PROBLEM TO BE SOLVED: To provide an operation unit ensuring reliable slide operation of a lid, by ensuring click feeling at the opening and closing position of the lid, while improving designability by covering a hidden button with the lid, and to provide an air cleaner including the same.SOLUTION: An operation unit has a lid 16 covering a hidden button 18, and a support mechanism for supporting the lid 16 slidably. The support mechanism includes a rail 20 extending in the slide direction of the lid 16, a groove fitting to the rail 20 and sliding the lid 16 in the slide direction, a pair of protrusions biased to the rail 20 by an elastic member and clamping the rail 20, and recesses 20a formed at predetermined positions of the rail 20, and into which the protrusions are fitted.SELECTED DRAWING: Figure 3-1【課題】隠しボタンを蓋で覆ってデザイン性を向上させつつ、蓋の開閉位置でクリック感が得られるようにして、蓋のスライド操作が確実に行える操作部およびそれを備えた空気清浄機を得ること。【解決手段】隠しボタン１８を覆う蓋１６と、蓋１６をスライド可能に支持する支持機構とを有し、支持機構は、蓋１６のスライド方向に延在させたレール２０と、レール２０と嵌合して蓋１６をスライド方向に摺動させる溝部と、弾性部材によりレール２０に付勢されてレール２０を挟む一対の突起部と、レール２０の所定箇所に形成され、突起部が嵌まる凹部２０ａと、を備えている。【選択図】図３－１
