To provide a die device equipped with a filling auxiliary member in a molding apparatus for an annular rubber member capable of effectively preventing not only the adhesion failure of an annular reference member and an annular member but also product defectiveness.
The filling auxilary member 14 for changing the flow of a rubbery elastic material Ga toward a molding plate 11 is attached to the side surface 13 on the molding side of a die body 12a through a clamping member 15 such as a bolt or the like. The filling auxiliary member 14 is a protruded member for pushing the rubbery elastic material Ga in a region where the filling with a material is insufficient at the time of molding of the annular member Wa and attached so as to inclined toward the lower sides of the molding plate 11 and the annular reference member Q.
