PURPOSE: To manufacture a transducer rapidly and economically by forming the transducer and forming two branch parts separated by a spacer with a metal spring in a required shape.
CONSTITUTION: Edge parts 3A and 3B of two similar branch parts 2A and 2B in parallel shape of metal springs 10 and 11 are as wide as metal spacers 8 and 9 and the branch parts 2A and 2B are separated and laminated by the spacers 8 and 9. The spacers 8 and 9 and the edge parts 3A and 3B are mounted in coupling members 4 and 5 and become double tuning fork type lamination force transducers and vibrate in phase-opposing relationship in bending mode in response to the natural frequency load of amplitude according to a given force F in vertical direction. With this configuration, for example, a solid wire cut from a solid can be used, thus achieving a double tuning fork lamination force transducer that can be manufactured rapidly and economically.
