Abstract
To provide a steering column system which has superior operating feeling and operating properties which can suppress an operational failure, an engaging arm is displaced relative to a cam member by an annular member that is deformed elastically. Distal ends of gear teeth are made to shift from each other, making it possible not only to enhance the feeling of the operation lever, but also to facilitate meshing of the gear teeth.
Claims7
A steering column system in which a column is fixed relative to a body by a gear meshing function by a steering position adjusting operation lever, wherein the operation lever comprises:
- an engaging arm which includes gear teeth which provide the gear meshing function and
- an adjusting arm on which a position adjusting bolt is assembled and which performs a position adjusting operation, and
- wherein at least the engaging arm is supported in such a manner as to be displaced within a predetermined range relative to the column by passing the position adjusting bolt through an oscillation center hole provided in the engaging arm;
- wherein the engaging arm and the adjusting arm are permitted to perform a predetermined relative movement to each other;
- and
- wherein an elastic element is disposed between a projection which is provided on one of the engaging arm and the adjusting arm and a receiving portion which is provided on the other.
