PROBLEM TO BE SOLVED: To selectively improve the adhesion of a plurality of strips in a closed state and selectively improve the separability of a plurality of strips in an open state in a goodwill type curtain door. SOLUTION: A goodwill type curtain door 10 is a plurality of soft strips 40 hanging by its own weight, which can be curved when an external force acts in an out-of-plane direction, and a soft magnet bar 50 having a soft longitudinal shape. It is configured by being held by the holder 60 of. When the external force is not applied, the plurality of strips 40 are substantially brought into close contact with each other by the magnetic force of the magnet bar 50, whereby the strip closed state is realized, while when the external force is applied, a plurality of objects are formed. The strip 40 of the strip 40 is pushed away, whereby the strip open state is realized. The holder 60 has a flexural rigidity directivity having a characteristic that the bending rigidity is lower around the neutral axis extending in the width direction and around the neutral axis extending in the thickness direction.
