摘要： A hydraulic pressure control valve includes a cylindrical valve body and a valve spool coaxially fitted therein, each having oil grooves and lands alternately provided on and along the respective peripheral inside and outside surfaces, the opposing oil grooves and lands having throttles therebetween whose throttling extent, are changeable in accordance with a relative angular displacement between the valve body and the valve spool such that the flow of a working oil is concentrated in wider throttles. Thus noise due to cavitation is reduced.

摘要： A shock absorbing type steering device decreases variations in press fitting loads corresponding to a friction force between two columns. A shock can be appropriately absorbed by relative movements of the two columns in an axial direction. At least one of a first column and a second column press fitted into an opening at one end of the first column is formed with swaged parts on a peripheral wall thereof at a plurality of positions having intervals in a circumferential direction of the column, respectively at a plurality of positions having intervals in an axial direction of the column. Positions of tip ends of the swaged parts are different between a group of swaged parts near the opening at the end of the first column and other groups remote from the opening.

摘要： A tilt steering apparatus comprises a lock lever rotatable around the axis of a supporting shaft. When a lock lever is rotated around the axis of the supporting shaft, a cam surface is rotated relative to a cam follower. As a result, the cam surface presses the cam follower against side plates of a fixed bracket, thereby achieving tilt locking. The cam surface has a plurality of slopes corresponding to a rotation stroke position of the lock lever. The operating torque of the lock lever at the time of a locking operation is reduced without increasing the range of the operating angle of the lock lever.

摘要： With the steering apparatus, a tilt can be adjusted by sliding a column bracket, which is fastened to a column housing supporting a steering shaft so as to be rotatable, along tilting apertures provided at side walls of a tilting bracket. A contact projection which is projected toward a stopper from a substantially center portion of the column bracket for limiting a tilt angle crashes into the stopper with a slide of the column bracket caused by a secondary crash and pushes the stopper into guiding apertures arranged in an extension to the tilting apertures. The steering apparatus can realize absorption of energy of a secondary crash by increasing a tilt angle always under a proper condition, while high accuracy is unnecessary in shaping related parts.

摘要： A lower bracket for mounting a steering column to a vehicle body is formed as a single element that is fixed to the vehicle body by inserting a bolt with a collar therethrough. Upon application of an impact load, the lower bracket forces the bolt and collar into a path of a smaller width than the collar thereby plastically deforming an edge portion of the path for absorption of the impact energy.
