    摘要： Provided is a vibration damping device which can efficiently absorb vibration energies ranging from vibration energy of small magnitude to vibration energy of large magnitude regardless of a length of a period of vibrations of a structure with the simple structure thus acquiring both high practicability and general-use property. A vibration damping device 1 for suppressing vibrations of a structure includes: a slide body mechanism 2 having a concave slide body 3 and a convex slide body 4 which are fixed to the structure and are arranged so as to be slidable relative to each other in a reciprocating manner in a state where the slide bodies face each other in an opposed manner; and a biasing means (leaf springs 5) which biases the slide body mechanism 2 in the direction that the slide bodies 3, 4 which are arranged so as to be slidable relative to each other in a reciprocating manner are pushed to each other, wherein each slide body 3, 4 has: a first slide surface having a shape which increases a height of the slide body mechanism 2 along with the increase of a displacement amount of the slide body in one sliding direction from a neutral position within a range of reciprocating sliding relative to the sliding counterpart slide body; and a second slide surface having a shape by which the height of the slide body mechanism 2 is increased along with the increase of the displacement of the slide body in the other sliding direction from the neutral position.
