Abstract
A ball return tube for connecting openings of a ball nut to circulate balls comprises tube end portions for being coupled to the openings of the ball nut, and a tube body connecting the tube end portions so that the balls can pass through the tube body. The ball return tube is constructed in first and second tube portions fixedly joined together by structures included in a first projection protruding from a first surface of the tube body. The ball return tube further comprises one or more of a second projection protruding from a second surface of the tube body in a direction toward the ball nut, a third projection protruding from a lateral side surface of the tube body, and a fourth projection protruding from the tube open end portions so that the projections can be coupled to corresponding recesses of the ball nut.
