PROBLEM TO BE SOLVED: To provide a molding method for a roller connection body for preventing unreasonable force from being applied to a spacer having undercut when releasing from a mold. SOLUTION: This molding method for the roller connection body comprises a process for preparing a fixed mold 21 having a fixed mold side protruding part 21a whose shape is matched with either 12a of a pair of curved face recessed parts in which adjacent spacers 12 face mutually and a movable mold 22 having a movable mold side protruding part 22a whose shape is matched with the other 12a of the curved face recessed parts, a process for tightening the fixed mold 21 and the movable mold 22 to form a cavity corresponding to shapes of the spacer 12 and a flexible band 13, a process for injecting resin into the cavity, and a process for opening the mold to retract the movable mold 22 obliquely for a matching face 24 of the fixed mold 21 and the movable mold 22 so as to avoid the spacer 12 in which the movable mold side protruding part 22a of the movable mold 22 is formed by resin.
