An intermediate mounting portion that engages with the front surface of the main body, and the main body has a main body side engaging portion provided at an intermediate portion in the longitudinal direction, and the intermediate mounting portion is connected to the main body side engaging portion. It has an intermediate engagement part which controls the movement of the said intermediate attachment part to the direction which engages and leaves | separates from the front surface of the said main body.

According to this configuration, the front panel is attached to the main body of the indoor unit via the intermediate attachment portion. Therefore, it is not necessary to provide an engaging portion or the like for attaching the front panel to the main body on the front panel, and the degree of freedom in design increases.
Further, since the intermediate mounting portion is engaged with the front panel, for example, the fixing force is improved as compared with the case where the intermediate mounting portion is fixed to the front panel using only adhesive means such as double-sided tape. Moreover, there is no possibility that the front panel falls due to a decrease in adhesive force.
Furthermore, since the main body and the intermediate mounting portion are engaged with each other at the intermediate portion in the longitudinal direction of the main body, compared with the case where the front panel is engaged with the main body only at both ends, the front panel in the intermediate portion in the longitudinal direction is engaged. Floating is prevented.

  An indoor unit of an air conditioner according to a second aspect of the present invention includes a display unit provided at an intermediate portion in the longitudinal direction on the front surface of the main body, and the main body side engagement portion is more display than both ends in the longitudinal direction.

A pair of intermediate engaging portions 33b for restricting the movement of the first mounting plate 31 to each other.

According to this configuration, the front panel 20 is attached to the main unit 10 of the indoor unit 1 via the first attachment plate 31 and the second attachment plates 32L and 32R. Therefore, it is not necessary to provide the front panel 20 with an engaging portion or the like for attaching the front panel 20 to the main body unit 10, and the degree of freedom in design increases.
Further, since the inside of the first mounting plate 31 and the second mounting plates 32L and 32R is engaged with the front panel 20, for example, the first mounting plate 31 and the second mounting plate using only adhesive means such as double-sided tape. The fixing force is improved as compared with the case where 32L and 32R are fixed to the front panel 20. Further, there is no possibility that the front panel 20 will drop due to a decrease in adhesive force.
Furthermore, since the main body unit 10 and the first mounting plate 31 are engaged with each other at the middle portion of the main body unit 10 in the longitudinal direction, the front panel 20 is engaged with the main body only at both ends. The front panel 20 is prevented from floating in the middle part.

  Further, the indoor unit 1 according to the present embodiment includes a light emitting display unit 42 provided in the middle portion in the longitudinal direction on the front surface of the main unit 10, and the engagement holes 10 e and 10 f are both ends in the longitudinal direction of the main unit 10.
