根據第1發明,於前輪及/或前擋泥板之側面配置電池之至少一部分,且以其後部配置於較其前部更靠車寬方向內側之方式使電池於車體前後方向產生傾斜,且藉由以避免干擾 前輪或前擋泥板之方式來配置,藉此可使電池於車輛前後方向加以延伸而一方面使其容量增大,一方面可極力抑制車輛前部之寬度尺寸,又,由於在車輛前部配置電池,故而可確保乘坐者之空間為較大。 According to the first aspect of the invention, at least a part of the battery is disposed on the side surface of the front wheel and/or the front fender, and the battery is inclined in the front-rear direction of the vehicle body such that the rear portion thereof is disposed on the inner side in the vehicle width direction from the front portion. And by avoiding interference The front wheel or the front fender is configured in such a manner that the battery can be extended in the front-rear direction of the vehicle and the capacity thereof can be increased on the one hand, and the width dimension of the front portion of the vehicle can be suppressed as much as possible on the one hand, and at the front of the vehicle. The battery is configured so that the space for the occupant is large.
又,於跨坐型電動車輛中,存在稱作搖晃(weave)之後輪在組合於偏轉及滾轉方向而產生搖擺之現象,該搖晃容易產生於後輪承載負荷較高時。針對此,於本發明中,作為重量物品之電池配置於車體前部,因此與於車體後部配置電池之情形相比可降低後輪之振動。 Further, in the straddle type electric vehicle, there is a phenomenon in which the wheel is combined in the yaw and roll directions to cause sway after the weave, and the sway is likely to occur when the rear wheel load is high. In contrast, in the present invention, since the battery as the weight item is disposed in the front portion of the vehicle body, the vibration of the rear wheel can be reduced as compared with the case where the battery is disposed at the rear of the vehicle body.

根據第3發明,藉由使電池靠近前輪而使前輪之分擔負荷提高,從而可更確實地降低後輪之振動。 According to the third aspect of the invention, the load of the front wheels is increased by bringing the battery closer to the front wheels, so that the vibration of the rear wheels can be more reliably reduced.
於跨坐型車輛中,存在有被稱為擺振之前輪在繞著轉向軸產生小幅搖擺之現象,容易產生於前輪承載負荷較高時。本發明者等人經過銳意研究之結果發現,將重量物品配置於連結頭管及後輪之接地點之直線上則不易產生擺振。因此,根據第4發明,亦可有效地抑制前輪之振動。 In the straddle type vehicle, there is a phenomenon that the front wheel is slightly swayed around the steering shaft when it is called a shimmy, which is likely to occur when the front wheel load is high. As a result of intensive research, the inventors of the present invention found that it is difficult to generate a shimmy when a weight article is placed on a straight line connecting the grounding points of the head pipe and the rear wheel. Therefore, according to the fourth invention, the vibration of the front wheels can be effectively suppressed.

根據第6發明,於在屬於下行框架部之後方且下框架部之 上方形成乘坐者之跨腳空間之情形時,可確保該跨腳空間為較大。 According to the sixth invention, after belonging to the downstream frame portion and the lower frame portion When the occupant's foot space is formed above, it is ensured that the foot space is large.
根據第7發明,一方面可使電池之冷卻性良好且一方面可削減零件件數。 According to the seventh aspect of the invention, on the one hand, the cooling property of the battery can be improved, and on the other hand, the number of parts can be reduced.
