A joint unit pivotably coupled to a tip end part of a main arm member of a Scott Russell mechanism is pivoted in two ways. A Scott Russell mechanism device (1) pivotably couples a main arm member (41) and a sub arm member (51) to each other, as well as it pivotably couples a joint unit (60) to a tip end part (41c) of the main arm member (41). Moreover, by providing a pivoting mechanism unit (80) to the main arm member (41), as well as providing a fourth motor (M4) and a drive transmission mechanism unit (90) to the sub arm member (51), the Scott Russell mechanism device (1) can switch between pivoting the joint unit (60) associatively a change of a coupling angle of the arm members (41 and 51) and pivoting the joint unit (60) by the drive of the fourth motor (M4). |
