A continuous casting mold in which a pair of mold shorter sides (2a, 2b) are exchangeably sandwiched between a stationary mold longer side and a movable mold longer side, comprising: first and second drive mechanisms (7a, 7b) disposed in two places in the left-right direction on the upper side of one of the stationary mold longer side and the movable mold longer side and moving the movable mold longer side relative to the stationary mold longer side; third and fourth drive mechanisms (7c, 7d) disposed in two places in the left-right direction on the lower side of said one of the stationary mold longer side and the movable mold longer side and moving the movable mold longer side relative to the stationary mold longer side(la); characterized in that the mold further comprises: a first connecting shaft operatively connecting the first drive mechanism and the third drive mechanism disposed in the top-bottom direction; and a second connecting shaft operatively connecting the second drive mechanism and the fourth drive mechanism disposed in the top-bottom direction, wherein when the first connecting shaft is rotated about its axis, the first and third drive mechanisms (7a, 7c) operate in conjunction with each other, and the first and third drive mechanisms (7a, 7c) change the inclination angle of the movable mold longer side, and when the second connecting shaft is rotated about its axis, the second and fourth drive mechanisms (7b, 7d) operate in conjunction with each other, and the second and fourth drive mechanisms (7b, 7d) change the inclination angle of the movable mold longer side. first and second drive mechanisms (7a, 7b) disposed in two places in the left-right direction on the upper side of one of the stationary mold longer side and the movable mold longer side and moving the movable mold longer side relative to the stationary mold longer side; third and fourth drive mechanisms (7c, 7d) disposed in two places in the left-right direction on the lower side of said one of the stationary mold longer side and the movable mold longer side and moving the movable mold longer side relative to the stationary mold longer side(la); characterized in that the mold further comprises: a first connecting shaft operatively connecting the first drive mechanism and the third drive mechanism disposed in the top-bottom direction; and a second connecting shaft operatively connecting the second drive mechanism and the fourth drive mechanism disposed in the top-bottom direction, wherein when the first connecting shaft is rotated about its axis, the first and third drive mechanisms (7a, 7c) operate in conjunction with each other, and the first and third drive mechanisms (7a, 7c) change the inclination angle of the movable mold longer side, and when the second connecting shaft is rotated about its axis, the second and fourth drive mechanisms (7b, 7d) operate in conjunction with each other, and the second and fourth drive mechanisms (7b, 7d) change the inclination angle of the movable mold longer side. a first connecting shaft operatively connecting the first drive mechanism and the third drive mechanism disposed in the top-bottom direction; and a second connecting shaft operatively connecting the second drive mechanism and the fourth drive mechanism disposed in the top-bottom direction, wherein when the first connecting shaft is rotated about its axis, the first and third drive mechanisms (7a, 7c) operate in conjunction with each other, and the first and third drive mechanisms (7a, 7c) change the inclination angle of the movable mold longer side, and when the second connecting shaft is rotated about its axis, the second and fourth drive mechanisms (7b, 7d) operate in conjunction with each other, and the second and fourth drive mechanisms (7b, 7d) change the inclination angle of the movable mold longer side.
