PROBLEM TO BE SOLVED: To finish a flow edge part at the end edge of a tread rubber for regeneration on a various kinds of base tires in the same manner and thereby obtain a retread tire with a good appearance by constituting a split mold for the retread tire in such a manner that the degree of pressing the flow edge part at the end edge of the tread rubber for regeneration to the base tire side can be regulated. SOLUTION: The split mold 11 for a retread tire comprises a pair of upper/ lower side molds 2, 2, a sector 3 with a segment 5 and an actuator 4. A dovetail-shaped recessed groove 6, into which the actuator 4 is fitted is formed vertically in the sector 3. In addition, the upper side mold 2 is provided in such a way that it is freely brought into contact with and separated from the lower side mold 2. On the outer peripheral face of each of the side molds 2, 2, a flow stop part 12 is attached and a projecting piece part 16 is formed outwardly in the diametral direction and a regulator 17 such as a bolt is screwed into the part 16, in the flow stop part 12. The flow stop part 12 is moved by rotating the regulator 17, considering the finish condition of a flow edge part at the end edge of a tread rubber.
