Abstract
A distal end side link hub is coupled to a proximal end side link hub via three or more link mechanisms. Each link mechanism has a proximal side end link member, a distal side end link member, and an intermediate link member. The proximal side end link member has a bent portion and rotation shaft mounting portions. A rotation shaft is mounted to the rotation shaft mounting portion. A bevel gear, forming a part of a gear mechanism for transmitting rotary motion of a posture control actuator to the proximal side end link member, is mounted on the rotation shaft mounting portion and disposed in a space between two virtual planes obtained by extending a radially inner edge and a radially outer edge of one end of the bent portion in a longitudinal direction of the rotation shaft mounting portion.
