策はなかった。2. Description of the Related Art In recent years, floor impact noise from the upper floor has become a serious problem in apartment houses and the like. There are two types of floor impact sounds: a floor impact sound caused by a light impact that occurs when walking normally, and a floor impact sound caused by a heavy impact caused when a heavy object is dropped or a child jumps. There was no effective solution other than thickening the floor slab.

As shown in FIGS. 1 and 2, when an impact load is applied to the joist 2 in a state where the buffer mechanism A is interposed between the puller 1 and the joist 2, first, the first leaf spring 4a is elastically deformed. Then, both ends slide on the base plate 3, and the impact vibration noise is absorbed.

4 has a cross-sectional shape in which the right side surface in FIG. 4 is gentle and the left side surface is steep. On the contrary, when the elasticity is restored, a large resistance force is given by the contact with the projection 8. For this reason, the vibration of the elastic member 4 is attenuated in a short time, and the livability is improved.
