## Abstract

A gasket is provided which is configured so that a gasket body is easily separated from a carrier film and the positional shift of the gasket body in stacking can be prevented. The gasket has a combination of a gasket body which contains only a rubber-like elastic body and which, in order to seal a gap between one member and the other member, is mounted in the other member and a carrier film separably stuck to one surface side in the thickness direction of the gasket body, in which an engagement portion is formed in the other surface in the thickness direction of the gasket body at a position corresponding to a portion to be engaged formed in the other member, and the gasket body is mounted in the other member by engagement of the engagement portion and the portion to be engaged.

## Claims

### Claim 1

A gasket comprising:
an elastic gasket body; and
a removable carrier film attached to one surface in a thickness direction of the elastic gasket body,
wherein the elastic gasket body includes a pair of recesses formed in another surface of the elastic gasket body that is opposite to the one surface in the thickness direction of the elastic gasket body, the pair of recesses being located at positions that correspond to a pair of projections that are formed on a member to be sealed with the gasket,
the pair of recesses are configured to receive the pair of projections, and
the pair of recesses each have a depth that is less than a thickness of the elastic gasket body.

### Claim 2 (depends on 1)

The gasket according to claim 1, wherein
the pair of recesses extend along an entire periphery of the elastic gasket body.

### Claim 3 (depends on 1)

The gasket according to claim 1, wherein
the pair of recesses are spaced apart and parallel to one another.

### Claim 4 (depends on 1)

A method for mounting the gasket according to claim 1, comprising:
mounting the elastic gasket body on the member to be sealed by engaging the pair of recesses with the pair of protections that are formed on the member to be sealed, and then separating the carrier film from the elastic gasket body.

### Claim 5 (depends on 2)

A method for mounting the gasket according to claim 2, comprising:
mounting the elastic gasket body on the member to be sealed by engaging the pair of recesses with the pair of projections that are formed on the member to be sealed, and then separating the carrier film from the elastic gasket body.

### Claim 6 (depends on 3)

A method for mounting the gasket according to claim 3, comprising:
mounting the elastic gasket body on the member to be sealed by engaging the pair of recesses with the pair of projections that are formed on the member to be sealed, and then separating the carrier film from the elastic gasket body.
