terminal support block 139 that is one side of the vehicle body in the width direction. After the cable support bracket 201 extends downward from the terminal support block 139 side, it is bent in a J-shape in the width direction of the vehicle body so as to follow the pull-out direction of the cable 142 and the signal line 144. The clamp device 202 is supported on the front end side of the bent portion of the cable support bracket 201. The lower end of the cable support bracket 201 and the clamp device 202 are located below the cable connection wall 143 and the signal line connection portion 145 of the terminal support block 139.

在端子支承塊139之較電池盒側連接端子43更位於車身寬度方向外側的位置，係朝上方突設有一對作為電池盒側導引部之導引用突起147。導引用突起147的整體係形成略圓柱狀，在其前端部係設置了球面狀的彎曲面、或者、尖細狀的錐面。左右的各導引用突起147是較之電池盒側連接端子43的高壓端子插銷140、訊號端子插銷141的上端部更往上方突出。A pair of guide protrusions 147 serving as guides on the battery case side protrudes upwards at a position of the terminal support block 139 that is located on the outer side in the width direction of the vehicle body than the connection terminal 43 on the battery case side. The entire guide protrusion 147 is formed in a substantially cylindrical shape, and a spherical curved surface or a tapered tapered surface is provided at the front end portion thereof. The left and right guide protrusions 147 protrude upward from the upper ends of the high-voltage terminal latch 140 and the signal terminal latch 141 of the battery box-side connection terminal 43.

另一方面，在被收納在樹脂盒部132F(132R)內的電池62A(62B)的下表面，係設有：可收容端子支承塊139側之左右的導引用突起147之一對導引孔148。導引孔148係構成電池側導引部。因此，當電池62A(62B)被收納在樹脂盒部132F(132R)內的狀態下，將電池盒側連接端子43朝向連接位置P1(請參考第17圖，第25圖，第26圖)上昇的話，在電池盒側連接端子43接觸連接到電池62A(62B)的端子部41之前，導引用突起147將會先***到導引孔148。在本實施方式中，導引用突起147係被設定成：當電池盒側連接端子43處於退避位置P2時，導引用突起147與導引孔148的抵接部的分開距離L1係短於電池盒側連接端子43與電池62A(62B)的端子部41的分開距離L2。如第17圖所示，導引用突起147之電池方向的導引端也就是該導引用突起147的上端147e係形成在：較之電池盒側連接端子43之電池方向的端子端也就是高壓端子插銷140的上端140e更上方側(電池側)。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 147 that can accommodate the left and right guide protrusions 147 on the terminal support block 139 side 148. The guide hole 148 constitutes a battery-side guide portion. Therefore, when the battery 62A (62B) is stored in the resin case portion 132F (132R), the battery case side connection terminal 43 is raised toward the connection position P1 (please refer to FIG. 17, FIG. 25, and FIG. 26) If the connection terminal 43 on the battery case side contacts the terminal portion 41 connected to the battery 62A (62B), the guide protrusion 147 will be inserted into the guide hole 148. In this embodiment, the guide protrusion 147 is set such that when the battery case side connection terminal 43 is at the retreat position P2, the separation distance L1 of the abutment portion of the guide protrusion 147 and the guide hole 148 is shorter than the battery case The side connection terminal 43 is separated from the terminal portion 41 of the battery 62A (62B) by a distance L2. As shown in FIG. 17, the guide end of the guide protrusion 147 in the battery direction, that is, the upper end 147e of the guide protrusion 147, is formed as compared to the battery direction terminal end of the battery box side connection terminal 43, which is the high voltage terminal The upper end 140e of the latch 140 is on the upper side (battery side).

端子移位機構45係具備：藉由端子支承塊139來保持電池盒側連接端子43的端子保持構件149。端子保持構件149係由金屬板材所製成的，具有：沿著車身寬度方向延伸的基座壁149a；從基座壁149a之車身寬度方向的兩端部往上方側彎折並延伸的左右一對連結壁149b。在基座壁149a之車身寬度方向的中央領域，形成有一個長孔狀的插通孔150。在基座壁149a的下表面側，係藉由連結銷151與彈簧單元152來保持著端子支承塊139。被保持在基座壁149a的端子支承塊139之其中一部分與電池盒側連接端子43係通過插通孔150而朝向基座壁149a的上方側突出。The terminal displacement mechanism 45 includes a terminal holding member 149 that holds the connection terminal 43 on the battery case side by the terminal support block 139. The terminal holding member 149 is made of metal sheet material, and has: a base wall 149a extending in the width direction of the vehicle body; left and right sides bent and extending upward from both ends of the base wall 149a in the width direction of the vehicle body To the connecting wall 149b. In the center area of the base wall 149a in the width direction of the vehicle body, a long hole-like insertion hole 150 is formed. On the lower surface side of the base wall 149a, the terminal support block 139 is held by the connecting pin 151 and the spring unit 152. A part of the terminal support block 139 held by the base wall 149a and the battery case side connection terminal 43 pass through the insertion hole 150 to protrude upward of the base wall 149a.

在端子支承塊139之車身寬度方向的兩個緣部，係形成有可供連結銷151穿插的插通孔153。插通孔153的內徑係形成比連結銷151的外徑更大。端子支承塊139係可以在插通孔153與連結銷151的間隙的範圍內，在略水平方向(與端子部41的連接方向交叉的方向)上進行移位。因此，被支承在端子支承塊139上的電池盒側連接端子43，係以可對於：與端子部41的連接方向交叉的方向進行相對移位的方式，被保持在端子保持構件149。At two edges of the terminal support block 139 in the width direction of the vehicle body, insertion holes 153 through which the connection pins 151 can be inserted are formed. The inner diameter of the insertion hole 153 is formed larger than the outer diameter of the coupling pin 151. The terminal support block 139 can be displaced in a slightly horizontal direction (a direction crossing the connection direction of the terminal portion 41) within the range of the gap between the insertion hole 153 and the connection pin 151. Therefore, the battery case side connection terminal 43 supported on the terminal support block 139 is held by the terminal holding member 149 so as to be relatively displaceable in a direction crossing the connection direction of the terminal portion 41.

