Claims (1)
【実用新案登録請求の範囲】[Scope of utility model registration request] 脱進機構を用いずにヒゲゼンマイと天輪が一体 であり、ヒゲゼンマイの長さを調整することによ り、その振動周期を調整する時間調整機において 、天輪の中心軸の両端を一定範囲に固定したこと を特徴とするヒゲゼンマイの時間調整機構。 In a time adjustment machine where the balance spring and the balance wheel are integrated without using an escapement mechanism, and the vibration period is adjusted by adjusting the length of the balance spring, both ends of the central axis of the balance wheel are kept within a certain range. A balance spring time adjustment mechanism characterized by being fixed.
