摘要： PROBLEM TO BE SOLVED: To provide an end fixing structure for a flexible shaft whereby an end of the flexible shaft can be fixed without displacing the shaft center, and generation of torque fluctuation is prevented. SOLUTION: In a flexible shaft 10, in the periphery of a core wire 12, a helical plate 14 is arranged, and in its periphery, right/left windings 22B, 22A are wound. The end of the right/left winding 22B, 22A is tightened by a collet chuck 30 comprising an outer ring 34, inner ring 36 and a bolt 46, to be fixed to a housing 32. Since the end of the right/left winding 22B, 22A is simply tightened to be fixed to the housing 32, in an end fixing part and the other main unit part of the flexible shaft 10, displacement of the shaft center is prevented from being generated. Consequently, when the flexible shaft 10 is rotated, torque fluctuation is prevented from being generated.

摘要： PROBLEM TO BE SOLVED: To change the steering force according to the vehicle running condition such as the car speed and the steering angle, as well as to regulate the steering force according to the individual demands, and to make the steering device in a simple structure and at a low cost. SOLUTION: In this steering device, a steering shaft 10 which consists of a core line 12, an orthogonal winding 20, a left direction winding 20A, and a right direction winding 20B is provided. The tensions of the left direction winding 20A and the right direction winding 20B can be changed by the rotation of a set bolt 14 (a motor 18). At the curve part of the steering shaft 10, a moving resistance is generated in the left direction winding 20A and the right direction winding 20B. Since the moving resistance is responsive to the tensions of the left direction winding 20A and the right direction winding 20B, the steering force can be increased and decreased adequately, by controlling the rotation of the motor 18 according to the individual demands or the vehicle running condition such as the car speed and the steering angle.

摘要： PROBLEM TO BE SOLVED: To effectively use an electric motor to a steering assist mechanism, a telescopic mechanism and a tilt mechanism. SOLUTION: The electric motor 21 rotates a transmission rod 34. When the transmission rod 34 is in a first position, the rotation is transmitted to a steering shaft 16 via gears 41, 22 to assist steering operation of a steering wheel 11. When the transmission rod 34 is in a second position, the rotation is transmitted to a screw rod 23 via gears 42, 23a to displace a telescopic tube 13 in the axial direction via a nut 24 to adjust a position of the steering wheel 11. When the transmission rod 34 is in a third position, the rotation is transmitted to a screw rod 26 via gears 43, 26a to tilt an upper tube 14 via a nut 27 and a link 28 to adjust a position of the steering wheel 11.

摘要： PROBLEM TO BE SOLVED: To provide a flexible shaft which has large torsional rigidity and can transmit large torque without increasing the number of turns of wire. SOLUTION: In a flexible shaft 10, a spiral plate 14 is arranged spirally around a core wire 12. A left-hand wound wire 22A and a right-hand wound wire 22B are spirally wound around the spiral plate 14 such that they are crossing each other. When a large torsional force is applied to the flexible shaft 10, a fastening force in the radial direction of the left-hand wound wire 22A and the right-hand wound wire 22B is increased but is received by the spiral plate 14 to keep the radii of wind of the left-hand wound wire 22A and the right-hand wound wire 22B, whereby torque can be transferred reliably. The number of turns of the left-hand wound wire 22A and that of the right-hand wound wire 22B are not increased and hence the outer diameter of the flexible shaft 10 is not increased.

摘要： PROBLEM TO BE SOLVED: To provide a steering device for a vehicle not only capable of changing a steering gear ratio in accordance with a steering angle of a steering wheel, but capable of optionally setting an steering angle characteristic suitable for the vehicle and extending freedom of design. SOLUTION: A steering device 10 for a vehicle is furnished with a rack bar 22 and a disc 30 to axially move by steering of a steering wheel 24, and an eccentric pin 36 of the disc 30 is put in a slit 46 of an oscillating link 42. When the rack bar 22 axially moves, the disc 30 is rotated while axially moving, the eccentric pin 36 oscillates the oscillating link 42 and a turning rod 12 is driven. As the eccentric pin 36 is rotated while axially moving, actual moving quantity increases, a pressurizing position of the oscillating link 42 is changed, and a lever ratio is changed. Consequently, a steering gear ratio is changed in accordance with a steering angle of the steering wheel 24.
