<p><P>PROBLEM TO BE SOLVED: To prevent a torsion coil spring from slipping out of a flap body, when installing the flap body on an installation object. <P>SOLUTION: A cutout part 53 is formed to run along one side of forming a linear base end part of the flap body 43, to form a bar-shaft 49 on at least one end and to have a space between the bar-shaft 49 and the flap body 43 in the flap body 43 around the bar-shaft 49. A locking part 57 having an insertion hole 55 between the cutout part 53 and a tip part of the flap body 43, and a stopper part 61 between the cutout part 53 and the locking part 57, are integrally erected on a reverse surface of the flap body 43. The torsion coil spring 65 energizing the flap body 43 is inserted into the insertion hole 55 of the locking part 57 in a state of positioning its one end part 65a inside the flap body 43 to the stopper part 62 by loosely fitting the bar-shaft 49 in an annular part 67, and the torsion coil spring 65 is regulated from falling off from the bar-shaft 49 by the stopper part 61. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
