Abstract
A motion guide device includes a ball nut attached onto a shaft and having helical grooves and a returning channel for forming an endless ball guiding passage and for receiving a number of ball bearing elements, two deflecting devices are engaged with the ball nut and each include a deflecting pathway communicative with the helical groove and the returning channel of the ball nut and each include a protrusion engaged with a recess of the ball nut for anchoring the deflecting devices to the ball nut, and the deflecting devices each include a connecting surface directed toward the helical groove of the ball nut for guiding the ball bearing elements to smoothly move between the helical groove of the ball nut and the deflecting pathways of the deflecting devices.
