Abstract

To provide a sensor mounting apparatus which prevents a fire sensor from being easily detached from a sensor mounting part.SOLUTION: A sensor mounting apparatus 1 comprises a sensor mounting part 4, on which a fire sensor is mounted. The sensor mounting part 4 is provided with: a pressing metal fitting 7 which crimps an insertion metal fitting at the side of the fire sensor; a receiving metal fitting 8; and a stopper 9. The pressing metal fitting 7 includes a folding spring part 7c in which a pressing part pressing the insertion metal fitting onto the receiving metal fitting 8 side is provided in a distal end side portion closer to a distal end than a folding part. The stopper 9 prevents a proximal end side portion closer to a proximal end than the folding part of the folding spring part 7c from rotationally moving when the pressing part presses the insertion metal fitting onto the receiving metal fitting 8 side.SELECTED DRAWING: Figure 2
