Patent number: 10284116Abstract: When an actuator using a conventional piezoelectric element is used as a general-purpose mechanical component, such as a linear actuator and an electric cylinder, the absence or weak constraint of a guide in the moving direction causes the problem that the moving direction of a moving member is changed or the moving member is rotated due to a change in the posture of the moving member by an external force. A restraint member presses a rectangular parallelepiped-shaped output shaft, which has high stiffness, thermal conductivity, and lubricity and to which a piezoelectric element is attached at one end, against a guide member so as to limit the degree of freedom to one degree, in order to realize a linear actuator, an electric cylinder, and a force generation device that can be used for general purposes and have a high straight movement property.Type: GrantFiled: December 24, 2014Date of Patent: May 7, 2019Assignee: MICROB CO., LTD.Inventor: Yoshiaki Hata
