Claims

[Scope of utility model registration request]

A knuckle that supports the steering wheel is freely pivoted vertically via an arm member, and the nut is selectively pivoted to one of multiple mounting holes in the vehicle body in the vertical direction, so that it is attached to the vehicle body. In a vehicle height adjustment device for a steered wheel in which the steered wheel is vertically adjustable and the vehicle body is steered via a tie rod and a knuckle arm, the pivot point between the tie rod and the knuckle arm is independent of the vertical position of the knuckle. , a line parallel to the arm member passing through the central mounting hole of the plurality of mounting holes and passing through the base end pivot point of the arm member so that the tie rod has a constant positional relationship in the longitudinal direction. Other than the center mounting hole, from on an arc drawn with a radius equal to the length of the arm member, centered on the virtual swing center point that is the intersection of a line parallel to the line connecting the tip pivot point of the member and the center mounting hole. A vehicle height adjustment device for a steering wheel, characterized in that the mounting hole of the steering wheel is shifted to the side.