連結銷151係可滑動地***設在端子保持構件149的基座壁149a上的支承孔198。在連結銷151的上端部係呈一體地設置了防脫落凸緣151a。連結銷151係利用防脫落凸緣151a抵接到基座壁149a的上表面，而可以防止從基座壁149a掉落。The coupling pin 151 is slidably inserted into the support hole 198 provided in the base wall 149 a of the terminal holding member 149. An anti-falling flange 151a is integrally provided at the upper end of the connecting pin 151. The coupling pin 151 abuts against the upper surface of the base wall 149a by the anti-falling flange 151a, and can prevent falling from the base wall 149a.

彈簧單元152係具有：有底圓筒狀之金屬製的彈簧單元外筒154；可抵接在彈簧單元外筒154的開口端之圓板狀的止動板155；裝設在彈簧單元外筒154的內側底面與止動板155之間的彈性構件也就是線圈彈簧156。彈簧單元152係以彈簧單元外筒154的外側底面抵接在基座壁149a的下表面的狀態下，配置在基座壁149a的下方。連結銷151係貫穿過彈簧單元外筒154的底壁，在彈簧單元外筒154的下方結合到止動板155。又，線圈彈簧156係配置在連結銷151的外圍領域。The spring unit 152 includes: a metal spring unit cylinder 154 with a bottomed cylinder; a disc-shaped stop plate 155 that can abut on the open end of the spring unit cylinder 154; The elastic member between the inner bottom surface of 154 and the stop plate 155 is the coil spring 156. The spring unit 152 is arranged below the base wall 149a with the outer bottom surface of the spring unit outer cylinder 154 abutting against the lower surface of the base wall 149a. The connecting pin 151 passes through the bottom wall of the spring unit outer cylinder 154 and is coupled to the stopper plate 155 below the spring unit outer cylinder 154. In addition, the coil spring 156 is arranged in the peripheral area of the connecting pin 151.

電池盒側連接端子43與端子支承塊139係藉由彈簧單元152與連結銷151而被吊掛支承於端子保持構件149。彈簧單元外筒154與止動板155係一直都維持在分開狀態，直到電池盒側連接端子43被從上方施加了既定以上的按壓荷重為止。在這種分開狀態下，如果電池盒側連接端子43被施加既定以上的按壓荷重的話，端子支承塊139將會壓縮線圈彈簧156使其移位，而使其相對於端子保持構件149朝往下方進行移位。端子支承塊139以這種方式，相對於端子保持構件149進行移位既定量以上的話，止動板155將會抵接到彈簧單元外筒154，藉此，來限制端子支承塊139(電池盒側連接端子43)對於端子保持構件149的相對移位(請參考第26圖)。The battery 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 spring unit outer cylinder 154 and the stopper plate 155 are maintained in a separated state until the battery box side connection terminal 43 is applied with a predetermined or more pressing load from above. In such a separated state, if the battery case side connection terminal 43 is applied with a predetermined or greater pressing load, the terminal support block 139 will compress the coil spring 156 to displace it, so that it faces downward relative to the terminal holding member 149 Shift. In this way, if the terminal support block 139 is displaced relative to the terminal holding member 149 by more than a certain amount, the stop plate 155 will abut against the spring unit outer cylinder 154, thereby restricting the terminal support block 139 (battery case Side connection terminal 43) relative displacement with respect to the terminal holding member 149 (please refer to FIG. 26).

端子保持構件149的左右的各連結壁149b，在樹脂盒部132F(132R)的側部外側的下部領域，係可轉動地被保持在金屬製的連桿板片157的下端。連桿板片157係大致沿著上下方向延伸之縱長的板片構件。左右的各連桿板片157的上端部，係可轉動地連結在操作構件也就是操作拉桿44的左右的拉桿片44a的前端。左右的拉桿片44a之延伸方向的中間領域，係可轉動地被樞支在安裝於電池支承框架110上的左右的各支承用支架135。左右的各連桿板片157，當操作拉桿44被朝向某一方向(第14圖和第16圖中的順時鐘方向)進行轉動操作時，將會被朝向上方側拉提上去，如此一來，可將端子保持構件149之左右的各連結壁149b朝向上方側移位。此時，被保持在端子保持構件149的電池盒側連接端子43將會從退避位置P2移位到連接位置P1。 又，第14圖和第16圖中的元件符號197係安裝在左右的支承用支架135的下端附近，用來補強樹脂盒部132F(132R)的外圍領域的補強框架。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 area outside the side of the resin box portion 132F (132R). The link plate 157 is a vertically long plate member extending substantially in the vertical direction. The upper ends of the left and right link plates 157 are rotatably connected to the front ends of the left and right tie rod pieces 44a of the operation member, that is, the operation tie rod 44. The intermediate area in the extending direction of the left and right tie rod pieces 44a is pivotally supported by the left and right support brackets 135 attached to the battery support frame 110. The left and right link plates 157, when the operating lever 44 is turned in a certain direction (clockwise in Figures 14 and 16), it will be pulled upwards, so that The connection walls 149b on the left and right sides of the terminal holding member 149 can be displaced upward. At this time, the battery case side connection terminal 43 held by the terminal holding member 149 will be displaced from the retreat position P2 to the connection position P1. In addition, the element symbol 197 in FIGS. 14 and 16 is installed near the lower ends of the left and right support brackets 135, and is used to reinforce the reinforcing frame in the outer area of the resin box portion 132F (132R).

如第17圖所示，左右的各連桿板片157的下端與端子保持構件149之左右的連結壁149b，是因為轉動銷158***在長孔159內而連繫在一起。轉動銷158係被支承在左右的各連結壁149b，長孔159則是形成在連桿板片157。因此，只要利用操作拉桿44進行操作，就可以將連桿板片157往上方拉提，同時，如第17圖(B)中的(I)、(II)所示，轉動銷158將會在長孔159內進行無作用的滑動，來配合連桿板片157之既定的行程長度。其結果，當操作拉桿44開始進行操作之後，端子保持構件149將會稍後一點才開始往上方移位。 又，第17圖(B)是第17圖(A)的E部的動作狀態圖。As shown in FIG. 17, the lower ends of the left and right link plates 157 and the left and right connecting walls 149 b of the terminal holding member 149 are connected because the rotation pin 158 is inserted into the long hole 159. The rotation pin 158 is supported by the left and right connecting walls 149b, and the long hole 159 is formed in the link plate 157. Therefore, as long as the operating lever 44 is used for operation, the link plate 157 can be lifted upward, and at the same time, as shown in (I) and (II) in FIG. 17(B), the rotation pin 158 will be The long hole 159 slides ineffectively to match the predetermined stroke length of the link plate 157. As a result, after the operation lever 44 starts to operate, the terminal holding member 149 will start to move upward a little later. FIG. 17(B) is an operation state diagram of the part E in FIG. 17(A).

