Abstract: To provide a vibration conversion apparatus capable of reducing occurrence of cracks although using a longitudinal vibration converter for obtaining a torsional vibration. The vibration conversion apparatus comprises: a first longitudinal vibration converter and a longitudinal-torsional transducer having a one-wavelength torsional vibrator portion and a first flexural resonator portion. The first flexural resonator portion is interposed between the first longitudinal vibration converter and the one-wavelength torsional vibrator portion. The first flexural resonator portion is configured such that when a longitudinal vibration generated by at least the first longitudinal vibration converter is received from one end of the first flexural resonator portion, the first flexural resonator portion is bent and imparts a rotational force from the other end of the first flexural resonator portion to the one-wavelength torsional vibrator portion.
