As shown in FIG. 1, the vehicle A includes a slide door 20 on the side surface on the rear seat side. A rocker portion 30 is formed on the side surface of the vehicle A so as to extend in the front-rear direction along the lower edge. Further, as shown in FIG. 2, the rocker portion 30 is configured by combining an outer panel 32 and an inner panel 34. The rocker portion 30 is installed in such a posture that the outer panel 32 faces the outside of the vehicle and the inner panel 34 faces the center in the vehicle width direction.

  Moreover, in the locker part 30, the door pocket part 50 is provided in the side (back seat side) in which the slide door 20 was provided. The door pocket portion 50 has an outer shape that is open toward the outside of the vehicle A and has a substantially “U” cross-sectional shape. A guide rail 52 for supporting and guiding the lower end portion of the slide door 20 is installed inside the door pocket portion 50.

  The door pocket part 50 is extended toward the vehicle width direction center side rather than the inner panel 34 which makes the locker part 30 mentioned above. In other words, the door pocket vertical wall 54 erected on the back side when viewed from the opening side of the door pocket portion 50 exists on the vehicle width direction center side with respect to the inner vertical wall 36 forming the inner panel 34.

  A drain hole 60 is provided in the bottom surface 56 of the door pocket portion 50 and in a region on the back side of the position where the inner vertical wall 36 is provided (hereinafter also referred to as “back side region 58”). In the present embodiment, the drain hole 60 is provided at a position adjacent to the door pocket vertical wall 54.

A drain pipe 62 is connected to the drain hole 60. Drainage tube 62 has a funnel-shape of the external shape, a tube used for discharging from the door pocket 50 collects waste water collected in the drain hole 60. The drain pipe 62 is provided so as to protrude downward from the bottom surface 56 of the door pocket portion 50.

A floor panel 70 is provided below the locker portion 30 and the door pocket portion 50 described above with a space from the bottom surface 56 of the door pocket portion 50 . A member member 80 is attached to the lower surface 72 side of the floor panel 70.
