PURPOSE: A guide roller device used in an automatic self-aligning roller stand is provided to adjust the meandering of a belt regardless of a driving direction of the belt. CONSTITUTION: A guide roller device includes a pair of guide rollers(50), a supporting shaft(40), a supporter(74), a sliding shaft, and a spring. The guide rollers(50) are installed vertical to a carrier roller, which supports both lower sides of a belt. A semi-spherical protrusion is protruded from lower ends of the guide rollers(50). The supporting shaft(40) is fixedly installed at both ends of an automatic self-aligning roller stand so as to support the guide rollers(50). The supporter(74) has a sliding hole. The supporter(74) is installed on the supporting shaft(40). The sliding shaft is slidably inserted into the sliding hole. The spring elastically supports the sliding shaft.
