Description

  TECHNICAL FIELD The present invention relates to a drainage structure for an open car having an openable and closable roof, and a back wind disposed at the rear of the roof also rotating.

Conventionally, as shown in FIG. 7, when the roof 1 is openable and closable, and when the roof 1 is changed from a closed state (FIG. 7A) to an open state (FIG. 7B), the roof 1 is disposed at a rear portion of the roof 1. There is known an open car in which a back window 2 can be rotated together with a roof 1 and stored in a trunk room 3 behind the vehicle.
As shown in FIG. 8, a back window weatherstrip 5 is attached to an outer peripheral edge of the back window 2, and elastically contacts a lid panel 4 that covers the roof 1 and the trunk room 3 to seal the inside and outside of the vehicle.
However, since the back window 2 rotates when the roof 1 is opened and closed, even if the back window weather strip 5 is attached to the outer peripheral edge of the back window 2, the sealing property at the lower left and right corners of the back window 2 is problematic. become.

Therefore, a structure is disclosed in which a drain hole is formed in the back window weatherstrip 5 to drain water W due to rainfall or car washing flowing along the groove of the back window weatherstrip 5 from the drain hole to the outside of the vehicle. (For example, Patent Documents 1 and 2).
The invention described in Patent Literature 1 provides a hole in a hollow seal portion of a weather strip located in a gap between a roof and a back window, guides water transmitted in the groove into the hollow seal portion, and provides the water at a terminal portion. The water is drained out of the vehicle through a drain port.
Further, the invention described in Patent Document 2 provides a weather strip provided at the lower part of the back window with a collecting gutter and a flexible hose connected to the collecting gutter so that transmitted water is discharged to the side window side. It was done.
