PROBLEM TO BE SOLVED: To provide a laser processing head capable of reducing the probability that powder dust or the like may stick to a connection terminal when a fan for cooling the heat from a laser light source part is replaced, while keeping the sealed state of the laser light source part.SOLUTION: A laser processing head 1 is arranged with a removable connection terminal 41 belonging to a cable CA electrically connected with a fan 21, in the inside 12S of a second frame 12 adjacent to the inside 11S of a first frame 11 for holding a sealed state of a laser light source part 32. In other words, if the fan 21 is replaced by making use of the connection terminal 41 arranged in the inside 12S of the second frame 12, the sealed state of the laser light source part 32 in the inside 11S of the first frame 11 is kept at the time. While keeping the sealed state of the laser light source part 32, therefore, it is possible to replace the fan for cooling the heat from the laser light source part 32.SELECTED DRAWING: Figure 8 |
