Abstract

PURPOSE: To get a variable gear ratio, by converting part of the relative revolution between an input shaft having spiral external tooth and a sleeve element having spiral internal tooth to be fitted to the external tooth into the axial movement of the sleeve element against the input shaft.
CONSTITUTION: When the direction of a front wheel is altered by revolving an input shaft 16 through revolution of a steering wheel, a sleeve element 11 produces a relative displacement of revolution against the input shaft 16 due to the difference between an internal tooth 14 and external tooth 15. Because of this displacement the point of engagement between a pin 23 of the input shaft 16 and a cam groove 21 of a cam sleeve element 20 is shifted, and the pin 23 is engaged with an inclined portion 21b or 21c of the groove 21, accordingly the sleeve element 11 is axially shifted against the input shaft 16. This makes the internal tooth 14 and the external tooth 15 engage with each other, which leads to produce a delay in the turning angle of the sleeve element 11 by that amount, the revolution being delayed from a gear ratio determined with regard to the turning angle of the input shaft 16.