又，用來將電池62A(62B)固定在電池盒42的鎖定機構133係具有可動塊160。可動塊160係可轉動地(可移位地)安裝在電池盒42之左右的支承用支架135的上端部。當操作拉桿44從初期位置轉動到既定位置範圍時，可動塊160受到來自操作拉桿44的操作力，將會朝向電池盒42的上表面方向進行轉動。可動塊160被按壓在電池62A(62B)的上表面，因而限制了電池62A(62B)之朝往脫落方向的移位。In addition, the locking 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 of the support bracket 135 on the left and right of the battery case 42. When the operating lever 44 rotates from the initial position to the predetermined position range, the movable block 160 receives the operating force from the operating lever 44 and will rotate toward the upper surface of the battery case 42. The movable block 160 is pressed against the upper surface of the battery 62A (62B), thereby restricting the displacement of the battery 62A (62B) in the direction of falling.

第19圖是從左側的支承用支架135之右上前方觀看操作拉桿44與可動塊160的圖。 操作拉桿44係以第1轉動軸162為中心，可轉動地被支承在支承用支架135。第1轉動軸162是被樞支在支承用支架135之上下方向的略中央的偏靠前部處之軸，係沿著車輛的車身寬度方向配置。又，在部分的圖中只顯示出第1轉動軸162的軸心o1而已。FIG. 19 is a view of the operation lever 44 and the movable block 160 viewed from the upper right front of the left-side support bracket 135. The operation lever 44 is rotatably supported by the support bracket 135 with the first rotation shaft 162 as a center. The first rotation shaft 162 is a shaft that is pivotally supported at the slightly center of the support bracket 135 in the up-down direction and is located near the front, and is arranged along the width direction of the vehicle body. In addition, in some drawings, only the axis o1 of the first rotation shaft 162 is shown.

鎖定機構133的可動塊160，係以與第1轉動軸162正交的第2轉動軸163為中心，可轉動地被支承在支承用支架135。第2轉動軸163是被樞支在支承用支架135的上端部之軸，係沿著車輛的前後方向配置。The movable block 160 of the lock mechanism 133 is rotatably supported by the support bracket 135 with the second rotation shaft 163 orthogonal to the first rotation shaft 162 as a center. The second rotation shaft 163 is a shaft pivotally supported on the upper end portion of the support bracket 135, and is arranged along the front-rear direction of the vehicle.

在本實施方式中，係將第1轉動軸162配置成：讓第1轉動軸162的軸線o1與收納在樹脂盒部132F(132R)內的電池62A(62B)重疊在一起(請參考第20圖(c)，第22圖(c)，第24圖(c)等)。又，第2轉動軸163係配置成：讓第2轉動軸163的軸線o2位於收納在樹脂盒部132F(132R)內的電池62A(62B)的外側位置(請參考第20圖(c)，第22圖(c)，第24圖(c)等)。In this embodiment, the first rotating shaft 162 is arranged such that the axis o1 of the first rotating shaft 162 overlaps the battery 62A (62B) housed in the resin box portion 132F (132R) (refer to the 20th Figure (c), Figure 22 (c), Figure 24 (c), etc.). In addition, the second rotating shaft 163 is arranged such that the axis o2 of the second rotating shaft 163 is positioned outside the battery 62A (62B) housed in the resin box portion 132F (132R) (refer to FIG. 20(c), (Figure 22 (c), Figure 24 (c), etc.).

操作拉桿44係具有：沿著車身寬度方向延伸的操作片44b；從操作片44b的兩端部朝大致正交方向彎折後再延伸出去的左右的拉桿片44a。左右的拉桿片44a之延伸方向的中間領域，是藉由第1轉動軸162而被支承在左右的支承用支架135。左右的拉桿片44a從側面觀看係彎折成略呈L字狀(前端部朝向前方突出的略呈L字狀)。以下，係將包含拉桿片44a的彎折部在內的操作片44b側稱為：第1延伸部44a-1；將包含彎折部在內之操作片44b的相反側稱為第2延伸片44a-2。左右的拉桿片44a，第2延伸片44a-2之延伸方向的略中間位置係經由第1轉動軸162而被支承在支承用支架135。連桿板片157的上端部，係經由連結銷164而可轉動地連結在第2延伸片44a-2的前端部。The operation lever 44 includes an operation piece 44b extending in the width direction of the vehicle body, and left and right lever pieces 44a that are bent in substantially orthogonal directions from both end portions of the operation piece 44b and then extend out. The intermediate area in the extending direction of the left and right tie rod pieces 44a is supported by the left and right support brackets 135 by the first rotating shaft 162. The left and right tie rod pieces 44a are bent into a slightly L shape when viewed from the side (a slightly L shape with a front end protruding forward). Hereinafter, the side of the operation piece 44b including the bent portion of the tie bar piece 44a is referred to as: a first extension 44a-1; and the opposite side of the operation piece 44b including the bent portion is referred to as a second extension 44a-2. The left and right tie rod pieces 44a and the slightly middle position in the extending direction of the second extending piece 44a-2 are supported by the support bracket 135 via the first rotating shaft 162. The upper end portion of the link plate piece 157 is rotatably connected to the front end portion of the second extension piece 44a-2 via a connecting pin 164.

