PROBLEM TO BE SOLVED: To provide a pasting-up method of a tire constituent member by means of a tire molding drum for improving the press bonding workability of a tread member and a casing member, preventing the air sump between the members or the pasted-up part of the terminal parts of the members from being opened and achieving enhancement of manufacturing precision and marked reduction of manufacturing trouble. SOLUTION: A belt member 1 and a cap tread 2 are smoothly formed on a drum main body 11 to form a tread member 3. When the tread member 3 is bonded to casing member 6 after molding, the divided plates 12 of both end parts of the drum main body 11 are altered into the curved shape corresponding to the bonding shape of the casing member 6 and the tread member 3 as shown in Fig. 9. The alteration of the surface shapes of the respective plates 12 is performed by expanding and contracting an expansion and contraction means 13 and the belt member 1 and the terminal part of the cap tread 2 are bonded under pressure by a press bonding means such as a press bonding roller or the like not shown in Fig. on the altered drum main body 11 as shown by Fig. 10 to form a habit corresponding to the bonding shape with the casing member 6.
