PURPOSE:To improve the shock resistance by providing a notch at a base so as to disperse a shock without concentrating it on a point. CONSTITUTION:Radii of R61, 62 are provided from a position from which the notch of the tuning fork type crystal oscillator is started to the end of base so as to make narrower the width of base gradually. Since the shock is dispersed when the oscillator is dropped in mistake, damage to the oscillator seldom occurs without a shock being concentrated on a specific part as a conventional oscillator. |
