The utility model relates to a clutch thrusting steel disc which is an annular steep disc with meshing teeth, wherein the end face of one side of the thrusting steel disc is provided with two annular grooves concentric with the thrusting steel disc, one of the annular groove is cut to the outer edge of the thrusting steel disc so as to form a clamp spring limiting groove, and the other annular groove is cut to the inner edge of the thrusting steel disc; and in use, the clamp spring is arranged in the clamp spring limiting groove, thereby reducing the axial dimension of the clutch and simultaneously reducing weight.
