PURPOSE:To easily enable the highly accurate adjustment in an irradiation direction, by a method wherein one axis crossing emitted laser beam in a vertical direction is matched with the bench mark of a laser beam emitting side and said bench mark is used as a fulcrum to revolve laser machinery. CONSTITUTION:Laser equipment 1 has a laser beam emitting apparatus 2 mounted therein and a support shaft 3 is mounted to the front end lower part of said machinery 1 and a support leg 4 is mounted to both sides of the rear end thereof. The support shaft 3 is mounted so that the axis thereof is allowed to coincide with one axis crossing the beam (a) emitted from the laser beam emitting apparatus 2 in a vertical direction. The end of the support shaft 3 is matched with the bench mark A preliminarily provided to the equipment arrangement side and said bench mark is used as a fulcrum to revolve the laser equipment 1 left or right to allow the irradiation direction of laser beam (a) to be precisely matched with an irradiated body C erected on the bench mark B in an arrival side.
