IPC: B62D1/18
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To improve the durability of the switching mechanism of a steering position adjusting device which switches a tilting motion and a telescopic motion by the switching mechanism and to improve the rigidity of the device. SOLUTION: A switching mechanism 20 has a switching nut 46 screwing onto a screw shaft 40 and a moving pin 48 which is engaged with a teeth 46b to prevent the rotation of the switching nut 46. In a state in which the switching nut 46 is prevented from rotating, the switching mechanism 20 acts as a nut to prevent the drive force of the screw shaft 40 from being transmitted to the switching nut 46. In this case, only a force for preventing the switching nut 46 from being corotated is applied to the moving pin 48. In a state in which the switching nut 46 is not prevented from being rotated, the switching mechanism 20 acts as a bearing to transmit a drive force produced by the screw shaft 40 to the switching mechanism 20. In this case, the above mentioned drive force is not applied to the moving pin 46.

The cushioning members 22, 23 try to open forcedly a pair of disc 17, 18 with that centrifugal force. But, since the discs 17, 18 are formed in a rib-shape with the rigidity large enough to be resistable against the force to open forcedly, these discs are never opened. Further, even if the peripheral end of the disc 17 trys to move with the centrifugal force of the cushioning member 22, a projection 17e of the peripheral end abuts to a channel bottom part 14b of a lock up piston to hinder the movement of the peripheral end of the disc 17 to left more. The projection of the cushioning member 22 is thereby prevented more surely.
