Problems solved by technology

Moreover, the torsion coil spring plays the role of overcoming the self-weight of the steering column and the steering wheel, etc., and exerts a force upwards. The elastic force is strong. The active force of the spring (6) becomes a burden on the operator
If the elastic force of the torsion coil spring (6) is reduced in order to reduce the burden on the operator, the torsion coil spring (6) will easily come out of the U-shaped notch groove (391) and so on.
[0007] In addition, it is necessary to assemble the periphery of the long grooves for tilting (33A, 33B) while maintaining the steering column (1) in a substantially horizontal state against the force of the torsion coil spring (6), and the operator must exert great effort. force
During the assembly operation, the operator must continue to apply force to overcome the force of the torsion coil spring (6), so the burden on the operator is huge

Embodiment Construction

[0020] Embodiments of the present invention will be described below based on the drawings. The main components of the present invention are as figure 1 As shown, it is composed of a fixed bracket A, a movable bracket 4, a spring component 7, a collar component 8 and the like. In addition, in the present invention, for the convenience of description, there are "front" and "rear" that represent the direction, but in the device of the present invention, the device located on one side of the traveling direction in the state of being mounted on the vehicle body is referred to as the front, The one on the side of the steering wheel is the rear. In addition, "width direction" means the left-right direction of a vehicle body. Words indicating directions such as "front", "rear", and "width direction" in the present invention are indicated in main drawings.

[0021] As shown in Fig. 2(A) and (B), the fixed bracket A has fixed side plate parts 1, 1 formed at appropriate intervals in t...

Abstract

A spring for assisting a tilt adjustment operation can be easily and rapidly attached to a fixed bracket and a movable bracket. Each of two flanges of a fixed bracket has a tilted flange plate and a locking piece. The locking piece has a guiding edge, a locking recess, an insertion recess, and a fixing hole. In a spring member, a first locking shaft portion is formed on the rear side of two coil portions, and a second locking shaft portion is formed rearward from the distal end of the first locking shaft portion. The first locking shaft portion is engaged with the locking recess, and the second locking shaft portion is engaged with the fixing hole. The distance between the first locking shaft portions of the spring member is less than the distance between the two guiding edges.

Description

technical field [0001] The present invention relates to a steering position adjustment device, which can easily and quickly assemble a spring for assisting tilt adjustment work on a fixed bracket and a movable bracket that supports a steering column and is installed on the aforementioned fixed bracket for tilting action superior. Background technique [0002] Conventionally, in the steering position adjusting device, the torsion coil spring for always biasing the steering column to the tilted upward side is straddled between the steering column and the upper vehicle body mounting bracket. In addition, the steering column is always biased toward the tilted upward side by the biasing force of the torsion coil spring. That is, by installing the torsion coil spring, it is possible to prevent the steering wheel side from tilting downward due to the weight of the steering column and steering wheel after the steering column is released from the restraint during tilt adjustment. D...
