PROBLEM TO BE SOLVED: To provide an open-close device for an entrance, by which the mechanical sound of the entering-leaving treatment of a multistory parking tower is shielded and the operation of entering-leaving cars can be confirmed on a riding-in field. SOLUTION: An opening and closing panel frame body 14 is installed into the opening section 3 of the entrance 30, the panel frame body 14 on the surface of the panel frame body 14 is formed of a sight-through member 37, the first sealing member 27 fast stuck on the surface side of the panel frame body 14 is mounted on the wall surface 11 of the opening section 3, the second sealing member 28 with an expansion and contraction means is secured on the rear of the panel frame body 14, the first sealing member 27 and the second sealing member 28 are stuck fast when the opening section 3 is closed, and the noises of a parking device are shielded while the delivery of cars on the riding-in field 2 can be viewed from a panel surface 36 regarding the open-close device 15 for the multistory parking tower 1, which has a plurality of floors of parking chambers X and Y adjacent to a lifting-lowering space E and a lifting-lowering lift 4 lifted and lowered in the space E and in which a traversing tray traversable to the parking chambers X and Y is arranged and the cars are delivered by the lift 4 and the traversing tray.
