PURPOSE: A threading equipment of the sewing machine needle using a wire loop with elastic deformation is provided to pass a thread through a needle correctly without hindering the stem of needle from working and lengthens lifetime of the wire loop. CONSTITUTION: The needle-threading equipment comprises the parts of: a diamond-shaped wireloop(41) capable of elastic deformation; a guide(20), a hollow body with a loop-guide part of which a hole(23) is on the end, which keeps the wire loop in and out and moves between the working position which the end hole gets close to a pinhole and the receding position which the hole gets far off a pinhole; a guide-running part(30) making the guide reciprocate to the working position and the receding position; a loop-running part set on the guide to make the wire loop pass the end hole and pinhole.
