PURPOSE: A center floor joining structure of a vehicle is provided to enhance binding strength by forming a closed space in connecting a center floor with a link tap and increasing the number of spot-welding of the center floor. CONSTITUTION: In a link tap(10) for connecting a center floor(1) and a side member(5) of a vehicle, a center floor joining structure of the vehicle widens a joining area of the center floor of the link tap, forms a closed section at the joined part of the link tap and the center floor, and makes a connection part of the link tap and the side member vertical. The link tap is joined to the center floor and then the side member is spot-welded to the side of the link tap three times. The closed space between the center floor and the link tap increases resisting power against stress applied from the outside.
