  • Publication number: 20050104353
    Abstract: An outer column (21) is held between a tension member (13) and brackets (12) by operating a lever (L), thereby making it possible to block displacements of fixing members (16, 17) along tilt grooves (12a). An inner column (11) is held to the brackets (12) through the outer column (21), whereby the displacements of the fixing members (16, 17) along telescopic grooves (11a) can be blocked. A steering shaft (S) can be thereby fixed in a tilting direction and a telescoping direction. The brackets (12) apply a pressing force to the inner column (11) through flange portions (21c, 21d) of the outer column (21) by operating the lever (L), and the inner column (11) receives the pressing force in a direction opposite to a direction in which the tension member (13) approaches. As rigidities of the pair of brackets (12) are approximately equal, a central position of the inner column (11) can be therefore kept substantially fixed. Hence, an axis deviation of the steering shaft (S) can be effectively restrained.

  • Patent number: 6467807
    Abstract: A steering device for a car comprises an inner column for rotatably supporting one end of a steering shaft, an outer column for rotatably supporting the other end of the steering shaft, in which the inner column is slidably fitted, a couple of clamp portions formed integrally with the outer column and each having an embracing surface for embracing the inner column, and a fastening mechanism for making the couple of clamp portions embrace and thus fasten the inner column by moving the couple of clamp portions close to each other. The steering shaft is moved in the axial direction by releasing the fastening mechanism so that a telescopic position of the steering shaft is adjustable.

  • Patent number: 6443650
    Abstract: A connection structure of a yoke and a shaft comprises a shaft including a pair of flat surfaces formed in parallel to each other on an outer peripheral surface of a front side end thereof, a yoke having a connection portion, formed at one side end thereof, for connecting the shaft, and having the other side end connected to a universal joint. The connection portion includes holding members, for holding the flat surfaces of the shaft, taking substantially a U-shape in section within a plane orthogonal to an axial direction thereof, a screw hole formed in the vicinity of one side end of the U-shape, and a bolt hole formed in the vicinity of the other side end thereof, concentric with the screw hole and having a diameter larger than the screw hole.
