PROBLEM TO BE SOLVED: To provide a laser beam irradiating device to prevent an optical fiber from breaking without requiring any manual work. SOLUTION: The device is provided with a fixing fitting 3 to which an object 2 to be irradiated 2 is fixed, a laser beam irradiating head 7 to irradiate laser beam, an optical fiber 9 to transmit a laser beam to the laser beam irradiating head 7 and a coiling device 12 which is arranged surrounding the object 2 to be irradiated with a prescribed distance to the laser beam irradiating head 7 and coils the optical fiber 9 by turning integrally with the laser beam irradiating head 7. By this method, in irradiating the object to be irradiated with laser beam, the optical fiber is coiled to the coiling device with maintaining a prescribed distance with the laser beam irradiating head, as a result, the optical fiber is prevent from breaking. |
