钟表的擒纵机构
摘要：
本发明提供一种钟表的擒纵机构，在钟表的擒纵机构中，为了提高从擒纵轮向擒纵叉的能量传递效率，钟表的擒纵机构(1)具有：擒纵轮(10)，其围绕轴心(C1)旋转并具有15个齿部；擒纵叉(50)，其摇动并且具有切换所述擒纵轮(10)的旋转和停止并通过与所述齿部(11)接触而从所述擒纵轮(10)接受转矩的出瓦(56)以及进瓦(55)，并且仅通过所述擒纵叉(50)，使所述擒纵轮(10)和摆轮(圆盘钉60)进行授受转矩，除所述进瓦(55)和所述出瓦(56)外所述擒纵叉(50)还具备第3瓦(58)(转矩接受部件)，其从所述擒纵轮(10)的凸部件(13)接受转矩。
摘要（英）：

To improve the transmission efficiency of energy from an escape wheel to a pallet in an escapement for a timepiece. An escapement 1 for a timepiece includes an escape wheel 10 that rotates about a shaft center C1 and a pallet 50 that oscillates. The escape wheel 10 includes fifteen teeth. The pallet 50 includes an entry pallet jewel 55 and an exit pallet jewel 56 that switch the rotation and stop of the escape wheel 10 and receive torque from the escape wheel 10 by contacting the teeth. The escape wheel 10 and a balance (an impulse pin 60) apply and receive torque only via the pallet 50. The pallet 50 includes a third pallet jewel 58 (a torque applying and receiving member) that receives torque from a convex portion 13 of the escape wheel 10 in addition to the entry pallet jewel 55 and the exit pallet jewel 56.
