PROBLEM TO BE SOLVED: To provide a folding door device which is provided in an opening formed by posts or panel walls and cross beams constituting a zoning store fixture, in which adjacent two panel bodies are rotatable at an equal angle in a simple structure, which can be maintained in line when a door is closed so as to improve its appearance, and which can reduce cost.SOLUTION: A plurality of panel bodies 5, 6 are connected in a bendable manner via a connection rod 7. While a plate 31 having an approximately same external form as upper and lower end faces of the connection rod is interposed, a pair of interlocking members 8 are attached to the upper and lower parts rotatably via a vertical rotary shaft 32, respectively. An attachment part 33 to the panel body is formed in a side part of the interlocking members. A gear part 34 is protrusively provided on a semi-cylindrical outside surface on an opposite side. The gear parts of two pairs of the interlocking members facing each other on right and left sides are engaged with each other to form a hinge at an equal angle. A ball catch structure 35, which engages when the panel bodies are formed into a linear shape, is provided between the plates and the interlocking members. |
