　シート２６の下方で、かつリヤクッション７０およびＰＣＵ５０の上方の位置には、車体上方に開口を有する収納ボックス８０が配設されている。収納ボックス８０は、車体前方側の天地寸法より車体後方側の天地寸法の方が小さく形成されている。収納ボックス８０による収納空間８１は、収納ボックス８０の外周壁とシート底板２６ｂとによって囲まれた空間となる。本実施形態では、シート底板２６ｂに車体上方側に大きく突出する凸形状を形成することで、収納空間８１の天地高さを増やしつつシート２６を開いた際の荷物へのアクセスを容易している。また、車体前方側の底部には、車幅方向中央のリヤクッション７０との干渉を避けるための逃げ凹部が形成されており、一方の車体後方側には、ＰＣＵ５０との干渉を避けるための傾斜部が形成されている。 A storage box 80 having an opening above the vehicle body is disposed below the seat 26 and above the rear cushion 70 and the PCU 50. The storage box 80 is formed such that the vertical dimension on the rear side of the vehicle body is smaller than the vertical dimension on the front side of the vehicle body. A storage space 81 by the storage box 80 is a space surrounded by the outer peripheral wall of the storage box 80 and the seat bottom plate 26b. In the present embodiment, the seat bottom plate 26b is formed with a convex shape that largely protrudes upward in the vehicle body, thereby facilitating access to the luggage when the seat 26 is opened while increasing the height of the storage space 81. . Further, a relief recess for avoiding interference with the rear cushion 70 at the center in the vehicle width direction is formed at the bottom on the front side of the vehicle body, and an inclination for avoiding interference with the PCU 50 on one vehicle body rear side. The part is formed.
　本実施形態では、バッテリＢ、リヤクッション７０およびＰＣＵ５０の配置の工夫により電動二輪車１の低重心化が図られている。具体的には、車体側面視で、バッテリＢおよびリヤクッション７０を後輪ＷＲの上端位置Ａより下方に配設すると共に、ＰＣＵ５０を後輪ＷＲの上端位置Ａに重なる位置に配設している。これにより、バッテリＢ、リヤクッション７０、ＰＣＵ５０という重量物が車体下方寄りに配設されることとなり、車体の重心位置を下げることで電動二輪車１の走行性能が高められる。 In this embodiment, the center of gravity of the electric motorcycle 1 is lowered by devising the arrangement of the battery B, the rear cushion 70, and the PCU 50. Specifically, the battery B and the rear cushion 70 are disposed below the upper end position A of the rear wheel WR and the PCU 50 is disposed at a position overlapping the upper end position A of the rear wheel WR as viewed from the side of the vehicle body. . Thus, heavy objects such as the battery B, the rear cushion 70, and the PCU 50 are disposed closer to the lower side of the vehicle body, and the traveling performance of the electric motorcycle 1 is improved by lowering the position of the center of gravity of the vehicle body.
　また、リヤクッション７０およびＰＣＵ５０が車体下方寄りの位置に配設されるため、これらの上方に配設される収納ボックス８０の容量を拡大することが可能となる。また、バッテリＢをシート２６の前端部２６ｃより前方に配置することで、前輪荷重を増やして走行性能を高めている。さらに、本実施形態では、ＰＣＵ５０を車体側に設けることで、スイングアーム側にＰＣＵを設ける構成に比してバネ下荷重を低減して後輪ＷＲの路面追従性を高めているが、モータ出力が比較的小さくＰＣＵも小型な場合は、ＰＣＵをスイングアーム側に設けて収納ボックス８０の容量をより一層拡大することともできる。 Further, since the rear cushion 70 and the PCU 50 are disposed at positions closer to the lower side of the vehicle body, the capacity of the storage box 80 disposed above these can be increased. Further, the battery B is disposed in front of the front end portion 26c of the seat 26, thereby increasing the front wheel load and improving the traveling performance. Furthermore, in this embodiment, by providing the PCU 50 on the vehicle body side, the unsprung load is reduced and the road surface followability of the rear wheel WR is improved as compared with the configuration in which the PCU is provided on the swing arm side. If the PCU is relatively small and the PCU is also small, the capacity of the storage box 80 can be further increased by providing the PCU on the swing arm side.
