摘要： An electric power steering apparatus comprises a transmission mechanism for transmitting driving force of a steering assisting electric motor to a steering mechanism. A driven gear of the transmission mechanism is rotatably supported by first and second bearings. One of the first and second bearings includes an inner ring coupled so as to be rotatable together with an output shaft of a steering shaft, an outer ring held on a housing, and a rolling element interposed between the inner ring and the outer ring. One of the inner ring and the outer ring includes an annular elastic plate giving a preload to the rolling element.

摘要： A steering shock absorbing apparatus for motor vehicle according to the invention comprises a first universal joint for interconnecting a first end of an intermediate shaft and a steering shaft, and a second universal joint for interconnecting a second end of the intermediate shaft and an input shaft of a steering gear. The intermediate shaft includes a hollow bellows portion having slant convexes and slant concaves alternating with each other. A line interconnecting the joint centers of the first and second universal joints is tilted to the center axis of the intermediate shaft at a predetermined angle. At motor vehicle collision, a bending moment derived from an impact force of the collision is exerted on the intermediate shaft because the line is tilted. As a result, the intermediate shaft is bucklingly contracted at the bellows portion thereof.

摘要： A shock absorbing steering apparatus for motor vehicle includes an intermediate shaft including first and second ends. The intermediate shaft includes a hollow bellows portion having convexes and concaves alternating with each other. The convexes include at least one slant convex. A plane including a ridge line of the slant convex is tilted to a perpendicular plane perpendicular to a center axis of the intermediate shaft. As a result, a part of an axial force exerted on the intermediate shaft at a motor vehicle collision is converted to a bending force on the intermediate shaft.
