And a hood surrounding a gong can be attached to a mounting object together with the gong, which sounds an alarm by striking it. The separable part 7d is provided on the bottom plate part 7a and is also detachably connected. When the alarm bell is installed without attaching the hood, the separable part 7d is detached from the mounting component 7 and can be used as a part for attaching the gong to the mounting object.SELECTED DRAWING: Figure 8