　また、本実施形態では、バッテリＢ、リヤクッション７０およびＰＣＵ５０の配置の工夫により電動二輪車１のマスの集中が図られている。具体的には、収納ボックス８０の後部にテールライト６０を近接配置することで、テールライト６０が後輪ＷＲの車軸２３より車体前方に位置するように構成している。換言すれば、テールライト６０は、車軸２３から鉛直方向に伸ばした直線Ｃより車体前方に位置する。これにより、バッテリＢ、リヤクッション７０、ＰＣＵ５０という重量物を車体中央寄りに配置するだけでなく、テールライト６０も車体前方寄りに配置してマスの集中を図っている。これにより、車両の走行性能が高められると共に、斬新なデザインを得ることが可能となる。 Further, in this embodiment, the concentration of the mass of the electric motorcycle 1 is achieved by the arrangement of the battery B, the rear cushion 70, and the PCU 50. Specifically, the tail light 60 is disposed close to the rear portion of the storage box 80 so that the tail light 60 is positioned in front of the vehicle body from the axle 23 of the rear wheel WR. In other words, the taillight 60 is positioned in front of the vehicle body with respect to the straight line C extending in the vertical direction from the axle 23. Thereby, not only the heavy objects such as the battery B, the rear cushion 70, and the PCU 50 are disposed near the center of the vehicle body, but the taillight 60 is also disposed near the front of the vehicle body to concentrate the mass. As a result, the running performance of the vehicle can be improved and a novel design can be obtained.
　さらに、本実施形態では、バッテリＢ、リヤクッション７０およびＰＣＵ５０が、いずれもテールライト６０の車体前方に配設されている。より詳しくは、リヤクッション７０の車体前方側の軸支部７０ａが、バッテリＢの車体後方側に近接配置されるため、傾斜したリヤクッション７０をバッテリＢとＰＣＵ５０との間に効率よく配置して、より一層マスの集中を図ることができる。また、ＰＣＵ５０が、後輪（ＷＲ）の前端位置（Ｄ）と車体前後方向で重なる位置に配設されていることで、ＰＣＵ５０が車体前方寄りの位置に配設されてより一層マスの集中が図られる。 Furthermore, in the present embodiment, the battery B, the rear cushion 70 and the PCU 50 are all disposed in front of the taillight 60 in the vehicle body. More specifically, since the shaft support portion 70a on the vehicle body front side of the rear cushion 70 is disposed close to the vehicle body rear side of the battery B, the inclined rear cushion 70 is efficiently disposed between the battery B and the PCU 50, The mass can be further concentrated. Further, since the PCU 50 is disposed at a position overlapping the front end position (D) of the rear wheel (WR) in the longitudinal direction of the vehicle body, the PCU 50 is disposed at a position closer to the front of the vehicle body, and the mass concentration is further increased. Figured.
　加えて、収納ボックス８０とリヤクッション７０とが近接配置されることで、収納ボックス８０の容量を拡大できると共に、収納ボックス８０に収められた荷物がリヤクッション７０の近傍に位置することとなり、マスの集中を図る効果が維持されやすくなる。また、収納ボックス８０とＰＣＵ５０とが近接配置されることで、収納ボックス８０に収められた荷物がＰＣＵ５０の近傍に位置することとなり、マスの集中を図る効果が維持されやすくなる。 In addition, since the storage box 80 and the rear cushion 70 are arranged close to each other, the capacity of the storage box 80 can be increased, and the luggage stored in the storage box 80 is positioned in the vicinity of the rear cushion 70. The effect of concentrating is easily maintained. Further, since the storage box 80 and the PCU 50 are arranged close to each other, the luggage stored in the storage box 80 is positioned in the vicinity of the PCU 50, and the effect of concentrating the masses is easily maintained.

Thus, the battery B can be lifted, and the battery B can be easily attached and detached.
