<p><P>PROBLEM TO BE SOLVED: To provide a mechanical opening/closing body stop device of an opening/closing apparatus which facilitates the operation of disposing a string-like body in an opening/closing body. <P>SOLUTION: When a shutter curtain 1 serving as the opening/closing body abuts on an obstacle during closing movement, the string-like body long enough to be elongated in the opening/closing direction of the shutter curtain 1 through the shutter curtain 1, and the shutter curtain 1 are coupled together by a mechanical coupling means 71 disposed in the shutter curtain, so that the shutter curtain 1 can stop the closing movement. The string-like body comprises a roller chain 32 which serves as a first string-like member, and a roller chain 80 which serves as a second string-like member coupled to the roller chain 32 in the length-direction midway portion of the roller chain 32 by means of sprocket wheels 76 and 77 and housed and disposed inside the shutter curtain 1. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
