PURPOSE: A forged block frog-shaped frog is provided to simplify the structure of a carrier connected to a controller and to reduce manufacturing costs. CONSTITUTION: A forged block frog-shaped frog(22) comprises a carrier(30). The carrier is connected to the frog and can be released. The carrier is extended from the bottom surface(28) and side planks(26,27) of the frog and can be connected to a controller. Recesses are formed in the side planks and are forged. Plate parts(36) of the carrier are inserted into the recesses and are connected using fixing units(48,50,52,54).
