The present invention relates to a roller device for a slide door of a vehicle, capable of stably sliding without shaking even if the roller device does not increase the number of rollers. More specifically, the roller device for a slide door of a vehicle includes: a guide rail installed in the longitudinal direction on the lower surface of a door mounting unit which is open in a vehicle body and guiding opening and closing of a slide door; a fixing unit installed and fixed to the lower part of the slide door; and first and second rollers installed in the fixing unit to rotate and rolling and moving along the guide rail when the slide door is opened and closed. The guide rail includes: a first contact surface which is in contact with one among the first roller and the second roller; and a second contact surface which is inclined at an angle of inclination smaller than 90° to the first contact surface, wherein the other one among the first roller and the second roller is in contact with the second contact surface. The first roller and second roller are installed to be inclined in the fixing unit to have an angle of inclination that is the same as that of the first contact surface and that of the second contact surface.