　充放電コネクタ７５に接続される第３ハーネスＨ３は、車幅方向左側を通ってＰＣＵ５０の下部に接続される。この場合にも、充放電コネクタ７５が車体後方寄りに配設されていることで、第３ハーネスＨ３の長さが短くて済み、電気抵抗が低減できると共にハーネスの配索作業が簡単になる。ＰＣＵ５０の上部に接続される第１ハーネスＨ１は、車幅方向右側に取り回されてモータＭに接続される第２ハーネスＨ２に連なる。 The third harness H3 connected to the charge / discharge connector 75 is connected to the lower part of the PCU 50 through the left side in the vehicle width direction. Also in this case, since the charging / discharging connector 75 is disposed closer to the rear of the vehicle body, the length of the third harness H3 can be shortened, the electrical resistance can be reduced, and the wiring work of the harness is simplified. The first harness H1 connected to the upper part of the PCU 50 is connected to the second harness H2 that is routed to the right in the vehicle width direction and connected to the motor M.
　また、アーム部４７の後方で傾斜して配設されるＰＣＵ５０を、左右一対のリヤフレームＦ１１に架け渡される下側クロス部材Ｆ１２および上側クロス部材Ｆ１３およびに支持することで、車体フレームＦの剛性を向上させつつ、ＰＣＵ５０を安定的に支持することを可能としている。また、ＰＣＵ５０が発熱した場合でも、クロス部材を介してリヤフレームＦ１１に熱を逃がすことが可能となる。さらに、下側クロス部材Ｆ１２および上側クロス部材Ｆ１３の車体前方側にＰＣＵ５０を配置することで、車体後方側から外力が加えられた際にもＰＣＵ５０を保護することができる。 Further, the rigidity of the vehicle body frame F is supported by supporting the PCU 50 inclined at the rear of the arm portion 47 on the lower cross member F12 and the upper cross member F13 that span the pair of left and right rear frames F11. The PCU 50 can be stably supported while improving the above. Further, even when the PCU 50 generates heat, heat can be released to the rear frame F11 through the cross member. Furthermore, by arranging the PCU 50 on the front side of the vehicle body of the lower cross member F12 and the upper cross member F13, the PCU 50 can be protected even when an external force is applied from the rear side of the vehicle body.
　図１２は、バッテリＢを収納するバッテリ収納部１００の斜視図である。バッテリ収納部１００は、バッテリケース４４の内壁面によって形成される。バッテリ収納部１００を覆って低床フロア１５の大部分を構成する蓋部材１６（図６参照）は、車幅方向両端部に達する形状とされる。バッテリケース４４の車体前方の壁面上部には、蓋部材１６のヒンジ部分を挿入する開口５４ａが設けられている。また、バッテリ収納部１００の車体後方側に位置する支持プレートＦ１４には、蓋部材１６の下面に設けられるフック（不図示）が係合する長穴１０１が形成されている。そして、バッテリケース４４の車幅方向の両壁面には、バッテリＢの着脱作業を容易にするため、車体側面視で山形をなす所定厚さの段差１０２が左右対称形状で設けられている。 FIG. 12 is a perspective view of the battery storage unit 100 in which the battery B is stored. The battery storage unit 100 is formed by the inner wall surface of the battery case 44. The cover member 16 (see FIG. 6) that covers the battery storage unit 100 and constitutes the majority of the low floor 15 is shaped to reach both ends in the vehicle width direction. An opening 54 a for inserting the hinge portion of the lid member 16 is provided in the upper part of the wall surface of the battery case 44 in front of the vehicle body. In addition, a long hole 101 is formed in the support plate F14 located on the vehicle body rear side of the battery storage unit 100 to engage a hook (not shown) provided on the lower surface of the lid member 16. Further, on both wall surfaces of the battery case 44 in the vehicle width direction, a step 102 having a predetermined thickness that forms a mountain shape when viewed from the side of the vehicle body is provided in a bilaterally symmetrical shape in order to facilitate attachment / detachment of the battery B.
