<p>PROBLEM TO BE SOLVED: To provide a steering device capable of suppressing allophone generation.SOLUTION: A steering angle ratio variable mechanism comprises: a cam member 31 having a cam groove 35; an eccentric pin 32 disposed so as to move in the cam groove 35 freely and having a rotatable top member 42; and a coil spring 33 formed by bending a metal wire into a spiral shape. The cam member 31 is disposed so as to rotate with an input shaft in an integrated state, the eccentric pin 32 is disposed so as to rotate with an output shaft in an integrated state at a position where has significant eccentricity than an eccentricity amount of shaft lines of the input shaft and the output shaft. The top member 42 has a cylindrical winding part 43, and flange-shaped stopper parts 44 extending toward outside of a radial direction from both ends of a shaft direction of the winding part 43. In addition the coil spring 33 is wound around an outer periphery of the winding part 43 of the top member 42 so that a ring-shaped part 51 forming the spiral shape is compressed between the cam groove 35 and the top member 42.</p> |
