摘要： A steering apparatus includes an input shaft that transmits a steering force input from a steering wheel and an output shaft that transmits a steered force by which wheels are steered. The output shaft is arranged at a position that is radially offset from the input shaft. One of an eccentric cam and an adapting plate that form an eccentric pin mechanism is connected to the input shaft. The output shaft is connected to the other one of the eccentric cam and the adapting plate. A first connecting portion of the input shaft, which is connected to the eccentric pin mechanism, is connectable to a second connecting portion of the output shaft, which is connected to the eccentric pin mechanism.

摘要： A cam follower includes an oval rotational body which is rotationally supported on a fixed pin, and in which an outer circumferential shape thereof is an oval, a long axis of the oval is longer than a width of the cam groove, and a short axis of the oval is shorter than the width of the cam groove, the oval rotational body being biased and being rotated by a biasing spring in one direction about the fixed pin. As a consequence, when a steering wheel is in a neutral position, the outer circumferential surface of the cam follower comes into contact with both side surfaces of the cam groove in the width direction of the cam groove and gaps therebetween can be eliminated. As a result, neutral stability of the steering wheel and steering feeling during straightforward traveling are improved.

摘要： A steering apparatus includes: an input shaft that transmits a steering force input from a steering wheel; an output shaft that transmits a steered force by which wheels are steered; and an eccentric pin mechanism that includes an eccentric cam and an adapting plate. The output shaft is arranged at a position that is radially offset from the input shaft, and is connected to one of the eccentric cam and the adapting plate. The other one of the eccentric cam and the adapting plate is connected to the input shaft. A middle accommodation member that accommodates the eccentric pin mechanism is formed separately from an input-side accommodation member that accommodates the input shaft and an output-side accommodation member that accommodates the output shaft.

摘要： A steering apparatus includes a first shaft coupled to a steering wheel, a second shaft arranged to be eccentric relative to the first shaft, and a joint mechanism for coupling the first shaft and the second shaft to each other. The joint mechanism includes a cam having a cam groove that extends in a direction perpendicular to the first shaft, a cam follower that can slide in the cam groove, an eccentric pin for coupling the second shaft and the cam follower to each other at a position eccentric relative to the second shaft. An outer cylinder serving as a protective member is arranged concentrically with the eccentric pin, so as to surround the outer circumference of the eccentric pin. At least part of the eccentric pin and the outer cylinder is arranged in the cam groove.

摘要： A steering-force transmitting apparatus including (a) an operating-member-side shaft; (b) a turning-device-side shaft offset from the operating-member-side shaft; and (c) a rotation transmitting mechanism having (c-1) an axially protruding portion provided in one of the two shafts and (c-2) a radially extending groove provided in the other of the two shafts such that the axially protruding portion is engaged in the radially extending groove. The rotation transmitting mechanism is configured to change a rotational phase difference between the two shafts while causing one of the two shafts to be rotated by rotation of the other of the two shafts. An axially end portion of a main body portion of one of the two shafts and an axially end portion of the other of the two shafts overlap with each other in the axial direction.
