PROBLEM TO BE SOLVED: To provide a laser beam processing device head, in which even if an outgoing optical head turns around a machining material, an optical fiber is not twisted and has long service life and can support the transmission of the laser beam and further, multi-dimensional automatic laser beam machining can smoothly be executed over for long life. SOLUTION: This head is composed of the optical fiber 2 for transmitting the laser beam from a YAG laser beam generator 1, and a rotary connector 3 composed of a housing inner cylinder 4, housing outer cylincler 5 and movable type dry bearing 6 at the connecting part with the outgoing optical head 7 conversion-irradiated with the laser beam transmitted with the optical fiber 2 while turning around a work tube 10 composed of a lens 8 and a reflecting mirror 9. |
