Abstract
An operation device including a combination of a rotation unit and a linear motion unit. The rotation unit includes a link actuation apparatus and a rotation actuator. The link actuation apparatus includes a proximal end side-link hub, and a distal end side-link hub coupled thereto through three or more link mechanisms so as to enable a varying attitude relative thereto. The link actuation apparatus is mounted to an output shaft of the rotation actuator such that a central axis of the proximal end side-link hub forms an angle relative to an axis of rotation of the rotation actuator. The linear motion unit includes a linear actuator serving as an output portion thereof, and the rotation unit is mounted to this linear actuator.