如第19圖所示，鎖定機構133的可動塊160係具有：樞支部160a；移位限制壁160b(作為電池限制部)；彈性體塊160c(作為電池限制部)；保持力受力壁160d(作為保持力受力部)；凸輪壁160e。樞支部160a係可轉動地被支承在第2轉動軸163。移位限制壁160b係連設在樞支部160a，當移位到樹脂盒部132F(132R)的內側領域時，可用來限制電池62A(62B)朝上揚方向移位。彈性體塊160c係被安裝在移位限制壁160b的其中一面，當移位限制壁160b限制電池62A(62B)朝上揚方向移位時，將會直接抵接在電池62A的上表面。此時，彈性體塊160c將會彈性變形而將彈撥力作用在電池62A的上表面。As shown in FIG. 19, the movable block 160 of the locking mechanism 133 has: a pivot portion 160a; a displacement limiting wall 160b (as a battery limiting portion); an elastic body block 160c (as a battery limiting portion); and a holding force receiving wall 160d (As a holding force receiving portion); cam wall 160e. The pivot portion 160a is rotatably supported by the second rotation shaft 163. The displacement restricting wall 160b is connected to the pivot portion 160a, and can be used to restrict the displacement of the battery 62A (62B) in the upward direction when displaced to the inner area of the resin box portion 132F (132R). The elastic block 160c is installed on one side of the displacement restricting wall 160b. When the displacement restricting wall 160b restricts the displacement of the battery 62A (62B) in the upward direction, it will directly abut on the upper surface of the battery 62A. At this time, the elastic body block 160c will elastically deform to apply a plucking force to the upper surface of the battery 62A.

可動塊160的移位限制壁160b與彈性體塊160c(作為電池限制部)，若從電池62A，62B***到樹脂盒部132F(132R)時的方向觀看，當電池非固定狀態時，兩者是位在電池62A，62B的外側位置(請參考第20圖(c))，當電池固定狀態時，兩者是與電池62A，62B重疊在一起(請參考第22圖(c)，第24圖(c))。When the displacement restricting wall 160b of the movable block 160 and the elastic body block 160c (as the battery restricting portion) are viewed from the direction when the batteries 62A and 62B are inserted into the resin case portion 132F (132R), when the battery is not fixed, both It is located outside the batteries 62A, 62B (please refer to Figure 20 (c)), when the battery is fixed, the two overlap with the batteries 62A, 62B (please refer to Figure 22 (c), 24 Figure (c)).

保持力受力壁160d係連設在樞支部160a，並且在第2轉動軸163的外周圍處，朝往與移位限制壁160b大致形成直角的方向延伸。保持力受力壁160d係承受來自操作拉桿44的拉桿片44a之保持荷重，因而維持以移位限制壁160b與彈性體塊160c來限制電池62A(62B)往上揚方向移位的狀態。凸輪壁160e係在移位限制壁160b與保持力受力壁160d的前部側，將兩者連接在一起的壁，係具有：從移位限制壁160b側朝往保持力受力壁160d的背面160d-1(作為保持力受力面)的方向之圓滑且連續的凸輪面160e-1。The holding force receiving wall 160d is connected to the pivot portion 160a, and extends at a substantially right angle to the displacement restricting wall 160b at the outer periphery of the second rotation shaft 163. The holding force receiving wall 160d receives the holding load from the lever piece 44a of the operating lever 44, and thus maintains the state in which the displacement restricting wall 160b and the elastic body block 160c restrict the displacement of the battery 62A (62B) in the upward direction. The cam wall 160e is a wall connecting the displacement restricting wall 160b and the holding force receiving wall 160d at the front side, and has a wall facing the retaining force receiving wall 160d from the displacement restricting wall 160b side The cam surface 160e-1 is smooth and continuous in the direction of the back surface 160d-1 (serving force receiving surface).

在本實施方式中，保持力受力壁160d(作為保持力受力部)，從沿著第1轉動軸162的方向觀看，當處於電池固定狀態時，係與操作拉桿44的拉桿片44a重疊在一起(請參考第19圖)。In this embodiment, the holding force receiving wall 160d (as a holding force receiving portion) is viewed from the direction along the first rotation axis 162, and when the battery is in a fixed state, it overlaps with the lever piece 44a of the operation lever 44 Together (please refer to Figure 19).

鎖定機構133的可動塊160，係可因應操作拉桿44的轉動操作而能夠在於：移位限制壁160b與彈性體塊160c往上方跳起來的鎖定解除位置；以及移位限制壁160b與彈性體塊160c朝往樹脂盒部132F(132R)的內側方向近乎傾倒90°的鎖定位置之間進行轉動。鎖定機構133，當移位限制壁160b與彈性體塊160c處於鎖定解除位置時，係成為：電池非固定狀態；當移位限制壁160b與彈性體塊160c處於鎖定位置時，係成為：電池固定狀態。再者，各可動塊160係可利用未圖示的彈簧，全時性地被朝往上方跳起來的方向彈推。The movable block 160 of the lock mechanism 133 can be located in an unlocked position where the displacement restricting wall 160b and the elastic body block 160c jump upward in response to the rotation operation of the operating lever 44; and the displacement restricting wall 160b and the elastic body block 160c rotates between the locked positions that are tilted by approximately 90° toward the inside of the resin box portion 132F (132R). The locking mechanism 133 becomes the battery non-fixed state when the displacement restricting wall 160b and the elastic body block 160c are in the unlocked position; when the displacement restricting wall 160b and the elastic body block 160c are in the locked position, it becomes: the battery is fixed status. In addition, each movable block 160 can be urged in the direction of jumping upward at all times by using a spring (not shown).

處於電池非固定狀態時，操作拉桿44係往前方傾倒最大角度，此時的操作拉桿44的操作片44b是移位到較之樹脂盒部132F(132R)的插脫口136(內壁)更為前方側。將此時的操作拉桿44的位置稱為：初期位置。又，處於電池固定狀態時，操作拉桿44係被往後部上方側拉起來，此時的操作拉桿44的操作片44b是移位到樹脂盒部132F(132R)的插脫口136的上方位置。When the battery is in a non-fixed state, the operating lever 44 is tilted forward to the maximum angle. At this time, the operating piece 44b of the operating lever 44 is displaced more than the insertion/removal port 136 (inner wall) of the resin box portion 132F (132R) For the front side. The position of the operating lever 44 at this time is called an initial position. In addition, when the battery is in a fixed state, the operating lever 44 is pulled upward toward the rear, and the operating piece 44b of the operating lever 44 at this time is displaced to the position above the insertion/detachment opening 136 of the resin box portion 132F (132R).

