<P>PROBLEM TO BE SOLVED: To provide a wind resistance structure of a shutter curtain, which solidly prevents the shutter curtain from slipping out and allows the shutter curtain to return to an original position smoothly and silently. <P>SOLUTION: A guide rail 5 is provided with a locking piece 5g, while a loose fit part of a guide groove 5a of a lower side connecting piece part 8c of a ventilation slat is provided with a punched-out recess part 8h. When a shutter curtain 2 is deformed to a flexural position, the locking piece 5g of the guide rail 5 falls into the punched-out recess part 8h, which is opposed to the depth direction of the guide groove 5a and has a first and a second sections 8j and 8k, so as to be locked to the first section 8j located adjacent to the back of the groove. The ventilation slat 8 is provided with a resin end member 11 having a guide surface 11c which guides the locking piece 5g in a direction to pull out of the punched-out recess part 8h in a process of allowing the shutter curtain 2 to deform from the flexural position to an original position, so that interference between the locking piece 5g and the second section 8k of the punched-out recess part 8h is restricted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
