To provide a setting stem interlocking mechanism allowing a user to pull out a setting stem to a first stage position and a second state position, even when a clutch wheel and a setting wheel butt on each other and even when the setting wheel and a gear of a wheel train for time setting butt on each other.SOLUTION: A setting stem interlocking mechanism 10 includes a setting stem 10 that can be pulled out from a 0 stage position to a first stage position and a second stage position, a setting lever 20 rotating in response to movement of the setting stem 10, a yoke 30 for moving a clutch wheel 18 in an axial direction corresponding to the rotation of the setting lever 20, a setting wheel 50 to be engaged with the clutch wheel 18 at the first stage position and the second stage position, and a switching link 40 engaged with the setting lever 20 and moving the setting wheel 50 between the first stage position and the second stage position according to rotation positions of the setting lever 20. The yoke 30 includes an elastic piece 35 that can be elastically deformed, between an engagement part 36 engaged with the clutch wheel 18 and a support point C2, and the switching link 40 includes a pulling-side part 42a being elastically deformable within a range from a part where the setting wheel 50 is supported, to a groove 41 with which the setting lever 20 is engaged.SELECTED DRAWING: Figure 3 【課題】つづみ車と小鉄車とが突き当たった場合及び小鉄車と時刻合わせ用の輪列の歯車とが突き当たった場合も巻真を１段位置及び２段位置まで引き出すことができる。【解決手段】巻真連動機構１０は、０段位置から、１段位置及び２段位置まで引き出し可能の巻真１０と、巻真１０の移動に応じて回転するおしどり２０と、おしどり２０の回転に対応して、つづみ車１８を軸方向に移動させるかんぬき３０と、１段位置及び２段位置においてつづみ車１８に噛み合う小鉄車５０と、おしどり２０に係合し、の１段位置と２段位置との間で、おしどり２０の回転位置に応じて小鉄車５０を移動させる切替リンク４０と、を備え、かんぬき３０は、つづみ車１８に係合した係合部３６と支点Ｃ２との間に弾性変形し得る弾性片３５を有し、切替リンク４０は、小鉄車５０が支持された部分とおしどり２０が係合した溝４１との範囲で弾性変形し得る引き側部分４２ａを有する。【選択図】図３
