On the other hand, in FIG. 11, since the position of the front panel 3 is also largely shifted also in the first locking means K1, the first locking member 41 can be locked without reaching the first coupling member 43. FIG. There is no.

In this manner, when the convex portion 3A does not catch the recess 21 of the locking portion 17D, the convex portion 3A slides off the inclined surface 22 and the convex portion 3A is at least the lower end portion ( Since it moves to the position of 22a, the position of the main body case 1 and the front panel 3 is largely shifted | deviated, and the 1st and 2nd locking means K1 and K2 cannot be locked. Since the front panel 3 and the ceiling panel 5 are rattled by this, the operator recognizes that the panels 3 and 5 are not caught. Since the worker performs the panel attaching work again, the panels 3 and 5 can be securely fixed, so that the risk of falling of the panel due to adhesion failure can be reduced.

In the main body case 1, the front panel 3, and the ceiling panel 5 configured as described above, the front panel 3 and the ceiling panel 5 are integrally connected at an angle of approximately 90 degrees. The ceiling panel 5 is held on the basis of the panel position display portion 41a and the main body position display portion 14a by holding the lower portion of the connected panel (lower portion of the front panel) with both hands as shown in FIG. The ceiling surface portion 17C of the main body case 1 is transported to the burning position. Then, the front panel 3 is press-fitted into the main body case 1 side. Then, the pair of protrusions 3A formed on the front panel 3 are caught by the locking portions 17D of the main body case 1. Thereafter, the first locking member 41 is held by the first engaging portion 43 by pressing the front panel 3 toward the main body case 1 side. And the fixing hole 47 is fitted to the boss 45a by slidingly operating the handle 49 of both left and right lower edge parts. As a result, the front panel 3 and the ceiling panel 5 are stacked on the main body case 1 and fixed.

As mentioned above, although this invention was demonstrated based on one Example, this invention is not limited to this, It can change suitably within the range which does not deviate from the summary.

In the present embodiment, two types of the first locking means K1 and the second locking means K2 are provided in the central portion and the lower portion of the air conditioner. However, these locking means are not limited to two types, but one or three types. It may be more than a kind. In addition, the mechanism is not limited to this embodiment.
