Summary:A yarn draw off tube for an open-end spinning unit which improves the twist transmission to a fiber ribbon in a spinning rotor. The yarn draw off tube is provided with a yarn inlet on the top wall thereof and a yarn outlet on the lower side wall thereof, and the yarn inlet is eccentric from the center in a direction opposite to the yarn outlet. In the spinning operation, a twist imparted to a yarn drawn off from the spinning rotor can smoothly be transmitted to the root portion thereof. Thereby, yarn breakage is restrained and a yarn of good appearance and strength can be obtained.
