PROBLEM TO BE SOLVED: To provide a connection structure of a frame member capable of suppressing clearances produced between frame members and suppressing positional displacements produced between the frame members even if a structure in which the adjacent frame members are allowed to directly abut on and connected to each other is adopted in the frame members of a door body W. SOLUTION: The first connection piece 3a of a connection member 3 is loosely fitted to the first frame member 1, and the second connection piece 3b of the connection member 3 is loosely fitted to the second frame member 2. By these loose fittings, the projection 10 of the connection member 3 is fitted to the slit groove 4a of the first frame member 1 and the slit groove 4b of the second frame member 2 and the first frame member 1 and the second frame member 2 are positioned close to each other. When the cut face 1c of the first frame member 1 is allowed to abut on the cut face 2c of the second frame member 2, the projection 10 is locked in a closed groove hole formed by these slit grooves 4a and 4b to position the first frame member 1 and the second frame member 2.
