PROBLEM TO BE SOLVED: To achieve a structure capable of increasing the number of friction surfaces for securing holding force of an outer column 13a to a support bracket 12 by providing additionally one friction plate.SOLUTION: One telescopic rocking friction plate 25 is installed while being sandwiched between an inner surface of a support plate part 20a forming a support bracket 12a and a side surface of a displacement bracket 18a fixed to an outer column 13a. When adjusting a longitudinal position of a steering wheel, while displacing an adjustment rod 22a along slots 19a for telescopic adjustment and guide pins 33 projected on the side surface of the outer column 13a along guide slots 32, respectively, the telescopic rocking friction plate 25 is rocked around the adjustment rod 22a. As a result of employing such a construction, abutment parts between both side surfaces of the rocking friction plate 25 for telescopic and mate surfaces work as friction surfaces and therefore a problem described above can be solved.SELECTED DRAWING: Figure 2 |
