PROBLEM TO BE SOLVED: To reinforce an operation lever and a reset lever, and to attach them by a simple structure without causing wobbling.SOLUTION: An operation lever 5 is composed of a pair of lever members, and attached to a handle rotating shaft 32 of a handle attachment part 14 so as to be turnable. One end side is accommodated in an operation lever accommodation part 30 at both sides of an operation handle 3 so as to be releasable, and the other end is extended up to a press rod insertion part 19. A reset lever 6 is attached to a shaft 53 which is arranged on a back face of the operation handle 3 in parallel with the handle rotating shaft 32 at the other end side of the operation lever 5 rather than the handle rotating shaft 32 of the handle attachment part 14 at an intermediate part of the operation lever 5 via a spacer ring so as to be turntable.SELECTED DRAWING: Figure 14
【課題】作動レバー、リセットレバーを補強し、簡単な構造でがたつきなく取り付ける。【解決手段】作動レバー５は一対のレバー部材からなり、ハンドル装着部１４のハンドル回転軸３２に回動可能に取り付けられ、一端側が操作ハンドル３両側の作動レバー収納部３０に離脱可能に収納されて、他端が押棒挿通部１９に延ばされる。リセットレバー６は操作ハンドル３の背面上に作動レバー５の中間部でハンドル装着部１４のハンドル回転軸３２よりも作動レバー５の他端側にハンドル回転軸３２と平行に架設される軸５３にスペーサリングを介して回動可能に取り付けられる。【選択図】図１４
