The main body 2 is engaged with the band-shaped surface fastener 3 and the main body side surface fastener 4 provided on the hook 5 on the lower surface of the base portion 1, and the main body 2 is held in a form suspended by the fastener. I have. FIG. 3 shows a central cross section in this state. The convex portion 8 of the main body 2 is coupled to the concave portion 7 provided in the base portion 1, and in this state, the main body 2 is combined with the base 1,
The concave portion 9 provided in the main body 2 is fixed by a lock mechanism 6 provided as a coupling mechanism provided in the base portion 1. When the main body 2 is fixed to the base portion 1, the belt-shaped hook-and-loop fastener 3 is folded into a slight space between the main body and the base 2 while being engaged with the hook-and-loop fastener 4 on the main body side. It fits in shape. When the lock mechanism 6 is operated, the concave portion 9 of the main body 2 is disengaged from the lock fitting, and attempts to rotate around a portion where the concave portion 7 of the base portion 1 and the convex portion 8 of the main body 2 are in contact. Then, the belt-shaped hook-and-loop fastener 3 is deformed so that its loop shape is elongated, and stops when it is completely extended. FIG. 3 shows the state at this time. Furthermore, when the sensor body is pulled downward from this state, the hook-and-loop fastener comes off,
The main body 2 is completely separated from the base 1.

り、組み立て作業上の制約が少なくて済む。As described above, according to the falling-off prevention mechanism of the alarm device of the present invention, the operation of releasing the coupling mechanism and the subsequent operation of separating the main body and the base portion are performed separately. Even if it is operated with one hand, the main body is no longer dropped. The hook-and-loop fastener used in the present invention suffices to use what is called Magic Tape (trademark), which is frequently used as a detachable hook-and-loop fastener, so that it can be used at any number of places as needed. For this reason, an alarm device having a configuration in which the base portion is separated from the entire main body when the coupling mechanism is released can be adopted, and the application range is wide. Since the hook-and-loop fastener using a fabric as a base material is used, when the main body is fixed to the base portion, the shape becomes small, and the storage space is small.
In addition, since the belt-shaped hook-and-loop fastener is formed in a loop shape so that the engagement surface comes to the outside, the engagement surface is always located below simply by hooking on the hook of the base portion. Less restrictions.

の脱落防止機構。1. A base which is directly fixed to a ceiling or the like, and a main body which is fixed to the base. Detachment of the main body from the base is accompanied by a release operation of a coupling mechanism for fixing the main body to each other. In the alarm device configured to be performed by the weight acting on the self-weight and the force acting in the separating direction of the coupling mechanism, the lower surface of the base portion is formed in a loop shape with a hook provided on the base portion and an engaging surface on the outside. A formed belt-shaped hook-and-loop fastener is provided, and a hook-and-loop fastener engaging with the strip-shaped hook-and-loop fastener is fixed at a position on the upper surface of the main body corresponding to the strip-shaped hook-and-loop fastener. mechanism.
