Vehicle component and sealing member

Abstract

A vehicle component includes a sealing member that is sandwiched between the vehicle component and a vehicle body to seal a gap between the vehicle component and the vehicle body. The sealing member includes an adhering/separating member that is adhereable to and separable from a wall of the vehicle body, and an elastic compressing member that is elastically compressible and stacked on the adhering/separating member. The adhering/separating member adheres to the wall of the vehicle body when the sealing member is present between the vehicle component and the vehicle body.

Claims

1. A vehicle component comprising: a sealing member that is located between the vehicle component and a vehicle body to seal a gap between the vehicle component and the vehicle body, whereinthe sealing member includes a first sealing member that is adhereable to and separable from a wall of the vehicle body, and a second sealing member that is elastically compressible and stacked on the first sealing member, andthe first sealing member adheres to the wall when the sealing member is present between the vehicle component and the vehicle body.

2. The vehicle component according to claim 1, wherein the first sealing member is made of non-vulcanized rubber.

3. The vehicle component according to claim 1, wherein the first sealing member is made of a plastic material.

4. The vehicle component according to claim 1, wherein the first sealing member is made of a non-permeable material.

5. The vehicle component according to claim 1, wherein the first sealing member is made of any one of butyl rubber, ethylene-propylene rubber, and a mixture of butyl rubber and ethylene-propylene rubber.

6. The vehicle component according to claim 1, wherein the first sealing member is made of any one of butyl rubber, ethylene-propylene rubber, and a mixture of butyl rubber and ethylene-propylene rubber, which is added with 2 percent to 20 percent of modified polymer selected from a group including ethyl vinyl acetate, styrene-butadiene styrene copolymer, styrene-ethylene-butadiene-styrene copolymer, styrene-isoprene-styrene copolymer, low-density polyethylene, polypropylene, asphalt, fatty acid ester, and wax.

7. The vehicle component according to claim 1, wherein the second sealing member is made of a non-permeable material.

8.
