The present invention relates to a safety bookcase. The safety bookcase comprises: a bookcase main body for displaying a book and articles; and a support unit supporting the bookcase main body on the floor surface. The safety bookcase is to obtain safety by preventing a secondary accident by being prevented from being collapsed or from being fallen down even if the safety bookcase moves due to vibration energy applied from the outside. The support unit comprises: a wheel caster having a wheel main body connected to the bottom of the bookcase main body, and a wheel to idle in the wheel main body; and a support plate having a plate structure in which the bottom comes into contact with the floor surface, wherein a support rod extended from the wheel main body toward the lower side is fixed to the upper surface of the support plate. The support rod has a length in order for the lower part of the wheel to be arranged at a high position on the bottom of the support plate and is connected to the upper part of the support plate. The support rod and the support plate are connected in order for the support rod to be separated from the support plate when the vibration energy having a wavelength which is set in the outside is applied.
