  Next, the attachment procedure and operation of the vehicle drainage structure of the present embodiment will be described. FIG. 3 is a cross-sectional view taken along the line AA in FIG. 4 and shows the operation when the flange is attached.

  The procedure for forming the drainage structure of the present embodiment is as follows. First, the drain cover 101 is fixed so that the drain pipe 121 is passed through the opening 1a provided in the floor 1 of the vehicle. At this time, the side drain cover 111 is also fixed to the vehicle (side panel 401). Then, the roll bar unit 201 as a vehicle constituent member is fixed (assembled) to the floor portion 1 of the vehicle adjacent to the drain cover 101 by an attaching flange 202 with a fixing means such as a bolt.

  In FIG. 3, the movement of the mounting flange 202 and the displacement of the bulging portion 104 when the roll bar unit 201 is assembled to the floor portion 1 of the vehicle are indicated by broken lines. The mounting flange 202 is moved downward in the vertical direction from the upper position indicated by the broken line 202 ′, and is disposed on the floor of the vehicle. At this time, the right end portion of the flange 202 pushes the bulging portion 104 from above. Here, as described above, the receiving portion 104a formed in the bulging portion 104 is inclined in the bulging direction and downward of the vehicle. Therefore, by this pressing force, the bulging portion 104 is smoothly displaced to the right as indicated by a broken line 104 ′ in accordance with the displacement of the easily displacing portion 105 provided in the vicinity. For this reason, the workability of assembling the flange 202 is improved, and damage to the bulging portion 104 can be prevented.

  When the flange 202 reaches the vicinity of the vehicle floor 1 while deforming the bulging portion 104 by pressing, there is no pressing force applied to the receiving portion 104a of the bulging portion 104, and the bulging portion 104 is displaced in the reverse direction by the restoring force. And return from the position of the broken line 104 'to the original position (solid line 104). When the assembly of the roll bar unit 201 is finished and a part of the roof (middle roof) 301 is stored, the end portion of the middle roof 301 is located inside the bulging portion 104 as shown in the figure. For this reason, when the middle roof 301 is stored, the water falling from the end thereof can be received by the drain cover 101 and discharged outside the vehicle.

  As described above, according to the present embodiment, even when the roll bar unit 201 is disposed adjacent to the drain cover 101, the vertical wall on the roll bar unit 201 side bulges outward. Since the protruding portion 104 is provided, and an easy-displacement portion 105 that facilitates displacement of the bulging portion 104 with respect to the roll bar unit 201 is provided in the vicinity of the bulging portion 104, the roll bar unit is assembled.
