ビス７のネジ部７ｂより小さ目とされている。 As shown in FIGS. 1 and 3, the nut member 9 has a rectangular head 10 interposed between the casing 2 and the tube plate 6 in the attached state.
and a square columnar leg 11 that protrudes from the head 10 and is fitted into the screw hole 8 in the installed state.
It is made of nylon 6 and is integrally molded. A screw hole 14 is formed in the leg portion 11 and opens into the head portion 10 . The end of the hole 14 on the side of the leg 11 is closed, and the inner peripheral surface thereof is provided with protrusions 15, 15, .
are integrally protruded. Moreover, this hole 14 is
It is smaller than the threaded portion 7b of the screw 7.

角柱状に限定されることなく、他の形状としても
よいことは勿論である。 The nut member 9 may be made of any suitable synthetic resin in addition to the nylon 6 used in this embodiment. In other words, a material with high heat insulation performance is selected for the nut member 9. Moreover, the reason why the screw hole 8 is made into a square hole and the leg part 11 of the nut member 9 is made into a square prism shape is that the screw hole 8 is made into a rectangular column shape.
This is to prevent the nut member 9 from rotating together when the nut member 9 is screwed, but it is limited to square holes and square prisms as long as it has a structure that can prevent the nut member 9 from rotating together. Of course, other shapes may be used instead.
次に図示の実施例における蒸発器３の取付順序
を説明する。 Next, the installation order of the evaporator 3 in the illustrated embodiment will be explained.

されて固定される。 First, screw holes 8 formed in the tube plate 6 of the evaporator 3
After fitting the leg portion 11 of the nut member 9 from the outside, the inner surface of the casing 2 is brought into contact with the head 10 of the nut member 9, and the screw 7 is screwed into the hole 14 of the nut member 9. Then, the leg portion 11 of the nut member 9 is expanded and fixed in the outer circumferential direction by the screwing force of the screw 7.

が防止されるのである。 In such an attached state, the head 10 of the nut member 9 is interposed between the casing 2 and the tube sheet 6, and the threaded portion 7 of the screw 7 is interposed between the tube sheet 6 and the screw 7.
The leg portion 11 of the nut member 9 is interposed between the tube plate 6 of the evaporator 3 and the casing 2.
Heat conduction to the threaded portion 7b of the screw 7 is effectively prevented by the nut member 9 made of synthetic resin with high heat insulation performance. Therefore, dew condensation on the casing 2 and the head 7a of the screw 7, which has been a problem in the past, is prevented.
なお、本考案は、図示の実施例に限定されるも

実用的な効果がある。(Effect of the invention) As described above, according to the invention, when fixing the tube plate 6 of the evaporator 3 to the casing 2 constituting the outer panel of the main body 1 using the screws 7, the tube plate 6 A head 10 interposed between the contact surfaces of the casing 2 and the tube sheet 6 and the head 1 are inserted into the screw holes 8 formed in the
Since the nut member 9 made of synthetic resin is fitted and consists of a leg part 11 that protrudes from the screw hole 8 and is inserted into the screw hole 8, and the screw 7 is screwed into the nut member 9, the casing 2, a nut member 9 made of synthetic resin is inserted between the tube sheet 6 and the threaded portion 7b of the screw 7.
The leg portion 11 of the nut member 9 is interposed between the casing 2 and the tube sheet 6, and the head portion 10 of the nut member 9 is interposed between the casing 2 and the tube sheet 6, thereby preventing heat conduction from the tube sheet 6 to the screws 7 and the casing 2. , is prevented by the synthetic resin nut member 9 having high heat insulation performance. Therefore, there is a practical effect that dew condensation on the casing 2 and the head 7a of the screw 7 can be prevented.
