<p>PROBLEM TO BE SOLVED: To improve durability of a device by following the movement of a mover to guide wires and pipes smoothly in a work machine having the mover freely moving in a work space. SOLUTION: In a parallel mechanism machine tool having a spindle head 2 supported through a universal joint 3 by six ball screws 4, a first revolving structure 15 is supported on a fixing ring 11 of a ceiling part 7a to revolve round a first shaft 13. A second revolving structure 20 is supported inside the first revolving structure 15 to revolve around a second shaft 17 orthogonal to the first shaft 13. A non-flexible pipe 25 is penetratingly inserted through the inside of the second revolving structure 20 to rotate around the pipe axis and slide in the direction of the pipe axis. A flexible pipe 38 is put in the connecting state between the non-flexible pipe 25 and the spindle head 2, and the wires and pipes are passed through a flexible tube 35, the non-flexible pipe 25 and the flexible pipe 38 and connected to the spindle head 2 inside a pipe cover 40.</p> |
