  The fall prevention device 400 includes a band 420 (a connecting member) that connects the leg portion 10 a of the waterproof pan 10 on which the washing machine 20 is placed and the side surfaces 20 a on both sides of the washing machine 20.

  According to the overturn prevention devices 300 and 400, the structure around the waterproof pan 10 can be sufficiently held by being joined to the side surfaces 20a on both sides of the washing machine 20 while being easily installed with a very simple configuration. The washing machine 20 placed on the waterproof pan 10 can be prevented from falling without interfering with an object (a wall or a storage room).

  As mentioned above, although preferred embodiment in this invention was described, these are the illustrations for demonstrating this invention, and are not the meaning which limits the scope of the present invention only to these embodiment. Therefore, the present invention can be implemented in various modes different from the above-described embodiments without departing from the scope of the invention. That is, the present invention can be variously modified based on the configuration described in the claims, and these are also within the scope of the present invention.

  Further, in the first embodiment, for example, one (same) band 120 has been described as being inserted into each hole 115a of the two bolts 110, but the present invention is not limited to such a configuration. . As an example, a pair of bands 120 may be prepared, and one band 120 may be inserted and attached to each hole 115a of one bolt 110.

  In the first embodiment, for example, the band 120 is passed through the hole 115a of the bolt 110 to connect the bolt 110 and the washing machine 20, but the present invention is not limited to such a configuration. As an example, the head of the bolt 110 may be formed in an indented shape, and a band 120 may be wound around the base of the indented portion to connect the bolt 110 and the washing machine 20.

  In particular, the fall prevention device 100 is mounted on the waterproof pan 10 and the band 120 connected to the bolt 110 screwed to the floor 30 even if the bolt 110 is not fixed to the waterproof pan 10 but penetrated. Since the waterproof pan 10 can be held in a state where the waterproof pan 10 is sandwiched between the washing machine 20 and the tension is applied, the movement of the waterproof pan 10 can be restricted. Therefore, in the case where the waterproof pan 10 is not fixed to the floor 30 by screwing or the like, the anti-tip device 100 can be used for the washing machine 20 placed on the waterproof pan 10 even if it is shaken by an earthquake or the like.
