Abstract
PURPOSE: To prevent sliding between rack teeth and pinion teeth and make operation accurate by forming a flexible rack with an elliptical horizontal cross section having a parallel part.
CONSTITUTION: Flexible rack 2 is formed by winding helically steel wire member 2a of nearly triangular cross section. Further, the horizontal cross section of this flexible rack is made nearly elliptical and it has nearly parallel part 2c. Moreover, the rack tooth valley distance d1 of this parallel part 2c is made shorter than other valley distance d2. As a result, even if pinion teeth 3a are flat teeth, they engage with rack teeth 2b accurately, and at the same time, rack 2 does not rotate so that the occurrence of sliding is prevented.
