PROBLEM TO BE SOLVED: To reduce labor of fractionation work in disposing an inner door by making one of two spindle pins sinkable by a spring member made of synthetic resin into an upper or lower edge of the inner door. SOLUTION: The base end part 18b of an upper spindle pin 18 is positioned in a recess part 24 on the left end of a patch 9. A knob part 18c is exposed outside from a cut-off part on the left end of the recess part 24. The lower end of the base end part 18b of the upper spindle pin 18 is positioned above a main body 16a of a spring member 16 made of synthetic resin equipped in the recess part 24. The upper spindle pin 18 is usually protruded from the upper edge of the patch 9 and the knob part 18c is pressed own against the energizing force of the spring member 16 so as to be sinkable inside the patch 9. Thus, fractionation work becomes easier even when the inner door 5 is to be disposed of. |
