PROBLEM TO BE SOLVED: To improve efficiency in assembling work and to enable reduction in size and weight.SOLUTION: A latch shaft 5 has a shape that has a flange, capable of penetrating a surface side first shaft hole 32 and a shaft hole 64 of a latch 6 from the surface side of a cover plate 3. A back plate 4 includes: a rear side first shaft hole formation part 41 which forms a rear side first shaft hole 411 in which a small diameter shaft part 53 of the latch shaft 5 penetrating the shaft hole 64 of the latch 6 is inserted in retaining manner; a rear side second shaft hole formation part 42 which forms a rear side second shaft hole 421 in which a second shaft part 72 formed at other end part of a pole 7 is rotatably inserted; and a threaded hole formation part 44 which is near the rear side second shaft hole formation part 42, to form a single threaded hole 441 in which a single bolt 15A is screwed. It has a shape that does not expand as far as a portion corresponding to positions of a plurality of other bolts 15B, 15C. 【課題】組み立て作業の効率化を図ると共に、小型軽量化を可能にする。【解決手段】ラッチ軸５は、カバープレート３の表面側から表側第１軸孔３２及びラッチ６の軸孔６４を貫通し得る鍔付き形状とする。バックプレート４は、ラッチ６の軸孔６４を貫通したラッチ軸５の小径軸部５３が抜止め挿入される裏側第１軸孔４１１を形成する裏側第１軸孔形成部４１と、ポール７の他端部に形成した第２軸部７２が回転可能に挿入される裏側第２軸孔４２１を形成する裏側第２軸孔形成部４２と、裏側第２軸孔形成部４２の近傍にあって、単一のボルト１５Ａが螺合する単一のねじ孔４４１を形成するねじ孔形成部４４とを有すると共に、他の複数のボルト１５Ｂ、１５Ｃの位置に対応する部位まで拡大しない形状を呈する。【選択図】図４
