<P>PROBLEM TO BE SOLVED: To provide a multi-axis robot arm which can suppress the deformation of a linear member widely even if a posture of an arm is changed. <P>SOLUTION: The multi-axis robot arm 1 includes: the arm 8 including arm members 10 and a joint shaft 11 for coupling the arm members 10 with each other; and the linear member 17 of which the tip side and the base side are supported to the arm member 10. The multi-axis robot arm 1 further includes a follow-up support device 20 that is provided in an arm member 10C supporting the base side of the linear member 17 and supports the base side of the linear member 17 so as to follow up the movement of the arm 8. The follow-up support device 20 includes: an arm fixing part 21 fixed to the arm member 10C; a linear member supporting part 22 for supporting the linear member 17; follow-up movable parts 23, 25 including a plurality of follow-up movable shafts 25 and coupling the fixing part 21 with the linear member supporting part 22; and a follow-up drive means 27 for driving the follow-up movable shafts 25. <P>COPYRIGHT: (C)2013,JPO&INPIT |
