A wire drawing device is provided to adjust each position of axial or diameter directions of roller dies easily by processing a corresponding wire via passing through a molding hole formed by a pair of roller dies. A wire drawing device comprises a frame body(10), a pair of roller dies(1A, 1B), support axes(20, 30), a first bearing(40), a second bearing(50), a position adjusting device for axial direction of the first and second roller dies, and a position adjusting device for diameter direction of the first and second roller dies. The pair of roller dies processes wire by passing through a molding hole formed by the roller dies to have a molding groove at an outer periphery. The support axes have the first and second eccentric axes including a cooling medium passage and the eccentric axes deflected for the axial centerlines one side and the other side. The first bearing is fixed on the eccentric axis of the support axes having the first eccentric axis to mount one side of the pair of roller dies and to support one side of roller dies rotatably. The second bearing is fastened on the eccentric axis of the support axes having the second eccentric axis to place the other side of roller dies and to hold the other side of roller dies rotatably. The position adjusting device for axial direction of the first and second roller dies maintains the support axes having the first and second eccentric axes to be movable rotatably to each axial direction on the frame body. The position adjusting device for diameter direction of the first and second roller dies maintains the support axes having the first and second eccentric axes to be movable rotatably around the axial lines of one side and the other side on the frame body.
