STEERING DEVICE

PROBLEM TO BE SOLVED: To provide a steering device for suppressing various influences due to the rotational load of an upper jacket.SOLUTION: A first tooth member 60 includes a pair of first tooth rows 62L spaced in an orthogonal direction relative to a column axial direction X. A second tooth member 70 includes a body part 73, and a tooth forming part 75 having a second tooth 74. A guide mechanism 80 includes: a guide shaft 81 inserted into a long hole 82 of the body part 73 and supported by a pair of support parts 160; and a pair of slide guide faces 161 formed on the paired support parts 160 for sliding and guiding a pair of guided faces 73c of the body part 73. As viewed from the column axial direction X, each of the guided faces 73c contains a protruding curved portion 83 protruding to the sides of the slide guide faces 161. When the upper jacket 15 performs a rotational displacement, only the slide guide faces 161 on the side of the rotation direction R1 abut against the protruding curved portion 83.SELECTED DRAWING: Figure 8 【課題】アッパージャケットの回転負荷による諸影響を抑制するステアリング装置を提供する。【解決手段】第１ツース部材６０が、コラム軸方向Ｘに対する直交方向に離隔して向き合う一対の第１ツース列６２Ｌを含む。第２ツース部材７０は、本体部７３と、第２ツース７４を有するツース形成部７５とを含む。案内機構８０が、本体部７３の長孔８２に挿通され一対の支持部１６０によって支持された案内軸８１と、一対の支持部１６０に設けられ本体部７３の一対の被案内面７３ｃを摺動案内する一対の摺動案内面１６１とを含む。コラム軸方向Ｘから見て、各被案内面７３ｃは、摺動案内面１６１側に突出する凸湾曲部８３を含む。アッパージャケット１５が回転変位するときに、回転方向Ｒ１側の摺動案内面１６１のみが凸湾曲部８３と当接する。【選択図】図８
