<p>A speaker unit mounting structure includes a provisionally fastening mechanism (10) for fastening a speaker unit (1) to a ceiling (60) with a cabinet section (2) of the speaker unit inserted in a mounting hole (61) of the ceiling. The provisionally fastening mechanism includes a provisionally fastening tab (11) formed of resilient metal, fixed to the outer peripheral side surface of the cabinet section and having a stepped engaging section (13) engageable with the inner peripheral edge portion of the mounting hole. Engagement of the engaging section with the inner peripheral edge portion of the mounting hole can be canceled by a human operator pressing, from the face side of the ceiling, an operating section (15) of the tab, exposed to a gap (X) between the front side and a flange portion (5) of the speaker unit, to thereby resiliently deform the operating section.</p> |
