And a flange 21 extending in the horizontal direction from the lower end edge of the entire surface (see FIGS. 2 and 7).

  As shown in FIGS. 10 and 11, the height of the lid 2 is set so as to follow the shape of a seating portion 9a of the rear seat 9 described later. Specifically, the ceiling portion 22 of the lid 2 is divided into two parts in the front-rear direction and three parts in the left-right direction in a top view, and the first region 60A is counterclockwise from the front right side of the vehicle. The region is divided into six regions: a second region 60B, a third region 60C, a fourth region 60D, a fifth region 60E, and a sixth region 60F.

  The three first to third regions 60A, 60B, 60C on the front side are formed higher than any of the four fourth to sixth regions 60D, 60E, 60F on the rear side. The ceiling portion 22 of the three first to third regions 60A, 60B, 60C on the front side is slightly higher than the height of the first region 60A and the third region 60C on the left and right sides of the center second region 60B.

The second region 60B located in the center is lower than the first region 60A and the third region 60C on the left and right sides provided with the high-voltage electrical equipment cover 26 and the intake cover 25. That is, the heights of the uppermost portions of the first to third regions 60A, 60B, and 60C are the first region 60A provided with the high-voltage electrical equipment cover 26, the third region 60C provided with the intake cover 25, and the second region. It becomes lower in order of 60B (see FIG. 14). The first region 60A and the third region 60C may be the same height, and the third region 60C may be higher than the first region 60A.

  On the other hand, the four fourth to sixth regions 60D, 60E, and 60F on the rear side are formed so that the height of the fifth region 60E located in the center is high, and the fourth region 60D and the sixth region 60F on the left and right sides thereof are The lowest and the same height. That is, the height of the uppermost part of each region is the fourth region 60D and the sixth region 60F <the fifth region 60E <the second region 60B <the third region 60C <the first region 60A in ascending order.

  The ceiling portion 22 of the three fourth to sixth regions 60D, 60E, 60F on the rear side is an inclined surface whose height decreases toward the rear of the vehicle, and the fifth region 60E in the center is the fourth on both the left and right sides. Since the height is higher than the region 60D and the sixth region 60F, the vertical wall 22a is between the fifth region 60E, the fourth region 60D, the fourth region 60D, and the fourth region 60D. It is formed continuously in the sixth region 60F.

  That is, the height of the uppermost part of the lid 2 is such that the three fourth to sixth regions 60D, 60E, 60F on the rear side are more than the three first to third regions 60A, 60B, 60C on the front side. Of the three fourth to sixth regions 60D, 60E, 60F on the rear side, the left and right fourth regions 60D and the sixth region 60F are lower than the fifth region 60E located in the center. .
