PROBLEM TO BE SOLVED: To provide a vehicle steering device capable of reducing non-linearity between a steering torque of a driver and vehicle behavior on quick turn of a wheel.SOLUTION: A coil wire 17 is subjected to insert formation for a dust boot 16 with which a ball stud 13 is covered, and upper and lower end parts of the dust boot 16 are fixed to a tip part 10a of a knuckle arm and a ball socket 12 of a tie-rod end 8. When a driver performs quick turn of a steering wheel to transmit a steering torque from the tie-rod end 8 to the knuckle arm via the dust boot 16 and steers a front wheel, a torsion is produced between the tie-rod end 8 and the knuckle arm. However, such a torsional load is absorbed by spring-deformation of the dust boot 16 to which the coil wire 17 is inserted and, therefore, the non-linearity is reduced. |
