<P>PROBLEM TO BE SOLVED: To provide an opening/closing body stooping device for an opening/closing apparatus in which, even if a direction for a take-up member to take up a string-like member with accumulated pressure of an elastic member is a rotating direction of a rotary member for engaging an engaging part of an engage member and teeth of the rotary member, when an opening/closing body is to perform closing movement, the string-like member can be taken up by the take-up member. <P>SOLUTION: A lock wire 36 that is a string-like member is fed out of a take-up reel 37 that is a take-up member by the closing movement of a shutter curtain 1 that is an opening/closing body. When the shutter curtain 1 is abutted to an obstacle or the like, an engaging part 53 of an engage member 50 is engaged to teeth 35A of a rotary member 35. Even if a direction for the take-up reel 37 to take up the lock wire 36 with accumulated pressure of a return spring 39 is a rotating direction of the rotary member 35 for engaging the engaging part 53 and the teeth 35A, the engaging part 53 is disengaged from the teeth 35A by disengagement energizing means 90 including a torsion coil spring 57 or the like. <P>COPYRIGHT: (C)2013,JPO&INPIT |
