Abstract
A parallel link mechanism includes a proximal end member and three or more link mechanisms. Three or more link mechanisms connect the proximal end member to a distal end member. In three or more link mechanisms, a first center axis of a first revolute pair unit and a second center axis of a second revolute pair unit intersect at a spherical link center point. Fifth center axes of respective fifth revolute pair units of three or more link mechanisms overlap each other and intersect with the spherical link center point.
