PROBLEM TO BE SOLVED: To provide a smoke fire detector protective cover having high versatility, facilitating attachment/detachment to/from a mounting object, and having a simple structure.SOLUTION: A smoke fire detector protective cover includes a cover body 2 covering a smoke fire detector 13A while storing the smoke fire detector 13A in its hollow part, and an elastic cushioning material 4 fixed onto the inside side surface of the cover body 2. The elastic cushioning material 4 is a sponge body, and includes a hollow part 4a or slit capable of inserting/drawing the smoke fire detector 13A in/out its center, or a combination of the hollow part and slit. When the smoke fire detector 13A is inserted into the elastic cushioning material 4, the elastic cushioning material 4 elastically deforms along the shape of a peripheral side surface positioned at the outermost portion of the smoke fire detector 13A, and the cover body 2 is held on the peripheral side surface of the smoke fire detector 13A.SELECTED DRAWING: Figure 3 |
