To change a steering angle ratio according to a steering angle of a steering by only a mechanical constitution without using electric control equipment such as a motor in a variable steering angle ratio unit provided with an input shaft connected to the steering side and an output shaft connected to a wheel side.
This variable steering angle ratio steering device for a vehicle is provided with a linear moving member 20 connected to the input shaft 3 via a ball screw mechanism 19, a driving bevel gear 23 connected to the output shaft 4 to be interlocked via a connecting bevel gear 21, and a lever member 24 for connecting the linear moving member 20 and the driving bevel gear 23 with each other to be interlocked so that linear moving amount X of the linear moving member 20 may be a sine function of a rotary angle w of the driving bevel gear 23.
