Problems solved by technology

In addition, since the protrusion 24 is formed in an arc shape, it is difficult to control the size, and the biting amount of the locking part 15 is likely to be uneven.
On the other hand, if the biting amount of the locking part 15 is not uniform, the pressing load and pulling load become unstable.

Embodiment Construction

[0037] Embodiments of the present invention will be described below based on the drawings. First, the present invention relates to the operating lever portion of the tilt and telescoping adjustment mechanism of the steering device. In the present invention, the structure of the steering device is mainly composed of a lever body A, an operating knob B, a fixed bracket 6, a movable bracket 7, and a steering column 100 as shown in FIG. 2(C). The tilting long holes 61 and 61 of the fixing bracket 6 are formed in an arc shape substantially in the vertical direction, and serve as portions through which tilting bolts 9 described later penetrate.

[0038] A steering column 100 is fixed to an upper end portion of the movable bracket 7 . The steering column 100 and the movable bracket 7 are fixed by methods such as welding. A rotatable steering shaft 200 is attached to the steering column 100 , and a steering wheel 300 is attached to the tip of the steering shaft 200 .

Abstract

An operation lever includes a lever main body A having a tapered insertion portion (1) which has locking portions (11) and in which the size in the up-down direction decreases gradually and an operation knob B having a tapered insertion hole (3)in which a size in the up-down direction decreases gradually from an opening (3a) toward a deep end wall surface (3b). The insertion hole (3)includes tapered reference surface (31)facing each other in the up-down direction. Grooves (33)are formed from the opening and along the deep end wall surface (3b) so as to protrude outward from the respective tapered reference surfaces (31) and the inner side surfaces in the insertion hole of the operation knob. The insertion portion (1) is inserted into the insertion hole (3)and the locking portions (11) bite in outward through the respective tapered reference surfaces(31).

Description

technical field [0001] The present invention relates to an operating rod in a steering device. This operating rod constitutes a steering device with tilt and telescopic functions. When assembling this operating rod, a knob can be installed on the rod simply and quickly. And can achieve extremely firm installation. Background technique [0002] On the steering device with tilt and telescopic function, in order to adjust the tilt and telescopic, there is an operating lever for locking and unlocking. Such an operating lever is generally composed of a metal lever and a synthetic resin operating knob. [0003] Patent Document 1 (Japanese Patent Application Laid-Open No. 2000-66750) discloses a configuration of a joystick device for tilt operation of tilt steering. In summary, the operation lever device 1 is composed of a lever body 10 and an operation knob 20, and the lever body 10 is formed by punching a flat metal material with a punch. At the front end portion of the lever ...
