In order to lock the row floors (2, 3, 4) in the telescoping seating system, there is provided a row floor-locking device (14) which comprises a pair of driven sprockets (11) each of which is attached to left and right edge portions of the back side wall (2c, 3c) of the next lower row, a pair of chains (12), a gear wheel (15) mounted coaxially with the pair of sprockets (11), a rack (24) engagable with the gear wheel (15) and driving means for engaging the rack with the gear wheel (15).
