Abstract:

PROBLEM TO BE SOLVED: To provide a fall prevention device of a waterproof plate having both durability and readiness.SOLUTION: A locking body 29 is rotatably installed so that upper-lower end parts approach and separate to a waterproof plate opposed surface in a guide groove of a guide rail 2. Upper-lower receiving parts 30a and 30b vertical provided at an interval, are provided in a place of the guide rail 2 positioned on the lower side than the locking body 29. The locking body 29 comprises an abutting part 29c capable of abutting on at least the upper receiving part 30a by descent of the waterproof plate. When the waterproof plate descends by normal operation, the abutting part 29c abuts on the upper receiving part 30a, and returns to an original attitude by dead weight of the locking body 29 after rotating the locking body 29. When the waterproof plate falls, before returning to the waterproof plate side of its lower part by the dead weight of the locking body 29, the lower end of the locking body 29 is locked on the lower receiving part 30b, and a fall of the waterproof plate is prevented. A swing prevention member such as a magnet 35 is provided for preventing swinging of the locking body 29.
