Description

  The present invention relates to a vehicle sealing cover pasting structure for closing a plurality of holes by sticking one sealing cover to a sheet metal panel having a plurality of holes with a waterproof adhesive.

  A plurality of holes are formed in a sheet metal panel that forms a vehicle body of a vehicle such as an automobile or a surface on the indoor side of a door for work, weight reduction, or attachment of parts. For example, FIG. 5 shows a longitudinal section of the vehicle door 103, and holes 108 and 109 are formed in the inner panel 106 on the indoor side of the vehicle door 103, and the vehicle body and the door are formed from these holes 108 and 109. If water or dust enters inside 103, the functions of the vehicle body and door 103 may be impaired. Therefore, a plurality of holes 108 and 109 are closed by sticking a sealing cover 111 such as a vinyl sheet to the inner panel 106 with a waterproof adhesive 112 or 113 such as butyl tape.

By the way, Patent Document 1 proposes a vehicle seal structure in which a protrusion is provided around the trim clip hole of the panel toward the inside of the vehicle body, and the sealing cover is aligned by this protrusion. .
