The cable block-locking mechanism includes a stud slidably mounted to the cable block for selectively connecting the cable block with the lever housing, a push rod formed on the lever bracket for depressing the stud so as to release the cable block from the lever housing in an automatic mode, and a return spring mounted around the stud for returning the stud to its place so as to couple the cable block with the lever housing in a manual mode.
Abstract: A clearance-adjusting mechanism is provided so that a clearance in a circumferential direction between an inner wall surface of a boss section and an outer wall surface of a spline shaft section is adjusted in such a way that a first spline shaft member and a second spline shaft member, which are divided into two, are rotated and displaced in mutually opposite directions about a center of rotation of an axis.
Abstract: Using a phase matching device 59, the phases of the outside diameter side and inside diameter side ball spline grooves 46, 47 are matched to each other and such phase matched state is maintained as it is. A given number of balls are supplied to between the two ball spline grooves 46, 47 through openings formed in the upper end portions of spaces existing therebetween by a ball supply device 64. An input shaft 15 and an input side disk 2B are shifted reciprocatingly with respect to each other in the axial direction thereof and in the circumferential direction thereof using a lift board 54, a center pin 56, and a swing device 72. As a result of the relatively shifting operation of the input shaft 15 and input side disk 2B, the balls are allowed to drop into the lower portions of spaces respectively defined by and between the two ball spline grooves 46, 47 due to the influence of gravity, that is, due to their own weights.

Abstract: An electric steering column for a motor vehicle is provided, which has a steering shaft. A jacket tube extends along the steering shaft to cover the same. A worm wheel is rotatably held by the jacket tube and has a center bore through which a given portion of the steering shaft loosely passes. A collar member is tightly disposed on the given portion of the steering shaft defining an annular clearance between the collar member and the worm wheel. An elastically deformable structure is put and compressed in the annular clearance in such a manner as to induce a rotation of the collar member when the worm wheel is rotated. An electric motor rotates the worm wheel with an electric power. Due to provision of the elastically deformable structure, a possible ill-alignment between the worm wheel and the collar member is absorbed or compensated.
