Abstract: PROBLEM TO BE SOLVED: To solve a problem that a ceiling pan is undesirably detached from the rear face of a ceiling material when the conventional auxiliary device for fitting having the ceiling pan for rigidly fitting a ceiling-embedded type speaker system to a ceiling is applied to the ceiling where a structure protrudes upward from the rear face of a ceiling material and that the ceiling-embedded speaker system cannot rigidly be fitted even if the ceiling material and the ceiling pan are clamped by a clamping piece of the ceiling-embedded speaker system.
SOLUTION: The auxiliary device for fitting ceiling-embedded speaker system 10 is provided with a ceiling reinforcing member 11 and a long member 21. The ceiling reinforcing member 11 has a planar part 12 and an erect part 14 formed to erect from the planar part 12. The erect part 14 can take: a sliding state where it can slide in a vertical direction with respect to the long member 21 and can be displaced; and a fixed state where the erect part 14 can be fixed so that it cannot be displaced in the vertical direction with respect to the long member 21.
