驱动器
摘要：
本发明提供一种经由连接部件连接机电转换元件和驱动摩擦部件，而提高形状上的自由度的驱动器。驱动器(10)具备：压电元件(16)；固定在压电元件(16)的伸缩方向的端面(16A)的连接部件(20)；被安装于连接部件(20)的驱动轴(18)；以及摩擦卡合于驱动轴(18)的连接块(22)。平行地配置压电元件(16)和驱动轴(18)，连接部件(14)以设置于压电元件(16)和驱动轴(18)之间的作用点为中心摆动自如地被支撑。
摘要（英）：

The invention provides an actuator improved in shape freedom, by connecting an electro-mechanical conversion element to a driving frictional member via a connection member. The actuator (10) is provided with: a piezoelectric element (16); the connecting member (20) fixed to the end face (16A) in the expand/shrink direction of the piezoelectric element (16); a drive shaft (18) attached to the connection member (20); and a connecting piece (22) frictionally engaged with the drive shaft (18). The piezoelectric element (16) and the drive shaft (18) are disposed in parallel, and the connection member (14) is movably supported centering around a point of application provided between the piezoelectric element (16) and the drive shaft (18).
