Claims

[Scope of utility model registration request]

An outer tube is fixed to a vehicle body member, an outer shaft is rotatably supported within the outer tube via a bearing, and a steering wheel is fitted into the outer shaft coaxially and removably in the axial direction. The wheel is attached to an inner shaft having a slit extending in the axial direction at its lower end, and an inner shaft which is in contact with the end of the inner shaft having the slit so as to be able to be displaced in the axial direction, and is disposed above the inner shaft. a locking member that expands the end of the inner shaft in the radial direction and fixes the inner shaft to the outer shaft; and a locking member that is coaxially and rotatably inserted into the inner shaft and has an operating lever at its upper end. A device comprising a fixed operating rod and a lock nut that is screwed onto the lower end of the operating rod and is displaced in the axial direction by rotation of the operating rod to drive the locking member, , a protrusion or flange extending radially outward that limits the maximum extension position of the inner shaft by abutting against a locking shoulder provided near the lower end of the outer shaft; , a steering shaft support comprising a protrusion extending radially outward to limit the minimum shortening position of the inner shaft by coming into contact with a locking shoulder provided near the upper end of the outer shaft; structure.
