## Abstract

An air conditioning apparatus for a vehicle that includes a frame having an opening through which an airflow passes, and a sliding door which adjusts an aperture ratio of the opening by being slid along a wall surface formed with the opening of the frame in an upstream side of the opening, wherein the sliding door includes: a shield plate to shield the airflow; and a seal member which extends from the shield plate in a sliding direction of the sliding door and is more easily bent than the shield plate, and which is bent by receiving the airflow, thereby coming into contact with the wall surface of the frame.

## Claims

### Claim 1

An air conditioning apparatus for a vehicle that includes a frame having an opening through which an airflow passes, and a sliding door which adjusts an aperture ratio of the opening by being slid along a wall surface formed with the opening of the frame in an upstream side of the opening,
wherein the sliding door includes:
a shield plate to shield the airflow; and
a seal member which extends from the shield plate in a sliding direction of the sliding door and is more easily bent than the shield plate, and which is bent by receiving the airflow, thereby coming into contact with the wall surface of the frame.

### Claim 2 (depends on 1)

The air conditioning apparatus for a vehicle according to claim 1, wherein the seal member has restoration properties.

### Claim 3 (depends on 1)

The air conditioning apparatus for a vehicle according to claim 1, wherein the frame includes:
a seal surface which is disposed adjacent to the opening and comes into contact with the seal member; and
a guide which guides the sliding door and approaches the seal surface as moving away from the opening.

### Claim 4 (depends on 1)

The air conditioning apparatus for a vehicle according to claim 1, wherein the seal member is inclined in a downstream side of the airflow.

### Claim 5 (depends on 3)

The air conditioning apparatus for a vehicle according to claim 3, wherein the guide is curved so that a central portion of the sliding door in the sliding direction thereof swells toward the downstream side of the airflow.

### Claim 6 (depends on 1)

The air conditioning apparatus for a vehicle according to claim 1,
wherein the seal member includes:
a fore-end portion which has a contact surface with the frame, the contact surface being a curved surface;
a base portion connected with the shield plate; and
a neck portion which is connected with the fore-end portion and the base portion and is thinner than the base portion.

### Claim 7 (depends on 6)

The air conditioning apparatus for a vehicle according to claim 6, wherein a position of the seal member is set so that an angle between an axis, which penetrates centers of the base portion, the neck portion, and the fore-end portion, and the wall surface of the frame, which comes into contact with the seal member, in the upstream side of the airflow is larger than 90° and less than 180°.
