An apparatus for horizontally and intermittently withdrawing a cast steel strand from a horizontal mold of a horizontal type continuous casting machine, which comprises: at least one pair of pinch rolls (2A, 2B; 3A, 3B) for horizontally and intermittently withdrawing the cast steel strand from the horizontal mold by a plurality of cycles each comprising one pull for a prescribed period, one pause for a prescribed period and one push for a prescribed period; a driving device (4) for driving the at least one pair of pinch rolls (2A, 2B; 3A, 3B) through a driving force transmitter (6) in response to the above-mentioned one pull, one pause and one push in each cycle; and a brake (12) for imparting to the driving device (4) a braking force proportional to the number of rotations of the driving device (4) during the prescribed period of the one pull in each cycle so as to prevent the cast steel strand from being pulled over the prescribed period of the one pull in each cycle, the braking force of the brake (12) being smaller than the driving force of the driving device (4).
