Abstract
PURPOSE:To reduce the displacement of a fixed part and to decrease the loss of oscillation due to fixation, by providing a part of rest of etching formed at one side of an arm to other side of the arm through extension relatively. CONSTITUTION:To obtain a symmetrical oscillation left and right, a part of rest of etching is provided on another side through extension, allowing to made the bending of an arm 11 easy. Left and right symmetrical oscillatin distribution can be obtained by regulating the size (b) of a correction section 13 to 20-60% of te rest size (a) of etching. With the constitution like this, since the displacement at the fixed part of a quartz oscillator is small, the oscillation loss is less and high pressure resistance and impact resistance can be increased.
