Abstract:
[Problem] The objective of the present invention is to realize an outer column structure with which the rigidity of the outer column can be improved, and with which it is possible to suppress tilting thereof with respect to an inner column. A front side portion of an outer column 9a is configured from a substantially cylindrical column main body portion 15a which includes a pair of clamp portions 20a and which is fitted externally onto an inner column 8a, and a reinforcing bridge portion 16a provided integrally with a lower part of the column main body portion 15a. A front side linking portion 25a forming the reinforcing bridge portion 16a is provided with a front side inclined portion 45 which is inclined forward with increasing distance upward, and a rear side linking portion 26a is inclined backward with increasing distance upward. A reinforcing rib 44 is disposed in such a way as to extend in a front-rear direction on a lower surface of a bottom plate portion 24a forming the reinforcing bridge portion 16a, and to be continuous in a range from the lower surface of the bottom plate portion 24a to a front surface of the front side linking portion 25a.
