PROBLEM TO BE SOLVED: To reduce the number of components, to reduce the manufacturing cost and fitting cost, and to sufficiently attain the adhesiveness of elastic packings 26 and 33 in both directions when a door is fully closed. SOLUTION: The door 5A is suspended from a door suspension metal fixture 3A fixed to the outer wall 2A of the entrance 1A of a building via a pair of right and left rollers 8A and 8B and right and left suspension plates 6A and 6B journalled to the rollers. The elastic packings 26 and 33 are fitted to the lower face and inner wall face side of the door 5A respectively, and an inclined support section 4A is formed at the lower end section of the door suspension metal fixture 3A as a parent rail extended diagonally upward. An inclined recessed coupling groove 17 is formed on the support section 4A toward the inside from an upper end face 18, and a plurality of aluminum guard rails 21 and 21A having rail inclination sections 24a inclined to the floor surface direction F and the outer wall 2A side are inserted and fixed to the recessed coupling groove 17 so that the elastic packings 26 and 33 are closely stuck when the door is fully closed.
