To provide an economical laser device rack, which is easily arranged and efficiently installed, and may be repeatedly used as well.

A laser device rack 1 comprises a mount body 2 for supporting a laser device therein, and an attachment member 3 for installation on natural round 32. The attachment member 3 is adapted to be detachably anchored on the natural ground 32, and is adjustable in length between the natural round 32 and the rack body 2. The rack body 2 is adjustable in height for the mounted laser device. The rack body 2 needs no welding but only anchoring for its installation differing from existing racks to save manual operations requiring various skills including welding in the installation of the rack 1. That laborsaving facilitates the total mounting work of a laser device on the rack 1 with great efficiency.
