PROBLEM TO BE SOLVED: To provide a bar steel sizing roller guide equipment with high product accuracy. SOLUTION: In order to obtain products with high accuracy, in bar steel steel sizing, it is desirable to adopt a roller driving system which performs sizing while giving a driving force to the sizing roller. However, it is difficult to install it near the rolling roll because the driving shaft to drive the roller poses an obstacle, and for this reason, it must be installed at a distant position. In this case, one or more pairs of sizing rollers 6 are installed to a guide box 2 via an eccentric roller holder 4 whose position can be adjusted to promote compactness of the equipment, and the rotation of the driving shaft 17 provided at a position away from the rolling roll is transmitted via a gear train R, thus overcoming the obstacle due to the existence of the driving shaft. Since this equipment performs sizing while drawing the bar steel by means of the driving sizing rollers, products of high accuracy can be obtained.
