- Patent Document 1 describes a structure in which the guide groove of the slide door is slidably slid, as described above, by changing the lateral width of the slide door to the width of the guide groove. Because of the adoption of a method that makes the air flow smaller, the air flowing through the air flow path collides and vibrates, causing rattling and noise, and also causing air to leak from gaps. .
- the air-conditioning case is easily deformed because the air-conditioning case has a complicated shape with thin resin and has a large air flow path inside.
- the main cause of the deformation is an external force.
- the deformation of the mounting foot portion at the time of mounting to the vehicle body is different in the vertical direction, so that the stress affects the case. In this case, twist deformation is likely.
- width heat is emitted from the heater core.
- the need to reduce the gap between the slide door and the heater core for the purpose of downsizing the air conditioner for a vehicle is strong.
- the slide door is heated by the heat radiation from the heater core, and is easily deformed by twisting.
- the deformation of the air-conditioning case is something that should not occur.
- the linear guide groove in which the slide door moves may be affected, and may be deformed into a curved shape.
- the linear slide door comes into contact with the guide groove in which the slide door moves, and the resistance increases. This movement of the sliding door is an important factor for temperature control, and if this movement is not possible, a serious problem will occur in that air conditioning control cannot be performed.
- the alignment shown in the aforementioned Japanese Patent Application No. 2002-379903 is based on the male engagement portion 26 and the female engagement portion.
- the male engaging portion 26 is a protruding piece having a predetermined width
- the female engaging portion 28 is also provided with the male engaging portion. It is a concave groove having a predetermined width equivalent to a predetermined width of the projecting piece of the joint portion. Therefore, the pair of male engagement portions 26 can be reversely assembled to the pair of female engagement portions 28, and the engagement shape of the shaft outside the air-conditioning case differs due to erroneous assembly. There were also inconveniences that could not be combined with external devices.
- a sliding door is provided with seal members protruding in the sliding direction at both ends thereof.
- the ratio of the horizontal dimension to the vertical dimension should be. If the seal material is installed in the vertical direction (moving direction), there is an advantage that the allowable width (dimension) of the sheet allowance (compression allowance) increases.
- increasing the longitudinal dimension of the sealing material indefinitely may cause the sealing material to buckle or fall over, causing inconvenience of poor sealing.
- the vehicle slide door described in Patent Document 5 is formed by combining a force rack and gears that are significant when the guide surface of the rail is horizontal, and has a plurality of teeth that mesh with each other.
- the configuration is not always appropriate as a means for eliminating dust and dust.
- it is not intended to eliminate dust and dust on the pinion side of the shaft, and dust and sand are also clogged in the recesses with narrow teeth openings on the rack, and solidified by moisture etc.

- Patent Document 1 when sealing between the door body and the contact portion, it is necessary to move the door body in a direction intersecting with the sliding direction. When the door itself moves from the end position, it is necessary to move the door body against the flow of air. For this reason, there is an inconvenience that it is difficult to secure a linear movement and a smooth movement of the door body.
- a seal member is attached to the door body, and the seal member is moved to the stop position of the slide door.

- a space 86 is formed inside to seal the fluid, and the abutting portion 85 can be extended to the side by pressing the abutting portion 85.
- the bellows portion 84 may be brought into close contact with the inner wall of the wall portion 80.
- the above configuration has a configuration in which the sealing member 70 is swelled and deformed in a direction perpendicular to the sliding direction to bring the sealing member 70 into close contact with the inner wall of the wall portion 80.
- the sealing member 70 slides against the wall portion 80 by forming the opposing wall surfaces of the wall portions 80 provided on both sides so that they gradually approach each other as the seal member enters.
- the pressure contact may be performed in a direction different from the direction.
- the seal member 70 is pressed against the other wall portion 80 by forming a curved surface 87 that gradually brings the wall surface of one side wall portion 80 closer to the other wall portion, and the slide door 2 stops at the stop position of the slide door 23.
- a good seal is provided between 3 and the air conditioning case 3.
- the pressing deformation portion 70a is configured by the entirety of the sealing member 70.
- the pressing deformation portion 70a may be partially formed at, for example, an end of the sealing member 70. You may.
