摘要： A piezoelectric drive device (10) includes a piezoelectric actuator (20) including a vibrator (21) having piezoelectric elements, and a rotor (30) that is rotated in one specific direction by the vibrator (21); and a rotation transfer device (40) that transmits rotational energy from the rotor (30) to a driven rotating body, includes an elastic device (42) that can store rotational energy transmitted from the rotor (30) as elastic energy, and a rotation limiting device (43) that has a drive wheel (431) and a driven wheel (435) that rotates in conjunction with rotation of the drive wheel (431), allows the driven wheel (435) to rotate a specific angle in conjunction with rotation of the drive wheel (431), and restricts driving the drive wheel (431) from the driven wheel (435) when the driven wheel (435) rotates this specific angle. The elastic device (42) and the rotation limiting device (43) are disposed so that rotational energy transmitted from the rotor is transmitted through one to the other of the elastic device (42) and the rotation limiting device (43); and the rotor (30), the elastic device (42), and the rotation limiting device (43) render a serial path for transmitting rotational energy.

摘要： A pencil type vibration wave driven motor having a vibration member for generating a vibration wave upon energization of a piezo-electric element is disclosed. The motor further has a compression member for pressing the rotor against the vibration member.
The compression member is arranged between the rotor and an output member engaged with the rotor.
The output member is supported by a supporting portion provided to the vibration member through a bearing.
Therefore, a compression force of the compression member is applied between the rotor and the vibration member without being reduced.摘要翻译： 公开了一种铅笔式振动波驱动电动机，其具有用于在压电元件通电时产生振动波的振动部件。 电动机还具有用于将转子压靠在振动部件上的压缩部件。 压缩构件设置在转子和与转子接合的输出构件之间。 输出构件由通过轴承设置到振动构件的支撑部支撑。 因此，压缩构件的压缩力被施加在转子和振动构件之间而不被减小。

摘要： A stator consists of a piezoelectric vibrator or piezoelectric vibrators of piezoelectric ceramic and so on are put between a long metal block and a short metal block, which are fixed with the both screws of bolt by means of screw. When a high frequency alternative current voltage is applied to the piezoelectric vibrator or piezoelectric vibrators, elliptic vibrator of compounded vibration, progressive vibration and so on, which is compounded torsional vibration due to the screws of the bolt with longitudinal vibration due to the expantion and contraction of the piezoelectric vibrator or piezoelectric vibrators, is generated on the end surface and the side surface of the stator. A driven member is engaged on the end surface or the side surface of the stator and is driven by the elliptic vibration.

摘要： A vibrating body (2) for driving a driven body includes a piezoelectric element (22), an abutting part (23), and an electrode arrangement on a surface of the piezoelectric element comprising an elongated central electrode (22A) and two sets of electrode pairs (22B;22C), the electrodes of each pair being arranged diametrically opposed to each other and the sum of the length of the electrodes of each pair being less than or equal to the length of the central electrode. With this structure, the drive direction of the driven body can be changed by switching between application of the voltage to the central electrode and one electrode pair and application of the voltage to the central electrode and the other electrode pair. The vibrating body is applied as a driving element in a rotary drive device to drive a time indicator hand of a timepiece or a centrifugal fan of an air blower or a tire.
