Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tooth form molding device which can mold a tooth form surely at an inner and outer periphery of a material and also reduces a molding time thereof. SOLUTION: This is referred to a tooth form molding device to mold a tooth form at an inner peripheral surface and an outer peripheral surface of the material 6 provided with a die 1 having a tooth form at its inner periphery, a mandrel 2 having a tooth form at its outer periphery arranged at the inner periphery of the die 1, with a common axis center of the die 1 and punches 3 and 4 disposed between the die 1 and the mandrel 2 by moving in an axis direction along the tooth forms of the die 1 and the mandrel 2 to pressurize a cylindrical shape material 6. At least one of the outer periphery or inner periphery of the material 6 is a spline tooth to be molded by an extrusion molding.
