The front portion of the seat cushion casing 49 that covers the power driving unit casing 74 and the power driving unit 70 from the front and the left and right sides is provided with a plurality of openings 96, 96 extending in the vehicle width direction at intervals. Further, in the seat cushion casing 49, a plurality of blades 97, 97, ... extending from the upper edge of each of the openings 96, 96, ... are integrally provided. In the lower housing chamber 81 of the power driving unit casing 74, a lead storage battery, that is, a low voltage battery 98, is housed and fixed so as to be disposed between the pair of left and right seat cushion frames 19 and 19 below the power driving unit 70. . On the other hand, the Li-ion battery, that is, the high-voltage battery 99, as shown in Fig. 1, is disposed on the left side of the rear wheel WR, and is housed and fixed in the battery case 100, and the battery case 1 is placed on the seat frame 19. Supported. Next, the operation of this embodiment will explain that the oil tank 46 for storing the fuel supplied to the engine E is a pair of left and right seat cushion frames disposed in the vehicle body frame F for supporting the passenger seat cushion 47. Between the rear portions of 19..., the motor drive unit 70 that drives the motor Μ is driven, at least a portion (most of which is in this embodiment) is disposed in the two-seat frame 19, 19 as viewed from a plan view. Between the front side of the fuel tank 46 and the front portion of the passenger seat cushion 47 and the seat cushion frame 19, the power is covered from the front and left and right sides. -19·201111205 The front portion of the seat cushion casing 49 of the drive unit 70 is provided with openings 96 and 96 that guide the traveling gas toward the power drive unit 70 side. Therefore, the fuel tank 46 is disposed with good weight balance. The power driving unit 70, and since the traveling airflow from the opening portions 96, ... provided at the front portion of the seat cushion casing 49 is guided toward the power driving unit 70 side, the power driving unit 70 is efficiently cooled. The plurality of openings 96, 96, ... are disposed at intervals in the vertical direction and extend in the vehicle width direction, and are provided in front of the seat cushion casing 49. Therefore, it is easy to bring the traveling airflow into contact with the entire power driving unit 70, thereby improving Cooling effect. Further, a plurality of blades 97, 97, ... extending forward from the upper edges of the respective opening portions 96, 96, ... are connected to the seat cushion casing 49, and the traveling airflow can be rectified by the blades 97, 97, ... and the rainwater can be prevented from entering. The seat cushion is located inside the housing 49. On the lower surface of the power driving unit 70, a plurality of cooling blades 8 3 , 8 3 ... spaced apart in the vehicle width direction are protruded so as to extend in the front-rear direction, so that the power can be increased by the respective cooling blades 8 3 , 8 3 . The cooling efficiency of the drive unit 70 is driven, and the traveling airflow from the side is rectified by the respective cooling blades 83, 83... so that the cooling effect can be further improved. A bracket 85 that is coupled to the main frame 17 of the vehicle body frame F and supports the power driving unit 70 is disposed to extend upward in front of the power driving unit 70. The upper end portion of the bracket 85 is provided to rotatably support the vehicle. Since the hinge mechanism 91 of the seat cushion 47 is used, the power drive unit 70 and the passenger seat cushion 47 are supported by the common bracket 85, which contributes to the reduction in the number of pieces. The flow energy and 96 have a fitting and can reach the Yanyuan Qianyuan lower branch -20- 201111205 Between the power drive unit 70 and between the pair of left and right seat cushion frames 19, a low-voltage battery is arranged. 8, so the low voltage battery 98 is disposed under the power drive unit 70 and between the two pad frames 19..., the power drive unit 70 and the fuel tank 46, by the weight of the low voltage battery 98 It is placed in the center of the vehicle width direction to improve the balance. The power driving unit 70 is housed and fixed to the power driving unit casing 74, and the wind between the power driving unit casing 74 and the power driving unit 70 is configured to circulate the traveling airflow from the opening portions 9 6 ', 9 6 . 82. The power drive unit casing 74 is supported by the vehicle body frame F, and a better cooling efficiency for the power drive unit 70 can be achieved. The actuator 42 for opening and closing the throttle valve 39 provided in the intake device 34 provided in the engine E is configured to detect the acceleration position sensor 7 1 of the occupant's door operation amount by The accelerator drive 72 is actuated, and a drive motor 配置 is disposed on the right side in the width direction of the vehicle body frame F. In contrast, the actuator 42, the acceleration position sensor, and the throttle actuator 72 are disposed on the left side in the width direction of the vehicle body frame F. In order to reduce the influence of the magnetic field of the drive motor 对 on the actuator 42, the acceleration position sensor 71 and the throttle actuator 72. Further, the acceleration position sensor 71 and the accelerator actuator 72 disposed above the lower edge of the main frame 17 of the vehicle body frame F are supported from the side, and are supported by the left side surface of the main frame 17 so that the driving of the motor can be effectively suppressed. The influence of the magnetic field on the acceleration position sensor 71 and the throttle actuator 72. In addition to the amount of the internal path, the valve oil is moved to a passive position of 21 1 - 201111205. The power drive unit 70 for driving the drive motor 配置 is disposed in the center of the vehicle width direction and supported by the vehicle body frame F. The high-voltage wiring 95 that is disposed on the right side in the vehicle width direction from the power drive unit 70 and disposed on the right side in the vehicle width direction in the direction in which the drive motor 配置 is disposed is connected to the drive motor Μ, so that wiring and power transmission can be achieved. It is efficient, and noise from high-voltage wiring can be prevented from affecting the acceleration position sensor 71 and the throttle driver 72. A drive motor 配置 is disposed on the right side in the width direction of the vehicle body frame F, and the generator 52 is disposed on the left side in the width direction, and the center of gravity 107G of the starter motor 107 disposed above the crankcase 27 is opposite to the center line of the vehicle body. The CL bias is disposed on the other side in the width direction of the vehicle body frame F (opposite side of the drive motor )), so that the left and right weight balance can be adjusted. The center of gravity 42G of the actuator 42 and the center of gravity 107G of the starter motor 107 are disposed further inside than the outer end of the generator casing 55 in the vehicle width direction, and it is preferable to focus the center of gravity 42G of the actuator 42 and Since the center of gravity 1 07G of the starter motor 107 is disposed in the width of the main frame 17 of the vehicle body frame F as viewed from the plan view, the weight balance of the right and left sides can be considered, and the mass can be concentrated in the center of the vehicle in the vehicle width direction. The embodiments of the present invention have been described above, and the present invention is not limited to the above embodiments, and various design changes can be made without departing from the invention described in the claims.
