<p>The objective of the present invention is to provide a rotary vibrator capable of easily realizing vibratory performance suitable for conveyance. The rotary vibrator (10) comprises a support unit (11), a vibration unit (12), and a vibratory structure (13) which is connected between the support unit (11) and the vibration unit (12). The vibration unit (12) is vibrated along a direction of rotating a circumference of an axis line (12x), and the vibratory structure (13) has multiple vibratory units (13A to 13C) at the circumference of the axis line (12x). Each of the vibratory units includes: a first elastic area (13a) which has a plate shape, is extended to the internal circumference at the same time being connected to the support unit (11) and is bending-deflected in the direction of rotating the circumference of the axis line (12x); a second elastic area (13b) which has a plate shape, is extended to the internal circumference at the same time being connected to the vibration unit (12), and is bending-deflected in the direction of rotating the circumference of the axis line (12x); a connection area (13c) to connect the internal end of the first elastic area (13a) and the internal end of the second elastic area (13b); and a piezoelectric unit (13p) to bending-vibrate at least one of the first elastic area (13a) and the second elastic area (13b), wherein the connection area (13c) configures a free end of a vibration.</p> |
