PURPOSE:To facilitate attaching and detaching of a stay rod to and from a stay lever, by a method wherein a first link member having a long aperture is mounted to the lower end of the stay rod, a second link member, which can be freely inserted through the stay rod, is mounted and a hook part is formed on the stay lever. CONSTITUTION:A forked connecting member 9 is formed at a lower end of a stay rod 8, and a first coupling member 16 having a long aperture 15 surrounded with rectangular plates 11 and 14 is further situated. A hook part 17 on an upper end of a stay lever 6 is inserted through the long aperture 15 in the first coupling member 16, and the stay rod is turned rightward by 90 deg. to cause the hook part 17 to meet the long aperture at right angles. A second coupling member 21, through which the stay rod 8 can be freely inserted, is moved downward, the hook part 17 on the stay lever 16 is inserted through a long aperture 23 in the second coupling member 21, and the second coupling member 21 are fitted to cavities 19, 19' and 20, 20' formed in the first coupling member 16 to complete an engagement. |
