Abstract
A laser machining device having a surface plate upon which a material to be machined is placed, a rail, a saddle, a garter, a horizontal carriage, and a laser nozzle. On it is attached: a machining trolley that causes the saddle to travel along rail, causes the horizontal carriage to travel horizontally along garter, irradiates laser light from laser nozzle towards a material to be machined, and cuts or welds the material. A cover is provided that covers substantially the entire surface of machining trolley and has an upper surface cover, a laser nozzle-side cover, a garter-side cover, and a side surface body. On a lower end side of the laser nozzle-side cover and the garter-side cover, there is a flexible light-blocking member for preventing laser light from leaking from a gap between the lower end section and the upper surface of the surface plate.
