PURPOSE:To easily adjust the position of a handle further to effectively relax the collision against a driver, by rotatably supporting upper and bottom side shafts by upper and bottom side columns while interposing a ball by press fitting to an overlapped part of the both columns and providing a ball ride-up step in the moving end in the axial direction of said overlapped part. CONSTITUTION:An upper side column 3 is released from its clamping to a car body, and if a position of the upper side column is adjusted, a position in the axial direction of a handle 25 can be adjusted. Here a ball 16 is interposed by press fitting in a part where both upper and bottom columns 3, 15 are overlapped, and friction of said ball 16 prevents the both columns 3, 15 from telescopically moving without any cause. As a result, fine adjustment of the handle 25 can be easily performed with the original fixed position serving as the reference. While collision is effectively relaxed because energy in the time of collision is absorbed also by the initial resistance of friction of the ball 16 prior to its ride-up movement onto the final ends 27a, 28a of grooves 27, 28. |
