如此，在具备配置于车身前部及车身后部中的一方的发动机14、将发动机14的输出传递至配置于车身前部及车身后部中的另一方的车轮12R的传动轴30、以及设置为可通过传动轴30驱动并且支持于车身10的发电机的车辆中，可通过将该传动轴30的车身前后方向的中央部支持于发电机以此通过发电机将传动轴30支持于车身10。
该情况下，在具备在车身前后方向上延伸的传动轴的车辆中，能够经由支持于车身的发电机使传动轴支持于车身，因此与使传动轴和发电机分别支持于车身的情况相比，能够简化相对于车身的传动轴的支持结构。又，由于传动轴的车身前后方向的中央部受到支持，以此能够稳定的支持传动轴。
第一实施形态的混合动力车10是以前置引擎・前轮驱动车为基础的四轮驱动车，但也可以在以前置引擎・后轮驱动车为基础的的四轮驱动车中，同样地通过驱动马达使传动轴支持于车身。

车身10´也与车身10同样地，驱动马达40配置于传动轴30´的车身前后方向的中央部上，具体而言配置于后传动轴30´的车身前后方向的中央部上。通过使传动轴30´的车身前后方向的中央部支持于驱动马达40，以此使传动轴30´通过驱动马达40支持于车身10´。
本实施形态中，对于具备配置于车身前部的发动机14、将发动机14的输出传递至后轮12R的传动轴30´、和设置为能驱动传动轴30´并支持于车身10´的驱动马达40的混合动力车10´，使传动轴30´支持于驱动马达40从而通过驱动马达40支持于车身10，但亦可对于具备配置于车身后部的发动机、将发动机的输出传递至前轮的传动轴、和设置为能驱动传动轴并且支持于车身的驱动马达的混合动力车，同样地使传动轴支持于驱动马达从而通过驱动马达支持于车身。
又，第二实施形态的混合动力车10´是以前置引擎・后轮驱动车为基础的四轮驱动车，但亦可对于发动机配置于车身前部并将发动机的输出向配置于车身后部的车轮传递的前置引擎・后轮驱动的二轮驱动车，同样地使传动轴支持于驱动马达从而通过驱动马达支持于车身。
如此，本实施形态的混合动力车10´也具备配置于车身前部及车身后部中的一方的发动机14、将发动机14的输出向配置于车身前部及车身后部中的另一方的车轮12R传递的传动轴30´、和设置为能驱动传动轴30´并且支持于车身10的驱动马达40，传动轴30´通过使车身前后方向的中央部支持于驱动马达40以此通过驱动马达40支持于车身10´。
由此，在具备在车身前后方向延伸的传动轴30´的混合动力车10´中，能够通过支持于车身10´驱动马达40使传动轴30´支持于车身10´，与使传动轴和驱动马达分别支持于车身的情况相比，能够简化相对于车身10´的传动轴30´的支持结构。又，由于传动轴30´的车身前后方向的中央部受到支持，因此能够稳定地支持传动轴30´。
本实施形态中，在具备在车身前后方向上延伸的传动轴30´的混合动力车10´中，通过使传动轴30´的中央部支持于驱动马达40以此使传动轴30´通过驱动马达40支持于车身10´，但亦可取代驱动马达40，在具备发电机的车辆中，通过使传动轴支持于发电机以此通过发电机支持于车身。
在上述实施形态中，传动轴中，传动轴的车身前后方向的中央部受到支持，但亦可对从传动轴的车身前后方向中央部向车身前侧或车身后侧偏移的部分进行支持，可以在能够稳定地支持传动轴的范围内，对包含从传动轴的车身前后方向中央部向车身前侧或车身后侧偏移的部分的、传动轴的车身前后方向的大致中央部进行支持。
本发明并非限定于所例示的实施形态，可以在不脱离本发明的主旨的范围内，进行各种改良及设计上的变更。
工业应用性：
如以上，根据本发明，在具备传动轴的混合动力车等车辆中，能够简化相对于车身的传动轴的支持结构，因此可良好利用于该种车辆的制造产业领域。
