Kind Code:
A1
Abstract:
This link actuation device (1) has link hubs (2, 3) arranged respectively on the input/output sides, and multiple link mechanisms (4A, 4B). The link mechanisms (4A, 4B) are three-joint chain link mechanisms comprising four revolute pairs, wherein end links (5, 6) are connected in a rotatable manner to the link hubs (2, 3), and the input-side and output-side end links (5, 6) are connected in a rotatable manner to a central link (7). The revolute pair axes (O1A, O1B, O2A, O2B) of the link hubs (2, 3) and the end links (5, 6) are inclined toward the opposing link hubs (3 2). Spherical link centers (P1, P2) are located between a posture change center (O) and the link hub surfaces (F1, F2).
