The present invention relates to a noise reduction type roller track and, specifically, to a noise reduction type roller track which is structurally simple and reduces noise generated due to contact with different materials. The noise reduction type roller track includes: a box-shaped frame (11) with open upper surface; an impact absorbing groove (112) formed on the side of the frame (11) to face the inner side; a separation prevention wing (111) formed at an upper end on the side of the frame (11) to face the inner side; a fixing groove (114) formed in the lower part of the separation prevention wing (111); a roller frame (12) fixed by being inserted into the fixing groove (114); a roller (13) fixed to the roller frame (12) by a rotation pin (131); and a support unit (15, 17) connected to the front side of the frame (11). The roller frame (12) is formed of a nonmetal material same as or similar to the roller (13), and both ends of the rotation pin (131) are separated from the inner surface on the side of the frame (11). |
