However, as each part becomes familiar with the vehicle while driving,
There was a problem in which play occurred due to wear and the steering wheel felt less responsive when in neutral. In order to solve this problem, it was necessary to tighten the adjustment bolt every time play occurred, which was troublesome.

In the drawings, a main shaft 1 is pivotally supported within a casing 2, has a threaded groove 3 formed on its circumferential surface, has a large number of balls 4 mounted in the threaded groove 3, and is connected to a steering wheel (not shown). The ball nut 5 is screwed onto the main shaft 1 via the ball 4, and has teeth 6 at its right end. The cross shaft 11 is pivotally supported by the casing 2 and has teeth 7 that mesh with the teeth 6 described above. Spring 8
is a retainer 9 whose lower end has a concave shape as shown in the figure.
The ball nut 5 is brought into contact with a portion of the ball nut 5 that is closer to the cross shaft than the main shaft center axis, and its upper end is brought into contact with a cap 10 screwed into the casing 2, and the ball nut 5 is rotated clockwise about the center axis. It is energizing. Note that the teeth 7 are formed to be inclined with respect to the center line of the cross shaft 11.

Therefore, the teeth 6 and 7 fit together, and even if they wear out, the ball nut 5 is always urged to rotate clockwise by the spring 8, so that the teeth 6 and 7 fit together.
It is always pressed and there is no play. Moreover, even if wear occurs between the ball nut 5 and the main shaft 1, since the ball nut 5 is pressed against the main shaft 1, no play will occur.
