Patent ID: 8531091

Claim:
A holding device for a piezoelectric vibrator, comprising: a support member of a frame shape or a box shape for separately accommodating the piezoelectric vibrator; and a plate spring structure interposed between sides of the support member and the piezoelectric vibrator, wherein the plate spring structure comprises: a first plate spring member which extends from a proximal end fixedly bonded to one side of the support member so as to sandwich opposing sides of the piezoelectric vibrator across the opposing sides of the piezoelectric vibrator and is folded back to be fixedly bonded to the piezoelectric vibrator; and a second plate spring member which extends from a proximal end fixedly bonded to another side of the support member so as to sandwich the opposing sides of the piezoelectric vibrator across the opposing sides of the piezoelectric vibrator and is folded back to be fixedly bonded to the piezoelectric vibrator, and wherein the first plate spring member and the second plate spring member are integrated with each other at portions fixedly bonded to the piezoelectric vibrator.
