PROBLEM TO BE SOLVED: To provide a vehicular steering device having a low-cost rotation restriction mechanism capable of changing a rotation operation amount of a steering component.SOLUTION: In a vehicular steering device including a rotation restriction mechanism 20 restricting a rotation operation amount of a steering component 2 to a prescribed angle or less, the rotation restriction mechanism 20 is formed with groove-shaped first grooves 33A, 33B, 33C in which an engagement member 21 can move in the radial direction of a steering shaft 11 according to rotation of a rotatable element 30 in one of the rotatable element 30 and a non-rotatable element 40, and is formed with a spiral groove-shaped second groove 43 having a length in which the rotation operation amount of the steering component 2 becomes a prescribed angle in the circumferential direction of the steering shaft 11 in the other of the rotatable element 30 and the non-rotatable element 40. The first grooves 33A, 33B, 33C have at least three points crossing the second groove 43, and one groove 33A, 33B, 33C, or two or more first grooves 33A, 33B, 33C have the engagement members 21. |
