To propose an indoor unit of an air-conditioner capable of releasing the engagement of a projection of a bottom frame from a front surface and an engagement hole of an installation plate.SOLUTION: A bottom frame (20) has a projection (26) that is provided at a lower part and a rear part of the bottom frame (20), and projects downward to engage with an engagement hole (112) of an installation plate (100), an opening (21b) that is provided on a front surface and the lower part of the bottom frame (20), and an insertion space (S1) that extends from the opening (21b) toward a rear surface. By using The peripheral portion of the opening (21b) of the insertion space (S1) as a fulcrum (P1), using a rear side of the fulcrum (P1) of the insertion space (S1) as an action point (P2), a rod-shaped member (50) inserted from the opening (21b) is used to release the engagement of a projection (26) of the bottom frame (20) and the engagement hole (112) of the installation plate (100) by the principle of lever.SELECTED DRAWING: Figure 11 【課題】前面から底フレームの突起と据付板の係合穴との係り合いを解除できる空気調和機の室内ユニットを提案する。【解決手段】底フレーム(２０)は、底フレーム(２０)の下部かつ後部に設けられ、下方に向かって突出して据付板(１００)の係合穴(１１２)と係り合う突起(２６)と、底フレーム(２０)の前面かつ下部に設けられた開口(２１ｂ)と、開口(２１ｂ)から後面に向かって延びる挿入空間(Ｓ１)とを有する。挿入空間(Ｓ１)の開口(２１ｂ)の周辺部を支点(Ｐ１)とし、挿入空間(Ｓ１)の支点(Ｐ１)よりも後側を作用点(Ｐ２)として、開口(２１ｂ)から挿入される棒状部材(５０)を用いて、てこの原理により底フレーム(２０)の突起(２６)と据付板(１００)の係合穴(１１２)との係り合いを解除可能な構成をしている。【選択図】図１１
