PROBLEM TO BE SOLVED: To provide an opening/closing body device which is formed of a blocking means for blocking an entrance, a support means such as a center pillar extended from the entrance, a first shielding means such as a shutter curtain unreeled from the entrance, and a second shielding means such as a fire door arranged adjacently to the support means and the first shielding means, wherein the second shielding means and the blocking means are prevented from interfering with each other in their operations. SOLUTION: The opening/closing body device is formed such that both the blocking means and the fire door do not hinder the mutual operations by taking into consideration movable ranges and operating directions of the blocking means and the fire door. For example, both the blocking means and the fire door are arranged such that their movable ranges do not interfere with each other. Alternatively if the blocking means makes contact with the fire door, part of the blocking means releases a contact stress by its rotational motion, or part of the blocking means is made of an elastic member to release the contact stress by virtue of elastic deformation of the elastic member.
