A steering gear apparatus of the rack-and-pinion type including a pinion formed with helical teeth and a rack member formed with helical teeth which are brought into meshing engagement with the helical teeth of the pinion in such a manner that a steering effort is applied to the meshed portion of the helical teeth of the pinion and rack member at a predetermined angle relative to an axis line of the rack member, the rack member being resiliently biased toward the pinion, wherein the helical teeth of the pinion or the rack member each are formed with a tip portion to be brought into engagement with each root of the helical teeth of the rack member or the pinion.

An anti-lock brake system for a wheel wherein a fluid pressure is applied to a wheel cylinder, through a solenoid-operated valve device and a flow control device. Upon detection of locking of the wheel, the valve device is brought into an anti-lock state in which the valve device is alternately placed in its pressure-increase and pressure-decrease positions. The flow control device is normally placed in a first mode for a sufficient flow of the fluid into the wheel cylinder, and is operated in a second mode with the valve device placed in the anti-lock state. In the second mode, the flow control device decreases the rate of fluid flow to the wheel cylinder, with an increase in a difference between the power source pressure and the wheel cylinder pressure. An assisting device is provided for enabling the flow control device to adequaely effect the first mode of operation for at least a period between commencement of brake application and commencement of anti-lock operation of the valve device. The assisting device further assists the flow control device to adequately effect the second mode of operation at least while the valve device is in the pressure-increase position during the anti-lock operation of the valve decive.

The present invention relates to a method for fixing an annular element onto a shaft. The shaft may be a camshaft and the annular element may be a cam piece or a journal piece used in an automobile. The annular element is fixed onto the shaft by: engaging an axially extending projection of the element with an axially extending groove of the shaft so as to prevent a relative rotating motion; deforming an outer wall of the shaft adjacent to said groove at two positions near the terminating ends of the projection so that the outer wall protrudes into the groove, thereby fixing the element onto the shaft.
