PROBLEM TO BE SOLVED: To enable to manufacture a runner with a plurality of types of lugs which can reduce the rolling of a vehicle body by arranging the rugs in a good balance. SOLUTION: The runner die 2 for molding with the lug comprises a first die 21 having a recess 24 for forming a first long lug part and a first short lug part forming recess 25 formed at a first pitch P1, and a second die 22 having a recess 27 for forming a second long lug part and a recess 28 for forming a second short lug part formed at a second pitch P2. In the runner die 2 for molding with the lug, the first pitch P1 of the first die 21 is equalized to the second pitch P2 of the second die 22 so that, when the first die 21 and the second die 22 are opposed to one another and connected, they can be changed in the state to a first state A and a second state B.
