<P>PROBLEM TO BE SOLVED: To provide a steering device which can control the axial movement of a piece member and can simplify a supporting structure of the piece member by an eccentric pin. <P>SOLUTION: A steering angle ratio variable mechanism 7 contains a guide mechanism 51 which is provided in a cam groove 22 together with a piece member 23 to guide the movement of the piece member 23. The guide mechanism 51 comprises a guide groove 53 which extends in an extending direction and is opened to the piece member 23 side in a width direction, a curved plate spring 52 containing spring parts 61, 63 forcing the guide groove 53 to be biased to the piece member 23 side and a rolling element 73 provided between the guide groove 53 and an opposed groove 66 formed in the piece member 23 so as to be movable in an extending direction. The piece member 23 is guided to move in the extending direction of the piece member 23 with the axial movement thereof regulated by biasing the rolling element 73 to the spring parts 61, 63 to be engaged with the guide groove 53 and opposed groove 66. <P>COPYRIGHT: (C)2012,JPO&INPIT |
