a synthetic resin film for joining the sheet body to the door inner panel, the synthetic resin film being transparent, the synthetic resin film including: an internal circumferential end which sticks to the sheet body; and an outer circumferential end which sticks to an inner-cabin side of the door inner panel by adhesive; and a sheet separation provided at a distance from the sheet body and between an outer circumferential end of the sheet body and the outer circumferential end of the synthetic resin film, the sheet separation adhering to the synthetic resin film. ## Claims ### Claim 1 A door hole seal comprising: a sheet body configured to operably couple to a door inner panel for covering an opening on said door inner panel; a synthetic resin film for joining the sheet body to the door inner panel, said synthetic resin film being transparent or semitransparent, the synthetic resin film including: an internal circumferential end which sticks to said sheet body; and an outer circumferential end which sticks to an inner-cabin side of said door inner panel by adhesive; and a sheet separation provided at a distance from said sheet body and between an outer circumferential end of said sheet body and the outer circumferential end of said synthetic resin film, the sheet separation adhering to said synthetic resin film; wherein a plurality of said sheet separations are provided along a curve and at a distance from each other, the curve encircling the sheet body as a whole. ### Claim 2 (depends on 1) The door hole seal as claimed in claim 1, wherein said sheet separation extends in a direction that said curve extends. ### Claim 3 (depends on 2) The door hole seal as claimed in claim 2, wherein said sheet separation protrudes toward an outer side from the outer circumferential end of said synthetic resin film. ### Claim 4 (depends on 3) The door hole seal as claimed in claim 3, wherein the outer circumferential end of said synthetic resin film includes a cutout between the sheet separations adjacent to each other along said curve, the cutout facing the internal circumferential end. ### Claim 5 (depends on 1) The door hole seal as claimed in claim 1, wherein said adhesive is provided between the outer circumferential end of said sheet body and said sheet separation, the adhesive encircling said sheet body as the whole. ### Claim 6 (depends on 2) The door hole seal as claimed in claim 2, wherein said adhesive is provided between the outer circumferential end of said sheet body and said sheet separation, the adhesive encircling said sheet body as the whole. ### Claim 7 (depends on 3) The door hole seal as claimed in claim 3, wherein said adhesive is provided between the outer circumferential end of said sheet body and said sheet separation, the adhesive encircling said sheet body as the whole. ### Claim 8 (depends on 4) The door hole seal as claimed in claim 4, wherein said adhesive is provided between the outer circumferential end of said sheet body and said sheet separation, the adhesive encircling said sheet body as the whole. ### Claim 9 (depends on 1) The door hole seal as claimed in claim 1, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 10 (depends on 2) The door hole seal as claimed in claim 2, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 11 (depends on 3) The door hole seal as claimed in claim 3, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 12 (depends on 4) The door hole seal as claimed in claim 4, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 13 (depends on 5) The door hole seal as claimed in claim 5, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 14 (depends on 6) The door hole seal as claimed in claim 6, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 15 (depends on 7) The door hole seal as claimed in claim 7, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 16 (depends on 8) The door hole seal as claimed in claim 8, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 17 A door hole seal comprising: a sheet body configured to operably couple to a door inner panel for covering an opening on said door inner panel; a synthetic resin film for joining the sheet body to the door inner panel, said synthetic resin film being transparent or semitransparent, the synthetic resin film including: an internal circumferential end which sticks to said sheet body; and an outer circumferential end which sticks to an inner-cabin side of said door inner panel by adhesive; and a sheet separation provided at a distance from said sheet body and between an outer circumferential end of said sheet body and the outer circumferential end of said synthetic resin film, the sheet separation adhering to said synthetic resin film; wherein said adhesive is provided between the outer circumferential end of said sheet body and said sheet separation, the adhesive encircling said sheet body as a whole. ### Claim 18 (depends on 17) The door hole seal as claimed in claim 17, wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer. ### Claim 19 A door hole seal comprising: a sheet body configured to operably couple to a door inner panel for covering an opening on said door inner panel; a synthetic resin film for joining the sheet body to the door inner panel, said synthetic resin film being transparent or semitransparent, the synthetic resin film including: an internal circumferential end which sticks to said sheet body; and an outer circumferential end which sticks to an inner-cabin side of said door inner panel by adhesive; and a sheet separation provided at a distance from said sheet body and between an outer circumferential end of said sheet body and the outer circumferential end of said synthetic resin film, the sheet separation adhering to said synthetic resin film; wherein said sheet separation comprises a foamed rubber-like elastic body and an outer circumferential surface of the sheet separation except for an outer-cabin side surface and an inner-cabin side surface is ineffective in comprising a skin layer.
