PROBLEM TO BE SOLVED: To provide a joint device for a floor using a joint cover, efficiently preventing the breakage of a connection part while efficiently preventing the occurrence of distortion to the connection part to cause waviness even if a plurality of steel plates or stainless steel plates are welded to form the joint cover. SOLUTION: The joint device for the floor covers the joint part between right and left floor skeletons provided through the joint part, using the joint cover formed by connecting, by welding, a plurality of joint cover bodies made of steel plates or stainless steel plates. The connection part of the joint cover body is prevented from being distorted by forming fitting parts of pulse wave shape or dovetail groove like corrugated shape and connecting the angular parts of the fitting parts by spot welding.
