    • PURPOSE:To improve the impact resistivity of a wrist watch with a reduction in the transmission level of a force applied from outside to a crystal resonator by fixing a cylinder type crystal resonator on the circumference of a cylinder section thereof from at least four directions with a plastic member. CONSTITUTION:A cylinder type crystal resonator 9 is tightened and fixed with plastic members 13 and 14 for fixing the crystal resonator. The plastic members 13 and 14 for fixing the crystal resonator use a soft plastic increase a damper constant so that the plastic member 14 for fixing the crystal resonator will be formed in a V shape to fix the crystal resonator 9 relatively soft and secure on a V-shaped inclined surface. Thus, a higher damper constant is obtained to enhance the impact resistivity.
    • 目的:为了提高手表的冲击电阻率,通过从至少四个方向将气缸型晶体谐振器从其至圆周方向固定在其圆柱形部分的圆周上,同时降低从外部施加到晶体谐振器的力的透射率水平, 塑料件。 构成:用于固定晶体谐振器的塑料构件13和14将圆筒型晶体谐振器9紧固并固定。 用于固定晶体谐振器的塑料构件13和14使用软塑料增加阻尼器常数,使得用于固定晶体谐振器的塑料构件14将形成为V形,以将晶体谐振器9固定在V 形倾斜面。 因此,获得较高的阻尼常数以提高冲击电阻率。
