がスムーズに行える等、種との効果を奏する。As described above, in the front grille mounting apparatus for an air conditioner according to the present invention, conventionally, the mating portion between the front grille and the underframe may come into surface contact due to dimensional variations or the way of fitting. During the operation of the air conditioner, the above-mentioned surface contact caused abnormal sound. However, as in the present invention, the line contact is made by the protrusions provided at the peripheral portion of the front grille and at the corners of the underframe main body. Thereby, the contact area can be minimized, and the abnormal noise during operation of the air conditioner, which has been a problem, can be suppressed. In addition, when the front grille is fitted to the underframe, the projections also serve the role of squeezing, and the front grille can be set smoothly, which is advantageous in some respects.