　図１３は、バッテリＢを左側後方上方から見た斜視図である。また、図１４はバッテリＢの右側面図である。バッテリＢは、車体側面視で、上面７９および底面８６が互いに平行をなすと共に、前面８７および後面７７が互いに平行をなす横長の直方体とされる。バッテリＢの左右側面８４Ｌ，８４Ｒには、バッテリ収納部１００に形成された段差１０２に係合するバッテリ側段差８５が形成されている。バッテリ側段差８５は、左右側面８４Ｌ，８４Ｒの平面部８２Ｌ，８２Ｒの下方に、車体側面視で山形をなす凹面８３Ｌ，８３Ｒを設けることで形成される。バッテリ側段差８５がなす山形は、車体前方側の傾斜が小さいと共に車体後方側の傾斜が大きい形状とされる。これにより、バッテリＢを収納する際には、バッテリＢの前方側を先に接触させてから前方下方にスライドさせるようにして所定位置に収めることができ、一方、バッテリＢを取り外す際には、バッテリＢの後方側を上方に持ち上げることでバッテリＢを傾斜させることが容易となる。 FIG. 13 is a perspective view of the battery B as viewed from the upper left rear side. FIG. 14 is a right side view of the battery B. The battery B is a horizontally long rectangular parallelepiped in which a top surface 79 and a bottom surface 86 are parallel to each other, and a front surface 87 and a rear surface 77 are parallel to each other in a side view of the vehicle body. On the left and right side surfaces 84 </ b> L and 84 </ b> R of the battery B, a battery side step 85 that engages with the step 102 formed in the battery storage unit 100 is formed. The battery-side step 85 is formed by providing concave surfaces 83L and 83R that form a mountain shape in a side view of the vehicle body below the flat portions 82L and 82R of the left and right side surfaces 84L and 84R. The mountain shape formed by the battery side step 85 has a small inclination on the front side of the vehicle body and a large inclination on the rear side of the vehicle body. Thereby, when storing the battery B, the front side of the battery B can first be brought into contact with the front side and then slid downward in the front, and on the other hand, when removing the battery B, It becomes easy to incline the battery B by lifting the rear side of the battery B upward.
　前記したように、バッテリＢの把手７３は、車体側面視で、バッテリＢを車体に取り付けた際に車体上方後方寄りに位置する角部を含んで車幅方向に指向する棒状とされる。換言すれば、把手７３は、略直方体の角部の近傍に略Ｌ字断面をなす開口７２，７６を設けることで形成されている。これにより、把手７３を把持してバッテリＢを上方に起こす作業が容易となると共に、直方体とされるバッテリＢの外形から把手７３が突出することなく、バッテリ収納部１００の内壁面を簡単な形状とすることができる。バッテリＢの後面７７と底面８６との間の角部には、バッテリ収納部１００の車体後方の壁面との干渉を防ぐための丸面取りが大きく施されている。また、バッテリＢの後面７７には、所定の収納位置でバッテリＢを保持するためのロック部材が係合する係合凹部７８が設けられている。 As described above, the handle 73 of the battery B has a rod-like shape that includes a corner portion that is positioned closer to the rear upper side of the vehicle body when the battery B is attached to the vehicle body when viewed from the side of the vehicle body. In other words, the handle 73 is formed by providing openings 72 and 76 having a substantially L-shaped cross section in the vicinity of a corner portion of a substantially rectangular parallelepiped. This facilitates the work of gripping the handle 73 and raising the battery B upward, and the inner wall surface of the battery housing portion 100 has a simple shape without protruding the handle 73 from the outer shape of the battery B that is a rectangular parallelepiped. It can be. The corner between the rear surface 77 and the bottom surface 86 of the battery B is greatly rounded to prevent interference with the rear wall surface of the battery storage unit 100. The rear surface 77 of the battery B is provided with an engagement recess 78 that engages with a lock member for holding the battery B in a predetermined storage position.
　図１５は、図６の一部拡大図である。シート２６は、車体前方側のヒンジ機構８９を軸にして開閉可能に構成されている。シート２６のシート底板２６ｂの車体後方寄りの位置にはフック８８が設けられており、このフック８８を保持するシートキャッチ機構９０が、収納ボックス８０の後壁の上端部に固定されている。 FIG. 15 is a partially enlarged view of FIG. The seat 26 is configured to be openable and closable around a hinge mechanism 89 on the front side of the vehicle body. A hook 88 is provided at a position near the rear of the vehicle body of the seat bottom plate 26 b of the seat 26, and a seat catch mechanism 90 that holds the hook 88 is fixed to the upper end portion of the rear wall of the storage box 80.
