[Effect of Embodiment 1]
The first contact portion 3A of the first mechanism 3 is located at the first position where the heat exchanger 4 is in contact with the heat exchanger 4 so as to be lifted from the installation position, and the heat exchanger 4 is located at the installation position. As such, it is movable to a second position away from the heat exchanger 4. By setting the position of the first contact portion 3A as the first position, the operator can separate the seal members 2A to 2F from the support members 1A to 1D. Therefore, it is possible to prevent the seal members 2A to 2F from rubbing against the support members 1A to 1D when the operator inserts and removes the heat exchanger 4, and the work load when the operator inserts and removes the heat exchanger 4 Can be suppressed.

In the first embodiment, it is assumed that the first contact portion 3A is rotatably provided, but the present invention is not limited to this. The first contact portion 3A does not have to be rotatable. Even if the first contact portion 3A does not rotate, the effect of suppressing the work load when the operator inserts and removes the heat exchanger 4 can be obtained. If the first contact portion 3A is rotatable, the effect of suppressing the work load when the operator inserts and removes the heat exchanger 4 increases. When the first contact portion 3A is not rotatable, the first contact portion 3A may be composed of a member having a small frictional resistance when rubbing against the facing portion Fr2 of the frame 4B1 of the heat exchanger 4. For example, it is preferable to form irregularities on the surface of the first contact portion 3A or the lower surface of the facing portion Fr2.
