Abstract:
1. A steering device, comprising: a bracket for installing on a vehicle body attachable to the vehicle body; a column the tilt position of which is adjustably supported by the bracket for installing on the vehicle body and which turnably supports a steering shaft where a steering wheel is installed; a clamping rod inserted into a long groove for tilt adjustment formed on each side plate and the column so as to clamp the column on a pair of right and left side plates of the bracket for installing on the vehicle body in a desired tilt position and clamp a tilt; a fixed cam which is supported by one end of the clamping rod and which presses an inside face of one side plate of the bracket for installing on the vehicle body on the column; a movable cam turnably supported together with an operating lever by one end of the clamping rod opposite to the fixed cam; a cam face which is provided to each opposite surface of the fixed cam and the movable cam and which relatively axially presses the movable cam opposite to the fixed cam; a detent formed on the fixed cam so as to disable the relative turning of the fixed cam for the movable cam, which is fitted into the long groove for tilt adjustment and which can be slid along the long groove for tilt adjustment when the tilt position of the column is adjusted; a fixed tilt lock gear attached to an outside face of one side plate of the bracket for installing on the vehicle body; a movable tilt lock gear which is turned in synchronization with the turning of the operating lever and which can be engaged with the taxed tilt lock gear; a fitting protrusion turned in synchronization with the turning of the operating lever and formed at an end of an elastically deformed part; a sliding surface which is provided to the bracket for installing on the vehicle body, to which the fitting protrusion is slidably touched and which is ordinarily touchable; a stepped part which is formed on the sliding surface across length for tilt adjustment, to which the fitting protrusion is fitted when the column is clamped and the tilt is clamped and which blocks the turning in a direction in which clamping is released of the operating lever; a groove which is formed on the sliding surface across length for tilt adjustment, into which the fitting protrusion is fitted when the clamping of the column is released and unclamping is performed and which blocks the turning of the operating lever; and an inclined face which is formed between the stepped part and the groove of the sliding surface across length for tilt adjustment, on which the fitting protrusion is slid when the operating lever is turned and which ordinarily presses the operating lever in the direction in which the clamping is released.