　収納ボックス８０には、車体前方側で略水平をなして最深部を構成する前側底部８０ｂと、車体後方側で略水平をなす後側底部８０ｄと、前側底部８０ｂおよび後側底部８０ｄとの間に位置する傾斜部８０ａとが形成されている。そして、前側底部８０ｂの下面に形成されるボス８０ｃによって、前側底部８０ｂが中間フレームＦ６のボックス固定ステー５９に固定されると共に、後側底部の下面に形成されるボス８０ｅによって、後側底部８０ｄが上側クロス部材Ｆ１３の上板部Ｆ１３ａに固定される。換言すれば、収納ボックス８０は、前側底部８０ｂと後側底部８０ｄによって車体フレームＦに支持されており、シート２６は収納ボックス８０に支持されている。 The storage box 80 includes a front bottom portion 80b that is substantially horizontal at the front side of the vehicle body and forms the deepest portion, a rear bottom portion 80d that is substantially horizontal at the rear side of the vehicle body, and a front bottom portion 80b and a rear bottom portion 80d. And an inclined portion 80a located at the same position. The front bottom 80b is fixed to the box fixing stay 59 of the intermediate frame F6 by the boss 80c formed on the lower surface of the front bottom 80b, and the rear bottom 80d is formed by the boss 80e formed on the lower surface of the rear bottom.

In other words, the storage box 80 is supported by the vehicle body frame F by the front bottom 80b and the rear bottom 80d, and the seat 26 is supported by the storage box 80.
　これにより、収納ボックス８０を強度部材として用いてシート２６にかかる荷重を収納ボックス８０が受け止める構成とすることで、収納ボックス８０の側方までフレーム部材を伸ばす必要がなくなり、車体フレームＦの後部を簡略化して軽量化を図ると共に、収納ボックス８０の容量を拡大することが可能となる。また、この構成により、リヤフレームＦ１１の後端部７１がテールライト６０より車体前方に位置することとなり、短いリヤフレームＦ１１によって軽量化が図られると共に、車体後方側の重量を低減してマスの集中を図ることを可能としている。 As a result, the storage box 80 is used as a strength member so that the load applied to the seat 26 is received by the storage box 80, so that it is not necessary to extend the frame member to the side of the storage box 80. In addition to simplification and weight reduction, the capacity of the storage box 80 can be increased. In addition, with this configuration, the rear end portion 71 of the rear frame F11 is positioned in front of the vehicle body with respect to the taillight 60, and the weight is reduced by the short rear frame F11. It is possible to concentrate.
　さらに、収納ボックス８０を車体フレームＦに固定することでＰＣＵ５０が傾斜部８０ａの車体後方側に近接配置されることとなり、傾斜したリヤフレームＦ１１にＰＣＵ５０を支持させつつ、収納ボックス８０の容量を確保することが可能となる。加えて、収納ボックス８０の底部の少なくとも一部が、リヤクッション７０の車体前方側の軸支部７０ｂと車体後方側の軸支部７０ａとの間に配設されることで、収納ボックス８０とリヤクッション７０とが近接配置されて、収納ボックスに収められた荷物がリヤクッションに近い位置に配設されることとなり、マスの集中を図る効果が維持されやすくなる。 Further, by fixing the storage box 80 to the vehicle body frame F, the PCU 50 is disposed close to the vehicle body rear side of the inclined portion 80a, and the capacity of the storage box 80 is secured while the PCU 50 is supported by the inclined rear frame F11. It becomes possible to do. In addition, at least a part of the bottom portion of the storage box 80 is disposed between the shaft support portion 70b on the vehicle body front side and the shaft support portion 70a on the vehicle body rear side of the rear cushion 70, whereby the storage box 80 and the rear cushion are arranged. 70 and the baggage stored in the storage box are arranged at a position close to the rear cushion, and the effect of concentrating the mass is easily maintained.
