PURPOSE: A flexible fish plate for casting is provided to improve the flexibility and elasticity of the fish plate by attaching wiring rings with uncut trapping rubbers of which grain directions are maintained at 45deg. in the zig-zag pattern, thereby improving the product quality and lifespan. CONSTITUTION: A flexible fish plate for casting includes an inner rubber(40), an outer rubber(50), a first trapping rubber(30-1), a second trapping rubber(30-2), a third trapping rubber(30-3), and a fourth trapping rubber(30-4), wherein the first to fourth trapping rubbers are attached between the inner and outer rubbers to have opposite grain direction with about 45deg. The first and second trapping rubbers are uniformly attached by not cutting end parts and winding the end parts with wiring rings(10-1,10-2) not to be wrinkled or overlapped on each trapping surface. Each wiring ring is surrounded by a base ring(15) and a middle rubber, the middle rubber being formed by attaching two rubbers(20-1,20-2) respectively having a grain of 45deg.
