An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. First, in Figure 1, 11
1 is a ventilation fan main body which is a device main body, and this is made up of a casing 12 having an opening 12a on the lower surface and a partition plate 13, a blower device 14, etc. arranged therein, and this ventilation fan main body 11 is attached to a room wall, for example, a ceiling board 15. ing. 16, 16 are holders attached to the lower surface of the partition plate 13, and the lower surface plate portions 16a, 16a have long holes 17 (one holder 16) as shown in FIG.
(only those shown) are formed. 18,18
3 is a wire spring, which has a bifurcated shape that can be expanded and contracted, and has an annular engagement portion 19 formed at its base end as shown in FIG. And this wire spring 1
8 is slidably provided in the elongated hole 17 of the holder 16, that is, by this sliding, it can be pulled out from the position shown by the broken line in FIG. Yes, and in this case, it will remain in that state at that drawer position and arrow A
When pushed in the direction, it moves inward due to its own spring force in the direction of expansion. In FIG. 1, reference numeral 20 denotes a decorative board, and a frame 21 is attached to the peripheral edge of the surface thereof, and a ventilation gap S is provided on the back surface, and a decorative frame 22 is attached to the connector 2.
3 and 23. Mounting portions 24, 24 are formed on the connectors 23, 23, and the mounting portion 24 has an engaged portion 25 and a pressing portion 26 that project laterally, as shown in FIG. Become. The engaged portion 25 has a hook-shaped claw portion 25a projecting downward at its tip, and the pressing portion 26 also has a claw portion 26a projecting upward at its tip. It forms a hook shape. Here, a protrusion 27 is formed at the distal end of the engaged portion 25 and protrudes in the direction opposite to the claw portion 25a, that is, in the direction of entry of the wire spring 18 (direction of arrow A). The dimension L from the upper side to the protruding end of the protrusion 27 is set to be larger than the diameter dimension (center diameter dimension) D of the engaging portion 19 of the wire spring 18. In this case, the protrusion 27 extends from the lower end of the claw portion 25a in the engaged portion 25.
The dimension 1 to the protruding end is determined to be smaller than the inner diameter dimension d of the engaging portion 19. In addition, this mounting part 24
An auxiliary protrusion 24a is formed at the tip.

Now, in the above configuration, when attaching the decorative panel 20 to the ventilation fan main body 11 from the removed state shown in FIG.
First, as shown by the solid line in FIG. 3, the wire spring 18 is fully pulled out and held in the pulled-out position, and the engaged portion 25 of the mounting portion 24 is inserted into the engaging portion 19 of the wire spring 18. Push up the decorative board 20 in the direction of arrow A. Then, the lower end of the engaging portion 19
6 in the direction of arrow A, and the wire spring 18
moves in the direction of arrow A based on its own spring force, and the engaging portion 19 engages with the engaged portion 25 (see the two-dot chain line in FIG. 3), thereby forming the decorative board 20 as shown in FIG. It is attached to the ventilation fan main body 11 so as to cover the opening 12a.

By the way, during this installation, especially when pushing up the decorative board 20 in the direction of arrow A, the decorative board 20 may be tilted and the mounting portion 24 may be tilted (see FIG. 5); however, according to this embodiment, A protrusion 27 is provided on the engaged portion 25.
Since the dimension L from the pressing part 26 to the protruding end of the protruding part 27 is set to be larger than the diameter D of the engaging part 19, the upper end of the engaging part 19 This is where the protrusion 27 engages, and it is possible to prevent the relative inclination between the attachment part 24 and the engagement part 19 from increasing, and therefore the engagement part 19 is moved in by the spring force of the wire spring 18. Also, the engaging portion 19 is connected to the engaged portion 25.
As a result, problems such as the decorative board 20 falling off can be reliably prevented.

In particular, according to this embodiment, the dimension l from the lower end of the claw portion 25a to the protruding end of the protrusion 27 in the engaged portion 25
Since it is set to be smaller than the inner diameter dimension d of the engaging portion 19, it is easy to remove the decorative plate 20 from the wire spring 18.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the holder for holding the wire spring 18 is not limited to the holder 16 having the elongated hole 17, and other embodiments of the present invention may be used. As shown in FIG. 6, the holder 29 may have a pair of fitting recesses 28, 28, and the present invention may be applied not only to ventilation fans but also to general air conditioners having similar circumstances, without departing from the scope of the invention. It can be implemented with various modifications.