又，在操作拉桿44的拉桿片44a之中的第1延伸部44a-1，係形成有一個朝後方側膨凸的凸輪突起165。當操作拉桿44從初期位置被朝向上部後方側拉起來時，凸輪突起165就已經抵接在處於跳上來的狀態的可動塊160的凸輪面160e-1，一邊在該凸輪面160e-1上進行滑動，一邊將可動塊160朝往轉動方向進行按壓。如此一來，可動塊160就從鎖定解除位置被轉動操作到鎖定位置。以這種方式來進行操作拉桿44的拉起操作，當凸輪突起165的接觸部抵達凸輪面160e-1的終端位置時，拉桿片44a的內側面(面向車身寬度方向內側的這一面)就會抵接在可動塊160的保持力受力壁160d的背面160d-1。這種狀態將可持續到操作拉桿44抵達最大的拉起操作位置為止。In addition, in the first extension portion 44a-1 of the lever piece 44a of the operation lever 44, a cam protrusion 165 bulging toward the rear side is formed. When the operating lever 44 is pulled up toward the upper rear side from the initial position, the cam protrusion 165 has already abutted on the cam surface 160e-1 of the movable block 160 in the jumped up state, while performing on the cam surface 160e-1 While sliding, the movable block 160 is pressed in the direction of rotation. As a result, the movable block 160 is rotated from the unlocked position to the locked position. In this way, when the operating lever 44 is pulled up, when the contact portion of the cam protrusion 165 reaches the end position of the cam surface 160e-1, the inner side surface of the lever piece 44a (the side facing the inner side in the vehicle body width direction) The rear surface 160d-1 of the holding force receiving wall 160d that abuts against the movable block 160 is. This state will continue until the operating lever 44 reaches the maximum pulling operation position.

因為鎖定機構133與端子移位機構45是被共通的操作拉桿44所操作，因此，鎖定機構133與端子移位機構45的各作動狀態是取決於操作拉桿44的轉動操作位置。端子移位機構45與鎖定機構133是互相連動，鎖定機構133是因為受到操作拉桿44的操作而將電池62A(62B)加以固定，在這種狀態下，端子移位機構45則是將電池盒側連接端子43移位到連接位置P1。Since the locking mechanism 133 and the terminal shift mechanism 45 are operated by the common operating lever 44, the respective operating states of the locking mechanism 133 and the terminal shift mechanism 45 depend on the rotational operating position of the operating lever 44. The terminal shift mechanism 45 and the lock mechanism 133 are interlocked with each other. The lock mechanism 133 is fixed by the operation lever 44 to fix the battery 62A (62B). In this state, the terminal shift mechanism 45 is to hold the battery box The side connection terminal 43 is displaced to the connection position P1.

茲佐以第20圖～第26圖來說明：將電池62A(62B)***樹脂盒部132F(132R)之後，將電池62A(62B)固定在樹脂盒部132F(132R)內，並且將電池盒側連接端子43連接到電池62A(62B)的端子部41之一連串的動作。 第20圖所示的狀態，操作拉桿44是處於往前方最大傾倒的初期位置。此時，操作拉桿44的拉桿片44a的前端部位於最下方位置，連桿板片157與端子移位機構45的端子保持構件149也移位到最下方位置。在這種狀態下，電池62A(62B)是被***到樹脂盒部132F(132R)內。此時，第17圖所示，電池盒側連接端子43是位於退避位置P2。又，鎖定機構133的可動塊160是位於跳起來在上方的鎖定解除位置。The following diagrams are illustrated in FIGS. 20 to 26: After inserting the battery 62A (62B) into the resin case 132F (132R), the battery 62A (62B) is fixed in the resin case 132F (132R), and the battery case The side connection terminal 43 is connected to one of the terminal portions 41 of the battery 62A (62B) for a series of operations. In the state shown in FIG. 20, the operation lever 44 is in the initial position where it is tipped forward the most. At this time, the front end portion of the lever piece 44a of the operation lever 44 is located at the lowermost position, and the link plate piece 157 and the terminal holding member 149 of the terminal displacement mechanism 45 are also displaced to the lowermost position. In this state, the battery 62A (62B) is inserted into the resin case portion 132F (132R). At this time, as shown in FIG. 17, the battery case side connection terminal 43 is located at the retracted position P2. In addition, the movable block 160 of the lock mechanism 133 is located at the unlocked position where it jumps up.

從這種狀態對於操作拉桿44進行拉起操作的話，將會如第21圖所示般地，操作拉桿44的凸輪突起165係抵接在可動塊160的凸輪面160e-1，一邊沿著該凸輪面160e-1進行滑動，一邊將可動塊160朝往鎖定位置方向進行轉動。 在開始進行這種操作拉桿44的操作初期，連桿板片157雖然是被拉桿片44a所往上拉起，但是在連桿板片157與端子保持構件149之間，係有前述的利用長孔159來進行的無作用的滑動期間，因此，此時之端子保持構件149的上昇移位的開始將會受到延遲。When the operation lever 44 is pulled up from this state, the cam protrusion 165 of the operation lever 44 abuts on the cam surface 160e-1 of the movable block 160 as shown in FIG. The cam surface 160e-1 slides and rotates the movable block 160 toward the locked position. At the beginning of the operation to start the operation of the lever 44, although the link plate 157 is pulled upward by the lever 44 a, there is the aforementioned utilization length between the link plate 157 and the terminal holding member 149. During the inactive sliding period performed by the hole 159, the start of the upward displacement of the terminal holding member 149 at this time will be delayed.

一旦進行了操作拉桿44的拉起操作的話，就會如第22圖所示般地，可動塊160開始進行轉動，可動塊160的彈性體塊160c就會抵接在電池62A的上表面。此時，端子移位機構45的端子保持構件149是藉由：操作拉桿44之經由連桿板片157所進行的拉起操作，而朝上方移位。又，此時係如第23圖所示般地，端子支承塊139的導引用突起147係嵌入電池62A(62B)的下表面側的導引孔148，因而，與端子支承塊139和電池盒側連接端子43的端子連接方向交叉的方向的位置受到微調整。When the operation lever 44 is pulled up, the movable block 160 starts to rotate as shown in FIG. 22, and the elastic block 160c of the movable block 160 abuts on 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 the pulling operation of the operating lever 44 via the link plate 157. At this time, as shown in FIG. 23, the guide protrusion 147 of the terminal support block 139 is fitted into the guide hole 148 on the lower surface side of the battery 62A (62B). Therefore, it is connected to the terminal support block 139 and the battery case The position of the side connection terminal 43 in the direction crossing the terminal connection direction is finely adjusted.

