a sealing material surrounding an expansion valve; and

a case which is constituted by a plurality of divided parts and surrounds and pinches the sealing material by a first division part and a second division part that are two fittable divided parts,

wherein the first division part and the second division part include sealing material support portions that penetrate the sealing material and support the sealing material, and

wherein the sealing material includes a step portion in a region that comes into contact with the sealing material support portions.

2. The vehicle air conditioner according to claim 1 ,

wherein the sealing material includes a slit that sets a penetration direction of the sealing material support portions as a depth direction in the region that comes into contact with the sealing material support portions.

3. The vehicle air conditioner according to claim 1 ,

wherein the sealing material support portions are provided so as to be extended in an insertion direction when the sealing material is attached to the divided parts, and a surface of the sealing material into which the sealing material support portions penetrate and the sealing material support portions are tilted to the penetration direction side of the sealing material support portions, as the surface and the sealing material support portions advance in the insertion direction.

4. The vehicle air conditioner according to claim 1 ,

wherein the second division part includes an opening through which the expansion valve is exposed, and an opening side sealing material support portion that is formed around the opening and penetrates into the sealing material.

5. The vehicle air conditioner according to claim 1 , further comprising:

a position regulation means which is provided in at least one of the first division part and the second division part and regulates the position of the sealing material.

6. The vehicle air conditioner according to claim 1 ,

wherein a groove portion that guides the other sealing material support portion is provided in any one of the first division part and the second division part, and an inlet region of the groove portion is formed so as to be spread out.

7. The vehicle air conditioner according to claim 1 ,

wherein the sealing material support portion of the first division part is in line-contact with the sealing material support portion of the second division part.

8. A vehicle air conditioner comprising:

a sealing material surrounding an expansion valve; and

a case that is constituted by a plurality of divided parts and surrounds and pinches the sealing material by a first division part and a second division part which are two fittable divided parts,

wherein the first division part and the second division part include sealing material support portions that penetrate into the sealing material and support the sealing material, and

wherein the sealing material includes a slit that sets a penetration direction of the sealing material support portions as a depth direction in a region where the sealing material support portion of the first division part comes into contact with the scaling material support portion of the second division part.
