Further, an exhaust port 32c is attached to the rear surface of the casing 32, and the exhaust port 32c communicates with an extractor chamber (not shown) that exhausts air in the vehicle compartment 2.

  With such a configuration, a part of the outside air introduced into the vehicle 1 by the blower portion 21a is not used for generating conditioned air such as cooling air or hot air, and the housing directly passes through the auxiliary duct 34. The air is blown toward the capacitor 30 and the DC-DC converter 31 in 32, and then exhausted to the outside of the vehicle through the exhaust port 32c and the extractor chamber.

  By the way, in the present embodiment, the capacitor 30 and the rear seat air conditioning unit 21 as the power supply device are disposed behind the rear wheel house 16 above the rear part of the floor pan 7, and as shown in FIG. As shown in FIGS. 3 and 5, the rear seat air-conditioning unit 21 and the capacitor 30 are prevented from entering the vehicle compartment 2 by being disposed so as to be located outside the house inner lower portion 26a of the house 16 in the vehicle width direction. The rear side trim 24 can be formed flat along the housing 32 (capacitor 30) and the rear wheel house 16 (house inner lower portion 26a).

  Thus, by forming the rear side trim 24 in a flat shape, the unevenness on the rear side surface of the passenger compartment 2 can be reduced, and the appearance can be ensured.

  Furthermore, by arranging the capacitor 30 and the rear seat air conditioning unit 21 at a position overlapping the rear wheel house 16 in a side view, it is possible to secure a wide space in the rear front side of the passenger compartment 2. .

Can be cooled.

  Further, when the capacitor 30 is disposed at the rear portion of the vehicle 1, the arrangement position is taken into consideration so that the behavior of the capacitor 30 at the rear collision of the vehicle 1 does not affect the passengers in the passenger compartment 2. However, in this embodiment, since the capacitor 30 is disposed on the side surface of the passenger compartment 2, the influence at the time of a rear collision of the vehicle 1 can be prevented.

  Further, by disposing the capacitor 30 on the inner side in the vehicle width direction of the rear seat air conditioning unit 21, the capacitor 30 can be easily accessed from the vehicle compartment 2 side by removing the rear side trim 24 from the vehicle body. For this reason, when the necessity for the maintenance of the capacitor 30 arises, the maintenance of the capacitor 30 can be easily performed.

  In addition, the capacitor 30 and the DC-DC converter 31 are disposed in the vehicle front-rear direction and are disposed on the same plane on the inner side in the vehicle width direction, so that the capacitor 30 and the DC-DC converter 31 are disposed. Even if it is arranged at the rear part of the vehicle compartment 2, as shown in FIGS. 3 and 5, while the rear side trim 24 is formed flat, the intrusion of the DC-DC converter 31 into the vehicle compartment 2 is suppressed. A wide space in front of the rear part of the chamber 2 can be secured.

  Further, the capacitor 30 and the DC-DC converter 31 are integrally disposed in the housing 32, so that they can be easily assembled to the vehicle body.

  Further, by connecting the capacitor 30 and the like of the regenerative power system unit 17 to the rear seat air conditioning unit 21 via the auxiliary duct 34, the capacitor 30 is cooled using the air blown from the rear seat air conditioning unit 21. In this embodiment, the capacitor 30 can be cooled using a part of the outside air introduced by the blower portion 21a.

  In addition, by connecting the auxiliary duct 34 to the blower portion 21a, not the conditioned air used for the passengers in the third row seat 6, but a part of the outside air before the conditioned air is generated is directly used as the capacitor 30 or the like. Can be supplied. For this reason, the air volume of the conditioned air supplied toward the occupant can be secured, and the air conditioning function of the rear seat air conditioning unit 32 can be secured.

  In addition, since the cooler duct 19 and the auxiliary duct 34 are separated, for example, it is possible to prevent inconvenience that hot air after cooling the capacitor 30 flows backward and is supplied to the cooler duct 19. For this reason, it can prevent more reliably that the air conditioning function of the rear seat air conditioning unit 32 falls.

  However, the present invention is not necessarily limited to cooling the capacitor 30 by supplying outside air as it is. In the case where the air conditioning function of the rear seat air conditioning unit 32 is not greatly affected, for example, a branch duct may be provided in a part of the cooler duct 19 and the branch duct may be connected to the capacitor 30.

  Further, by arranging the rear seat air conditioning unit 21 and the capacitor 30 behind the rear wheel house 16, a space can be formed in the side part of the rear front side of the passenger compartment 2. For this reason, in this embodiment, the step part 24a is formed in the rear side trim 24 between the quarter window 15 and the rear wheel house 16, and the recessed part 24b can be provided in a part thereof.

  Thus, by providing the recessed portion 24b above the rear wheel house 16, the recessed portion 24b is used as a cup holder for positioning a cup CU such as a container for drinking water as shown in FIG. 6, for example. Or can be used as an accessory case.
