<P>PROBLEM TO BE SOLVED: To provide a structure which allows the installation/uninstallation of a torsion coil spring with easy work when installing/uninstalling the torsion coil spring to/from an opening/closing cover, and wherein the spring is hard to come off from a locking part during the installation/uninstallation work. <P>SOLUTION: In this opening/closing cover 80, when a first arm part 92 is positioned just before a locking groove 86 formed in an opening part 83 while fitting a coil part 91 onto a closing shaft 82 in a state that the first arm part 92 is inserted in the opening part 83 formed in a side plate 80B, the first arm part 92 abuts on a fixing end face 84 of the opening part 83 and the other end face 85 facing to the fixing end face 84, so that tension is applied to the coil part 91. When pushing in the coil part 91 as it is, the first arm part 92 is locked in the locking groove 86, and the spring 90 is installed to the opening/closing cover 80. <P>COPYRIGHT: (C)2013,JPO&INPIT |
