Abstract

In a parallel link mechanism (9), a distal end side link hub (13) is coupled to a proximal end side link hub (12) via three link mechanisms (14) such that a posture of the distal end side link hub (13) can be changed. Each link mechanism (14) includes a proximal side end link member (15), a distal side end link member (16), and a center link member (17), and forms a quadric chain link mechanism (14) composed of four revolute pairs. A singular point occurs when a central axis (QA, QB) of the proximal or distal end side link hub (12, 13) and a central axis (O2, O3) which is a rotation axis of a revolute pair section of the proximal or distal side end link member (15, 16) and the center link member (17) coincide with each other. An axis angle (γ) of the center link member (17) is specified such that a posture in which the singular point occurs is avoided.
