Patent number: 7066527Abstract: There is provided a door structure of an automobile, capable of being visually checked as to whether or not a peripheral edge of an opaque water/noise isolation sheet is reliably bonded to a door inner panel through the intermediary of a sealer (adhesive). With the door structure, the door inner panel of the automobile is provided with the opaque water/noise isolation sheet for ensuring watertightness and noise isolation after stopping up at least access holes of the door inner panel, and the inner peripheral edge of a transparent film substantially annular in shape is fixedly attached to the outer peripheral edge of the opaque water/noise isolation sheet, thereby forming a structure wherein the outer peripheral edge of the transparent film is bonded to the door inner panel through the intermediary of the sealer (adhesive).Type: GrantFiled: December 14, 2005Date of Patent: June 27, 2006Assignees: Nishikawa Rubber Co., Ltd., Honda Giken Kogyo Kabushiki KaishaInventors: Yoshihiro Kohara, Shinichiro Emori, Masami Isobe
