PROBLEM TO BE SOLVED: To reduce and prevent noise caused by the mutual contact of lattices with simple structure even if an impact is applied to a panel body when opened/closed. SOLUTION: A gate door 1 has a plurality of lattice members 5, 6 arranged to cross in front and in the rear within a frame body 4 framed in square shape with an upper frame 4a, a lower frame 4b and right and left vertical frames 4c. The lattice members 5, 6 are crossed in front and in the rear at a plurality of intersections, and each intersection is provided with a connection part where the lattice members 5, 6 are connected to each other, or a non-connection part where the lattice members 5, 6 are not connected to each other. The lattice members 5, 6 at the connection part are connected to each other through a space holding part 11, and a clearance 12 is formed between the lattice members 5, 6 at the non-connection part.