更進一步地對於操作拉桿44進行拉起操作的話，將會如第24圖所示般地，操作拉桿44的拉桿片44a將會繞到可動塊160的保持力受力壁160d的背面側進行抵接。如此一來，可動塊160的移位限制壁160b將會轉動到既定的移位限制位置，經由彈性體塊160c來限制電池62A(62B)往上揚方向移位。此時，係如第25圖所示般地，端子移位機構45的端子保持構件149，是受到操作拉桿44經由連桿板片157所進行的拉起操作而更進一步地往上昇，電池盒側連接端子43就移位到連接位置P1。如此一來，電池盒側連接端子43就會嵌合連接到電池62A(62B)的端子部41。Further, when the operation lever 44 is pulled up, as shown in FIG. 24, the lever piece 44a of the operation lever 44 will wrap around the back side of the holding force receiving wall 160d of the movable block 160 Pick up. As a result, the displacement restricting wall 160b of the movable block 160 will rotate to a predetermined displacement restricting position, and the displacement of the battery 62A (62B) in the upward 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 lifted up by the operation of the operating lever 44 via the link plate 157, and the battery case The side connection terminal 43 is displaced to the connection position P1. In this way, the battery box side connection terminal 43 is fitted and connected to the terminal portion 41 of the battery 62A (62B).

從第24圖所示的狀態，更進一步地將操作拉桿44往拉起方向操作一既定量的話，端子移位機構45就會如第26圖所示般地，使得端子保持構件149更往上方移位。此時，彈簧單元152的線圈彈簧156被壓縮，電池盒側連接端子43以既定的荷重被按壓在電池62A(62B)的端子部41。如此一來，利用鎖定機構133對於電池62A(62B)的鎖定以及利用端子移位機構45所進行的端子連接就完畢了。 再者，在本實施方式中，係在電池收納裝置64內的某處設有一聲響機構，係當操作拉桿44被進行操作到達操作完畢位置時，就會發出撞擊聲之類的喀搭聲來讓操作者知道已經是操作完畢了。From the state shown in FIG. 24, if the operating lever 44 is further operated in the pulling direction for a given amount, the terminal shifting mechanism 45 will move the terminal holding member 149 further upward as shown in FIG. 26. Shift. At this time, the coil spring 156 of the spring unit 152 is compressed, and the battery case side connection terminal 43 is pressed against the terminal portion 41 of the battery 62A (62B) with a predetermined load. In this way, the locking of the battery 62A (62B) by the locking mechanism 133 and the terminal connection by the terminal displacement mechanism 45 are completed. Furthermore, in this embodiment, a sound mechanism is provided somewhere in the battery storage device 64, and when the operation lever 44 is operated to reach the operation-completed position, a clicking sound such as a knocking sound is generated. Let the operator know that the operation is completed.

第27圖係操作拉桿44處於操作完畢前的狀態時之電池收納裝置64與坐墊8之部分剖面側面圖。第28圖係操作拉桿44處於鎖定位置的狀態(操作完畢狀態)時之電池收納裝置64與坐墊8之部分剖面側面圖。 如第27圖和第28圖所示，坐墊8係在其前端部側具有一沿著車身寬度方向的鉸鏈軸170，並且係以該鉸鏈軸170為中心，可轉動地被支承在車體上。又，在坐墊8的內側面，設有一對前後分開的突起171A，171B。突起171A，171B係從坐墊8的內側面朝向下方突出。這一對突起171A，171B係被設定成：當電池收納裝置64之前後的操作拉桿44處於完全地操作到達操作結束位置的狀態時，係如第28圖所示般地，並不會接觸到操作拉桿44，而是進入到各操作拉桿44的前方側的空間內。 又，這一對突起171A，171B係被設定成：當電池收納裝置64之前後的操作拉桿44處於操作完畢前的狀態時，係第27圖所示般地，將會抵接到操作拉桿44的操作片44b的上表面。因此，只要有其中一個操作拉桿44尚未完全到達操作完畢位置時，坐墊8就會受到突起117A、117B的阻礙而無法進行關閉。如此一來，可以讓作業者得知：操作拉桿44尚未到達操作完畢位置。FIG. 27 is a partial cross-sectional side view of the battery storage device 64 and the seat cushion 8 when the operation lever 44 is in a state before the operation is completed. FIG. 28 is a partial cross-sectional side view of the battery storage device 64 and the seat cushion 8 when the operation lever 44 is in the locked position (operation completed state). As shown in FIGS. 27 and 28, the seat cushion 8 has a hinge shaft 170 along the width direction of the vehicle body at the front end side, and the hinge shaft 170 is rotatably supported on the vehicle body with the hinge shaft 170 as the center. . In addition, on the inner surface of the seat cushion 8, a pair of protrusions 171A, 171B spaced back and forth are provided. The protrusions 171A and 171B protrude downward from the inner surface of the seat cushion 8. The pair of protrusions 171A, 171B are set so that when the operation lever 44 before and after the battery storage device 64 is fully operated to reach the operation end position, it will not touch as shown in FIG. 28 The operating lever 44 is moved into the space on the front side of each operating lever 44. In addition, the pair of protrusions 171A, 171B are set so that when the operation lever 44 before and after the battery storage device 64 is in the state before the operation is completed, it will come into contact with the operation lever 44 as shown in FIG. 27 The upper surface of the operation piece 44b. Therefore, as long as one of the operation levers 44 has not completely reached the operation-completed position, the seat cushion 8 is hindered by the protrusions 117A and 117B and cannot be closed. In this way, the operator can be informed that the operation lever 44 has not reached the operation completion position.

再者，依據操作拉桿44的位置的不同，亦可因為進行關閉坐墊8的操作時，突起171A，171B抵接在操作拉桿44的操作片44b的上表面，而將操作拉桿44推入到達操作完畢位置為止。 又，在本實施方式中，係設定成：當前後的操作拉桿44處於初期位置時，坐墊8側的突起117A，117B係進入操作拉桿44的後方側的空間而並不接觸到操作拉桿44。In addition, depending on the position of the operating lever 44, the protrusions 171A, 171B abut on the upper surface of the operating piece 44 b of the operating lever 44 when the operation of closing the seat cushion 8 is performed, and the operating lever 44 can be pushed into the operation End position. In this embodiment, when the front and rear operation levers 44 are in the initial position, the protrusions 117A and 117B on the seat cushion 8 side enter the space on the rear side of the operation lever 44 without contacting the operation lever 44.

