    • A screw-fixing implement which is low in cost and has a high reliability, a resonator device having the screw-fixing implement and having a characteristic adjusting function, a filter, an oscillator, and a communication device each containing the resonator device, and a method of adjusting a characteristic of the resonator device are provided. A nut 2 for fixing a characteristic-adjusting screw 1 is provided with a concave portion d in the vicinity to the axis of the fixing nut 2 and concaved in the thickness direction. A spring-washer 3 is provided with a convex portion p which is engaged with the concave portion d of the screw-fixing nut 2. The spring-washer 3 is sandwiched between a panel 4 and the screw-fixing nut 2. Then, the characteristic adjusting screw 1 is turned under an appropriate load. After the characteristic is adjusted, the screw-fixing nut 2 is tightened till the spring washer 3 is completely broken. Thus, these members are locked.
    • 具有低成本且高可靠性的螺钉固定器具,具有螺钉固定器具的谐振器装置,具有特征调节功能,滤波器,振荡器以及各自包含谐振器装置的通信装置,以及 提供了调节谐振器装置的特性的方法。 用于固定特性调节螺钉1的螺母2在固定螺母2的轴线附近设置有凹部d,并且在厚度方向上凹陷。 弹簧垫圈3设置有与螺钉固定螺母2的凹部d接合的凸部p。 弹簧垫圈3夹在面板4和螺钉固定螺母2之间。 然后,将特性调节螺钉1在适当的载荷下转动。 在调整特性之后,拧紧螺钉固定螺母2直到弹簧垫圈3完全断裂。 因此,这些成员被锁定。
