Claims

[Scope of utility model registration request]

In a telescopic steering shaft mechanism in which a tube column, a hollow outer shaft, a hollow inner shaft for attaching a steering wheel, and an operating rod are sequentially inserted into the former, the inner diameter portion of the outer shaft located below the lower end of the inner shaft is One or more pairs of restraint assembly members, each consisting of a cylindrical elastic skirt and a wedge body, are disposed inside on the axis of the outer shaft, and the skirt portion has a plurality of slits opening at one end, and the other end is connected to the inner shaft. The wedge body is connected to the shaft system or the operating rod system and is provided so as to be immovable relative to the outer shaft, while the wedge body has a conical surface that can be press-fitted to the inner periphery of the end of the skirt on the slit opening side and that can be press-fitted into the skirt. When the wedge body or skirt is moved in the axial direction by the operation of the operating rod, the skirt of the assembled member and the wedge body are pressed into contact with each other or separated, and the skirt accordingly Enlargement of the outer circumference on one end brings the skirt into even pressure contact with the inner diameter wall of the outer shaft, or reduction of the outer circumference on the same end leads to the separation of the skirt from the inner diameter wall of the outer shaft, thereby making it possible to restrain or release the inner shaft and outer shaft. A restraining device for a telescopic steering shaft, characterized in that it is configured as follows.
