PURPOSE: A guiding roller assembly of sliding door of automobiles, installed on one side of a sliding door, moves on a guiding rail to guide opening and closing of a slide door so as to prevent a vertical roller moving rotationally contacting a rail face from deviating from a supporting pin. CONSTITUTION: A guiding roller assembly of sliding door of automobiles is fixed on one side of the sliding door(1) and comprises a roller bracket(52), a horizontal roller(55) and the vertical roller(57) and a deviation preventing part(58)(59) on one end inserted into a guiding rail(6) of a car body. The roller bracket(52) has the horizontal roller(55) and the vertical roller(57) extending to a horizontal direction and a vertical direction, respectively. The horizontal roller(55) and the vertical roller(57) engage rotatably with a horizontal roller shaft(54) and a vertical roller shaft(56), respectively, so as to move rotationally guided by guiding faces(62)(64) of the guiding rail(60). The deviation preventing part has a ring shaped protrusion(58) formed by the external surface of the vertical roller shaft(56) and a ring shaped groove(59) formed by the internal surface of the vertical roller(57) so as to accept the ring shaped protrusion(58) when the vertical roller(57) engages with the vertical roller shaft(56), and prevents the vertical roller(57) from deviating from the vertical roller shaft(56).
