To provide a fall prevention device that can prevent breakage of a partition or a ceiling in an earthquake and secure a fall prevention function, even if the surface of the partition is constituted of low-strength members or the upper edge of the partition is connected to a grid ceiling inferior to strength, in the device for preventing the falling by connecting the partition with a cabinet.SOLUTION: A fall prevention device has a substrate 7 arranged on a floor surface F, and an absorber 27 fixed in a substrate 7 through an auxiliary frame 26. In an earthquake, a cabinet 1 swings while the substrate 7 deforms to wave, however the kinetic energy when returned from a forward tilted posture and turned is absorbed by the absorber 27, and therefore the cabinet 1 can be prevented from intensely colliding to the partition 6. As a result, the breakage deformation of the partition and the ceiling can be prevented and suppressed.SELECTED DRAWING: Figure 6 【課題】キャビネットと間仕切とを連結して転倒を防止する装置において、間仕切の表面が強度の強くない部材で構成されていたり、間仕切りの上端が強度に劣るグリッド天井に連結されていたりしても、地震に際して間仕切や天井の破損を防止して転倒防止機能を確保できる転倒防止装置を提供する。【解決手段】転倒防止装置は、床面Ｆに配置された基板７と、補助フレーム２６を介して基板７に固定されたアブソーバ２７とを有している。地震に際しては、基板７が波打つように変形しつつキャビネット１が揺動するが、前傾姿勢から戻り回動するに際しての運動エネルギがアブソーバ２７で吸収されるため、キャビネット１が間仕切６に激しく衝突することを防止できる。その結果、間仕切や天井部の破損変形を防止・抑制できる。【選択図】図６
