| 主权项 | 1. A lid member with a waterproofing function for opening and closing an opening portion formed in a housing, the lid member comprising: a resin main body accommodated in said opening portion; a projection portion which is integrally formed in one surface of said resin main body, said projection portion having a distal end surface and an outer peripheral surface; and an elastic seal portion which is integrally formed in said outer peripheral surface of said projection portion, said seal portion including an annular projection configured to abut an inner peripheral surface of said opening portion, wherein said annular projection is formed as a shape which is expanded toward an inner portion side of said housing in said opening portion, has a tapered outer peripheral surface which converges toward said inner portion side, and is provided with a seal surface having a circular arc shaped cross section extending from said tapered outer peripheral surface toward said resin main body, and wherein a maximum diameter of said seal surface is positioned closer to said inner portion side of said housing than said distal end surface. | ||
