Description

管状作動要素36の下端は、切欠き部により部分的に短くなっており、当該切欠き部は、作動要素の回転中央軸心に垂直な第1面40a、及び作動要素の回転中央軸心に平行な第2面40bを有する。作動要素36の下端から見ると、第2面40bは、作動要素の円形断面において弦を形成している。 The lower end of the tubular actuating element 36 is partially shortened by a notch, which is located on a first surface 40a perpendicular to the center of rotation of the actuating element and at the center of rotation of the actuating element. It has a parallel second surface 40b . Seen from the lower end of the actuating element 36, the second surface 40b forms a string in the circular cross section of the actuating element.

作動要素36が初期位置にあるとき、第2面40bは、外側カプリング部30のカラー部41に当接している。この初期位置において、外側カプリング部30は、内側カプリング部29と結合している。これら2つの係合部29、30間のトルク伝達接続は、外側カプリング部30にばね荷重をかけることによって達成することができる。したがって、外側カプリング部30は、ブッシュ42に対して変位可能に配置されており、ブッシュ42は、当該ブッシュの端壁44と外側カプリング部30との間に設けられた圧縮ばね43を含む。本実施形態において、ブッシュ42は、スピンドル22のシャフト端22aに続く当該スピンドルのねじ部に配置されており、端壁44は、当該スピンドルのシャフト端22aから最も離れた位置に配置されている。 When the actuating element 36 is in the initial position, the second surface 40b is in contact with the collar portion 41 of the outer coupling portion 30. At this initial position, the outer coupling portion 30 is coupled to the inner coupling portion 29. The torque transmission connection between these two engaging portions 29, 30 can be achieved by applying a spring load to the outer coupling portion 30. Therefore, the outer coupling portion 30 is displaceably arranged with respect to the bush 42, and the bush 42 includes a compression spring 43 provided between the end wall 44 of the bush and the outer coupling portion 30. In the present embodiment, the bush 42 is arranged at the threaded portion of the spindle following the shaft end 22a of the spindle 22, and the end wall 44 is arranged at the position farthest from the shaft end 22a of the spindle.

ケーブルを引っ張ることにより作動要素36が回転すると、第2面40bが、ブッシュの端壁44へ向かって外側カプリング部30を変位させることにより、圧縮ばね43を圧縮する。作動要素36が所定位置まで回転すると、トルク伝達接続が妨げられる程度まで外側カプリング部30が変位する。 When the actuating element 36 rotates by pulling the cable, the second surface 40b compresses the compression spring 43 by displacing the outer coupling portion 30 towards the end wall 44 of the bush. When the actuating element 36 rotates to a predetermined position, the outer coupling portion 30 is displaced to the extent that the torque transmission connection is hindered.
