In order to reduce the labor, a so-called temporary fixing device is provided. That is, as shown in FIG.
A pair of hooks 17 and 19 are fixed to the lower part of the panel, and a pair of hooks 21 and 23 are provided on the side of the decorative panel 11 to be engaged with the hooks 17 and 19, respectively.
As shown in FIG. 2, reference numerals 1 and 23 are fixed to the wall 13 a of the inlet 13 of the decorative panel 11.

The engaging member 17 and the hook 21 that engage with each other are as shown in FIG. 3. The opening having a width larger than the width W _{1 of the} hook 21 is provided in the engaging member 17. an upper engagement hole 17a that includes a lower engaging hole 17b which is opened with a width W ₁ and substantially the same width dimension of the connection hook member 21 is formed on the upper engaging hole 17a. Upper engagement hole 17a
Is wider at the top, so that when the hook 21 is hooked, it can be easily hooked even if the decorative panel 11 is slightly shifted in the lateral direction.

[0013] A locking device 19 and a hooking device 2 which engage with each other.
4 is formed as shown in FIG. 4 and is formed to be wider than the above-described locking tool 17 and hooking tool 21 (that is, width W ₂ > width W ₁ ). An upper engagement hole 19a having an opening having a width greater than the width W ₂ of the hooking member 21 in the locking part 19, the width W ₂ and substantially the same connection hooking member 23 in this upper engaging hole 19a An open lower engaging hole 19b having a width dimension is formed, and the upper engaging hole 19a is wider at the upper side. When the hook 23 is hooked, the decorative panel 11 is slightly shifted in the lateral direction. Even it can be easily hooked.

The locking members 17 and 19 are connected to one of the locking members 17.
Is a fixed type, and the other locking member 19 is a swing type. As shown in FIG. 5, the swing type locking member 19 is provided with two pins 2 on a bracket 25 of the unit body 1.
