PROBLEM TO BE SOLVED: To provide a laser line projecting mechanism where a wire rod resistant to vibration and impact can be used for a feeder to the laser oscillator of a laser marking device, only a lens is disposed in a lens assembly equipped with a gyro function in order to realize the miniaturization and lightweight of the laser marking device, and the laser oscillator is fixedly disposed in an arbitrary member free from rocking, and which can project the laser line in a horizontal and/or vertical direction even in such disposed form. SOLUTION: A parallel lens body 1 where a plurality of lens bodies constituted so that the cross section of a surface on a projection side, at least, may be protrusively arc-shaped are arranged side by side is used as the lens disposed in a pendulum body 2 supported to freely rock, and a laser beam 6 emitted from the laser oscillator disposed at the arbitrary part of the laser marking device is directly and indirectly guided to the parallel lens body 1.