如第29圖所示，在各樹脂盒部132F，132R的下端，設有朝後下方傾斜的底壁132Fb，132Rb。在各底壁132Fb，132Rb之前後方向略中央的下方，配置有很靠近各底壁132Fb，132Rb之電池支承框架110的橫置管116，122。在各橫置管116，122係固定著往後方延伸之電池盒支承托架116b，122b。在各電池盒支承托架116b，122b，係締結固定著：各底壁132Fb，132Rb之容後說明的締結部134b(請參考第30圖)。As shown in FIG. 29, at the lower end of each of the resin box portions 132F and 132R, bottom walls 132Fb and 132Rb which are inclined downward and rearward are provided. Below each of the bottom walls 132Fb and 132Rb, slightly below the center in the front-rear direction, horizontal tubes 116 and 122 are arranged very close to the battery support frame 110 of the bottom walls 132Fb and 132Rb. The battery case support brackets 116b, 122b extending rearward are fixed to the horizontal tubes 116, 122, respectively. In each battery case support bracket 116b, 122b, the bottom wall 132Fb, 132Rb is attached and fixed to the attachment portion 134b described later (refer to FIG. 30).

在各底壁132Fb，132Rb的前側(較之橫置管116，122更前方)係配置著電池盒側連接端子43。當電池盒側連接端子43位於前述連接位置P1時(圖中的實線所示的位置)，係較之底壁132Fb，132Rb的上表面更往上方突出，而連接到電池62A，62B的端子部41。當電池盒側連接端子43位於前述退避位置P2(圖中的鏈線所示的位置)時，係較之底壁132Fb，132Rb的上表面更往下方降低，而從電池62A，62B的端子部41脫離。On the front side of each of the bottom walls 132Fb and 132Rb (more forward than the horizontal tubes 116 and 122), the battery box side connection terminal 43 is arranged. When the battery box-side connection terminal 43 is located at the aforementioned connection position P1 (the position indicated by the solid line in the figure), it protrudes more upward than the upper surfaces of the bottom walls 132Fb, 132Rb, and is connected to the terminals of the batteries 62A, 62B部41. When the battery box side connection terminal 43 is located at the aforementioned retreat position P2 (the position indicated by the chain line in the figure), it is lowered from the upper surface of the bottom walls 132Fb, 132Rb, and from the terminals of the batteries 62A, 62B 41 break away.

在各底壁132Fb，132Rb的後側(較之橫置管116，122更後方)係設有：可將侵入到樹脂盒部132F，132R內的水予以排出到盒外的排水部180。 以下將同時佐以第30圖～第32圖來進行說明。第30圖～第32圖係顯示出與前側的樹脂盒部132F對應的構造，在以下的說明當中，如果沒有特別地記載的話，都是在說明與前側的樹脂盒部132F對應的構造。與後側的樹脂盒部132R對應的構造，係與前側的樹脂盒部132F相同，因此省略其說明。在第30圖中的線CL係表示：電池62B以及樹脂盒部132F的左右中心(車體左右中心)。On the rear side of each of the bottom walls 132Fb and 132Rb (rear than the horizontal tubes 116 and 122), a water draining portion 180 that discharges water that has entered the resin box portions 132F and 132R to the outside of the box is provided. The following will also be described with reference to FIGS. 30 to 32. FIGS. 30 to 32 show the structure corresponding to the front resin box portion 132F. In the following description, unless otherwise specified, the structure corresponding to the front resin box portion 132F is explained. The structure corresponding to the resin box portion 132R on the rear side is the same as that of the resin box portion 132F on the front side, and therefore its description is omitted. The line CL in FIG. 30 indicates the left and right centers of the battery 62B and the resin case portion 132F (left and right center of the vehicle body).

如第30圖、第32圖所示，在電池62B的下端的四個角落，係安裝著：將偏平球狀的膨出面從電池62B的下端往外突出之減震橡膠RB。在底壁132Fb的四個角落，則是設有：形成了可與各減震橡膠RB的膨出面大致整合的凹面之凹部134a。在底壁132Fb的後側，則是設有：可與左右的凹部134a的前側且是車身寬度方向內側相連接的締結部134b。As shown in FIG. 30 and FIG. 32, the four corners of the lower end of the battery 62B are provided with shock-absorbing rubber RB that protrudes outward from the lower end of the battery 62B with a flat spherical bulging surface. At the four corners of the bottom wall 132Fb, there are provided concave portions 134a that form concave surfaces that can be substantially integrated with the bulging surfaces of the damping rubbers RB. On the rear side of the bottom wall 132Fb, there is provided a connecting portion 134b that can be connected to the front side of the left and right recesses 134a and is inward in the vehicle body width direction.

如第32圖所示，締結部134b係形成往下方突出之有底筒狀，這個締結部134b的下表面係抵接在電池盒支承托架116b的上表面。締結部134b是從上方讓螺栓B1(請參考第30圖)插穿過去，這個螺栓B1則是螺合在電池盒支承托架116b。如此一來，樹脂盒部132F的底壁132Fb就被締結固定到電池盒支承托架116b。As shown in FIG. 32, the connecting portion 134b is formed into a bottomed cylindrical shape protruding downward, and the lower surface of this connecting portion 134b abuts on the upper surface of the battery case support bracket 116b. The connecting portion 134b allows the bolt B1 (refer to FIG. 30) to be inserted from above. The bolt B1 is screwed to the battery case support bracket 116b. In this way, the bottom wall 132Fb of the resin case portion 132F is fixed to the battery case support bracket 116b.

如第30圖所示，在底壁132Fb的前側，係設有一個位於左右的凹部134a的後側且稍微鄰接在車身寬度方向外側的卡止部134c。卡止部134c例如：係供後述的保護構件189的上端前側卡止固定在這個卡止部134c。As shown in FIG. 30, on the front side of the bottom wall 132Fb, a locking portion 134c located on the rear side of the left and right recesses 134a and slightly adjacent to the outer side in the width direction of the vehicle body is provided. The locking portion 134c is, for example, a front end of the upper end of a protection member 189 to be described later which is locked and fixed to this locking portion 134c.

