Means are provided, and along the auxiliary guide means, both lower surfaces and both side ends of the filter 4 indicated by a two-dot chain line in FIG. 5 are smoothly guided and moved.

  At that time, the upper surfaces of both sides of the filter 4 can be smoothly guided and moved along the back surface 15b of the suction grille 15a facing the bottom surface 10a of the auxiliary guide means, as shown in FIG. Yes.

  Thus, both side portions of the filter 4 at the lower portion of the suction grille 15a corresponding to the suction port 2 on the upper surface portion of the front frame 1g are held so as to be smoothly slidable by the auxiliary guide means and the back surface 15b. In particular, since the suction grille 15 also serves as means for guiding the upper surfaces of both sides of the filter 4, the auxiliary guide means having an L-shaped cross section composed of the bottom surface 10a and the side surface 10b. As a guide means 10 having a U-shaped cross section.

  For example, when the auxiliary guide means is formed in a U-shaped cross section, the suction grill 15a is overlapped on the upper surface of the U-shaped cross section, but is formed in an L-shaped cross section. Thus, as an indoor unit of an air conditioner, the structure can be reduced by about 3 millimeters corresponding to the thickness of the upper surface portion, the height dimension can be reduced, and the weight can be reduced. It becomes the structure which can reduce the usage-amount of the raw material (synthetic resin) equivalent to the thickness of an upper surface part.

  The suction grill 15a has sufficient strength as a suction grill even if the auxiliary guide means is formed in a U-shaped cross section and does not overlap the upper surface of the U-shaped cross section. Therefore, there is no risk of insufficient strength.

  As described above, according to this configuration, the cleaning device 5 is attached along the suction port 2 provided in the front surface portion and the upper surface portion of the front frame 1g configuring the frame portion 1. The filter 4 can be smoothly moved back and forth without being inclined, and can be cleaned.
