The invention discloses a platinum-rhodium alloy bushing plate with a U-shaped groove, and belongs to the technical field of flexible glass forming equipment. The platinum-rhodium alloy bushing platecomprises a groove body, and a slit for allowing molten glass to pass through is formed in a bottom plate of the groove body; the length direction of the slit is the same as that of the groove body; the key point comprises that the slit is divided into a first width gradual change slit, a middle equal-width slit and a second width gradual change slit which are sequentially connected from one end to the other end in the length direction, and the widths of the first width gradual change slit and the second width gradual change slit are gradually reduced from one end close to the middle equal-width slit to the other end. The slit with the wide middle and two narrow ends can effectively reduce the edge thickness of a glass tape, so that the effective width ratio of the glass is increased, andthe appearance of a glass plate is smoother.
