To provide a fitting structure of a vibration-damping member for a balance spring, capable of effectively preventing dropping-off of the vibration-damping member from the balance spring.SOLUTION: A balance spring 8 includes a coil part 35a, and a vibration-damping member 9a includes a main part 42 and a pair of drop-preventing parts 43. With the main part 42 arranged inside of the coil part 35a in a radial direction and the pair of drop-preventing parts 43 arranged on both sides of the coil part 35a in an axial direction, the vibration-damping member 9a is mounted relative to the balance spring 8.SELECTED DRAWING: Figure 4
【課題】バランスばねからの制振部材の脱落を有効に防止できる、バランスばねに対する制振部材の取付構造を実現する。【解決手段】バランスばね8を、コイル部35aを有するものとし、制振部材9aを、本体部42と、1対の抜け止め部43とを有するものとする。本体部42をコイル部35aの径方向内側に配置し、かつ、1対の抜け止め部43をコイル部35aの軸方向両側に配置した状態で、制振部材9aをバランスばね8に対して取り付ける。【選択図】図4
