摘要 PROBLEM TO BE SOLVED: To provide a working machine, by which a shaking movement in the longitudinal direction of a Cable Bear (a registered trademark) can be inhibited while the Cable Bear is not projected from the front of a leader. SOLUTION: The working machine has the leader 10 installed to a machine body 11, a lifting-lowering body 20 lifted and lowered along the leader 10 and the Cable Bear 30 connected to the lifting-lowering body 20 and the machine body 11. In the working machine, a plurality of horizontal members 41 are fixed onto the front 10d of the leader 10 at intervals in the longitudinal direction and used as Cable-Bear stoppers 40, and the shaking movement in the longitudinal direction is inhibited by the collision of the Cable Bears 30 against the Cable-Bear stoppers 40 while the Cable bears are not projected from the front 10d.
