PURPOSE: A floating structure of floor for a railway vehicle for preventing that the cracking generates in the floor material is provided to increase the durability of the reinforcing frame part by combining the lower side central part of bimetal and the reinforcement frame. CONSTITUTION: A floating structure of floor for a railway vehicle includes a board(300), a support frame(100), a first connection plate(200), a second connection plate, a fixing member and a floor material. The supporting frame is respectively located in the joint part lower in which a plurality of bimetals. It is arranged leaving the interval corresponding to the width of bimetal to the width direction of the railway vehicle. In the supporting frame, the first accommodating groove having the predetermined depth is formed in the upper side. The first concatenated plate has the thickness corresponding to the depth of the first accommodating groove. The fixing member is penetrated and sets up in the second splice plates, bimetal, and the first concatenated plate and supporting frame.