如第31圖和第32圖所示，排水部180係具備：形成在底壁132Fb之例如：左角部的彎曲凹面的排水孔181、以及形成在左右締結部134b的下部之例如：將左後部切開缺口而形成的第二排水孔182。在排水孔181的下方，則是連設著：一個從底壁132Fb往下方突出的噴嘴181a。As shown in FIGS. 31 and 32, the drainage portion 180 includes: a drainage hole 181 formed in the bottom wall 132Fb, for example, a curved concave surface in the left corner, and a lower portion formed in the lower part of the left and right connection portion 134b: The second drain hole 182 is formed by cutting a notch at the rear. Below the drain hole 181, a nozzle 181a protruding downward from the bottom wall 132Fb is connected.

侵入到樹脂盒部132F內的水滴等，係沿著底壁132Fb的傾斜而被引導到排水部180，而從各排水孔181，182的其中任何一個排出到盒外。因為將排水孔181設在底壁132Fb的左側，並且將第二排水孔182也設在凹狀的締結部134b的左側，因此，即使在利用側腳架而讓兩輪機車1的車體往左側傾斜的停車狀態下，也是可以讓侵入到盒內的水從各排水孔181，182順利地排出。Water droplets and the like that have entered the resin box portion 132F are guided to the drain portion 180 along the inclination of the bottom wall 132Fb, and are discharged out of the box from any of the drain holes 181 and 182. Since the drain hole 181 is provided on the left side of the bottom wall 132Fb, and the second drain hole 182 is also provided on the left side of the concave connecting portion 134b, even if the side frame is used to allow the body of the two-wheeled locomotive 1 to In the parking state where the left side is inclined, the water that has entered the box can be smoothly discharged from the drain holes 181 and 182.

如第29圖所示，利用位在前述退避位置P2的電池盒側連接端子43與底壁132Fb，在樹脂盒部132F的下方形成了：從側面觀看，是朝前上方凹陷進去的凹部185。在凹部185內，配置著：電池支承框架110之往車身寬度方向延伸的橫置管116。因為有這個橫置管116的存在，來自車輛側方之外部破壞因素很難對於位在退避位置P2的電池盒側連接端子43的周圍造成不良影響。此外，可很有效率且很緊緻地配置用來保護電池盒側連接端子43的橫置管116。As shown in FIG. 29, the battery case side connection terminal 43 and the bottom wall 132Fb at the retreat position P2 are formed below the resin case portion 132F: viewed from the side, a concave portion 185 that is recessed forward and upward is formed. Inside the recess 185, a horizontal tube 116 extending from the battery support frame 110 in the width direction of the vehicle body is arranged. Because of the presence of this horizontal tube 116, it is difficult for external damage factors from the side of the vehicle to adversely affect the periphery of the battery box-side connection terminal 43 at the retreat position P2. In addition, the horizontal tube 116 for protecting the connection terminal 43 on the battery case side can be efficiently and compactly arranged.

從車輛前後方向觀看，位在前述退避位置P2的電池盒側連接端子43與橫置管116係配置成：互相重疊在一起。位在退避位置P2的電池盒側連接端子43，係因為下降到底壁132Fb的下方，而從樹脂盒部132F的下方大幅度地突出。來自車輛前方的外部破壞因素對於這個電池盒側連接端子43所造成的不良影響，經會受到橫置管116的抑制。再者，在較之電池盒側連接端子43的更前方設有橫置構件的話，來自車輛後方的外部破壞因素對於電池盒側連接端子43所造成的影響也會受到抑制。Viewed from the front-rear direction of the vehicle, the battery box-side connection terminal 43 and the horizontal tube 116 at the retreat position P2 are arranged so as to overlap each other. The connection terminal 43 on the battery case side located at the retreat position P2 is greatly protruded from below the resin case portion 132F by descending below the bottom wall 132Fb. The adverse influence caused by the external destruction factor from the front of the vehicle on this battery box side connection terminal 43 is suppressed by the horizontal tube 116. Furthermore, if a horizontal member is provided in front of the battery box-side connection terminal 43, the influence of external destruction factors from the rear of the vehicle on the battery box-side connection terminal 43 is also suppressed.

在橫置管116係固定著用來支承連接到電動馬達30的電纜線60之電纜線支承托架131。電纜線60雖然是比較粗而具有剛性，但是這個電纜線60係經由電纜線支承托架131而很牢固地被橫置管116所支承。電纜線支承托架131是位於樹脂盒部132F的後端部的下方位置，在其下方保持著電纜線60。電纜線支承托架131係對於電纜線60之從左到右橫跨在電池收納裝置64的下方之部分(左右橫跨部分)加以保持。電纜線60的左右橫跨部分與電纜線支承托架131係被配置在：安裝在前後的樹脂盒部132F，132R的底壁132Fb，132Rb之後述的保護構件189之間。A cable support bracket 131 for supporting the cable 60 connected to the electric motor 30 is fixed to the horizontal pipe 116. Although the cable 60 is relatively thick and rigid, the cable 60 is firmly supported by the horizontal tube 116 via the cable support bracket 131. The cable support bracket 131 is located below the rear end portion of the resin box portion 132F, and holds the cable 60 below it. The cable support bracket 131 holds a portion of the cable 60 that spans under the battery storage device 64 from left to right (left and right crossing portions). The left and right crossing portions of the cable 60 and the cable support bracket 131 are disposed between the bottom walls 132Fb of the front and rear resin box portions 132F, 132R, and the protective member 189 described later.

電池收納裝置64係具備：作為可將電池盒側連接端子43朝上方進行操作的連桿機構之操作拉桿44(請參考第14圖等)。藉由將操作拉桿44從前方朝後方進行擺動操作，電池盒側連接端子43將會從退避位置P2朝向連接位置P1移動，而***到電池62B的端子部41。用來支承操作拉桿44之第1轉動軸162，係在電池盒42之車身寬度方向外側被支承在電池支承框架110。如此一來，可提高操作拉桿44的支承剛性而可獲得良好的操作感。The battery storage device 64 includes an operation lever 44 as a link mechanism that can operate the battery case side connection terminal 43 upward (refer to FIG. 14 etc.). By swinging the operation lever 44 from the front to the rear, the battery box-side connection terminal 43 will move from the retracted position P2 toward the connection position P1 and be inserted into the terminal portion 41 of the battery 62B. The first rotating shaft 162 for supporting the operation lever 44 is supported by the battery support frame 110 on the outer side of the battery case 42 in the width direction of the vehicle body.
