It is easy to manage the above, and it is possible to prevent the intermediate connection portion 52 and the base plate 42 from coming into contact with each other to generate sound.
Further, since the discharge pipe 20 and the lead-out pipe 35 are arranged parallel to each other, the pipe support portion 50 and the lead-out pipe support portion 51 of the holding member 43 can also be parallel to each other, and the shape of the holding member 43 can be simplified. it can. Therefore, the holding member 43 can be easily formed.

Has been done. Specifically, the pipe support portion 151 has an arc-shaped receiving plate portion 151a facing the contact surface 45a of the base plate 42 with the elastic member 41 on the lead-out piping side interposed therebetween, and the base plate 42 side from both side ends of the arc-shaped receiving plate portion 151a. It is provided with a pair of side plate portions 151b and 151c extending to. The arc-shaped receiving plate portion 151a is provided in a section corresponding to substantially half the circumference of the discharge pipe side elastic member 40.

The pipe support portion 150 and the lead-out pipe support portion 151 are set in a shape that compresses and deforms the discharge pipe side elastic member 40 and the lead-out pipe side elastic member 41 in a state where the pipe fixture 133 is assembled.
Further, the holding member 143 includes a flange portion 55 continuous with the side plate portion 150b, an extending portion 51d extending from the side plate portion 151c, and an intermediate connecting portion 52 connecting the side plate portion 150b and the side plate portion 151b.
According to this modification, since the pipe support portion 150 and the lead-out pipe support portion 151 are formed in an arc shape along the shapes of the discharge pipe 20 and the lead-out pipe 35, respectively, the pipe support portion 150 and the lead-out pipe support portion are formed. The contact area between 151 and the discharge pipe side elastic member 40 and the outlet pipe side elastic member 41 can be increased, and the discharge pipe 20 and the outlet pipe 35 can be firmly fixed.

It should be noted that the above embodiment shows one aspect to which the present invention is applied, and the present invention is not limited to the above embodiment.
In the above-described embodiment and modification, the configuration in which the elastic member 41 on the outlet pipe side is fitted to the outer peripheral portion of the connection pipe portion 25a of the outlet pipe 35 has been described as an example, but the present invention is limited thereto. is not it. For example, the lead-out pipe side elastic member 41 may be fitted to the extension portion 31c of the branch pipe 31 of the lead-out pipe 35, and the branch pipe 31 and the discharge pipe 20 may be fixed with a pipe fixture.
Further, in the above-described embodiments and modifications, the switch main body 25b of the high-voltage switch 25 has been described as an example of the pressure detection unit, but the present invention is not limited thereto. The pressure detection unit may be provided with a sensor for detecting the pressure of the refrigerant in the discharge pipe 20 and a switch main body 25b, or may be provided with only a sensor for detecting the pressure of the refrigerant in the discharge pipe 20.
