An edge dam of a twin roll type strip caster is provided as a refractory material having a sealing member for sealing both end surfaces of a pair of casting rolls, and is pressed and raised according to wear of the sealing member. To uniformly maintain a contact area of the sealing member and the casting roll in a process in which the edge dam is moved while the edge dam is pressed and raised, both sides and a lower part of the sealing member are formed as an inclined surface inclined inwardly of the sealing member. An angle of inclination of the inclined surface is increased in a direction in which the sealing member is raised, and the angle of inclination &#x3b8; of the inclined surface is obtained by a relationship between a moving distance l due to raising of the edge dam and a wear depth d.
