Abstract: An electric power steering apparatus includes a steering shaft having its upper end to which a steering wheel is fitted, a steering column rotatably supporting the steering shaft, tilting about a pivot as a fulcrum and moving telescopically together the steering shaft in axis-directions, an electric assist motor unit attached to the steering column and serving for a steering assist of the steering wheel, and a tilt/telescopic adjustment means for fixing the steering column in a predetermined angular position and fixing the steering column in a predetermined axis-directional position, wherein the pivot is disposed between the electric motor unit and the tilt/telescopic adjustment means.

Abstract: A universal joint has a shaft including a pair of outer side planes at its front end a yoke connecting the pair of outer side planes of the shaft, the yoke including a base end portion having an opening portion and a pair of restraining plate portions having restraining faces opposing to the respective outer side planes and a through hole or a screw hole and a connecting portion connecting the pair of restraining plate portions and a restraining bolt screwing a male screw portion formed at a front end portion of the base end portion to fasten the outer side planes of the shaft, wherein the yoke is made of a material having a tensile strength 310 N/mm2 or more.

Abstract: In an impact absorbing type steering column apparatus for an automotive vehicle in which an upper column is fitted to a lower column fixed to a car body so as to absorb an impact energy upon a secondary collision while moving the upper column along the lower column towards a front side of the automotive vehicle, a low-friction material treatment is effected on one or both of slide surfaces of fitting portions of the two columns, or a sleeve subjected to the low-friction material treatment is interposed between the fitting portions thereof.

Abstract: The activating efficiency of water in the magnetic treating apparatus is enhanced by the electric conductors 4 located in the magnetic field-generating region 5 or by utilizing a magnetic circuit having the dipole magnetic ring structure 10.

Abstract: A universal joint comprises a pair of yokes each formed by bending a metal plate, a single piece of cross shaft for connecting the pair of yokes to each other so as to be capable of oscillating and displacing, and a bolt for fixing each of the yokes to an end portion of a shaft. The yoke includes a joint cylindrical portion provided at a proximal end portion thereof and having a discontinuous portion at one place in a circumferential direction, first and second flange portions provided in parallel to each other at a part of the joint cylindrical portion with the discontinuous portion sandwiched in therebetween, a through-hole formed in the first flange portion thereof in such a direction as to bear a torsion positional relationship with the joint cylindrical portion, a screw hole formed in a fixing portion of the second flange portion and disposed concentrically to the through-hole.

Abstract: A tilt type steering apparatus makes the amount of downward protrusion of the front end position of a rear steering column small to prevent interference with knees and prevents the rear steering column from becoming longer than necessary. A first lateral shaft connects a front steering column to a rear steering column. A second lateral shaft, provided under the rear steering column, is rockable about the first lateral shaft. An engagement member is pivotally supported by the second lateral shaft, and displacement side meshing teeth are formed on an upper edge of a front end portion of the engagement member. Fixed side meshing teeth are formed on a lower surface of a restraining member fixed to a lower surface of a support bracket. The displacement and fixed side meshing teeth are engaged and disengaged with each other by a rocking movement of a tilt lever.

Abstract: A lash adjuster has a plunger assembly comprising a plunger and a plunger cap. A separator is provided in the plunger cap to prevent the air mixed in the introduced oil from flowing into a reservoir chamber. The plunger cap further has a valve device in addition to the separator for preventing external air from being drawn into the lash adjuster.

Abstract: A process for manufacturing a high tensile steel wire, characterized by comprising the steps of pre-cooling a hot-rolled steel rod to a temperature between 750.degree.-900.degree. C. by means of a cooling apparatus provided between a group of intermediate rolling mills and a group of finishing rolling mills in a hot rolling line for steel rod, finishing rolling the thus pre-cooled steel rod, quenching the hot rolled steel rod to a temperature of 700.degree. C. or lower to provide a supercooled austenite phase, then finishing-cooling the thus quenched rod to provide martensite, and drawing the resulting steel rod with roller dies without descaling is disclosed.
