Abstract: When adjusting the forward-backward position of a steering wheel, together with reducing any uncomfortable feeling experienced by the driver, a support bracket is prevented from breaking away toward the front due to an extremely large force applied during the adjustment operation. Elastic sleeves 35 are mounted inside the long holes 25a in the forward-backward direction, and an adjustment rod 19a is inserted through the inside of the elastic sleeves 35. Gaps 36 located between the outer circumferential surface of both end portions in the forward-backward direction of the elastic sleeves 35 and the inner circumferential surface of the both end portions in the forward-backward direction of the long holes 25a in the forward-backward direction. When adjusting the forward-backward position the steering wheel, the adjustment rod 19a forcibly displaces toward the end portions in the forward-backward direction of the long holes 25a in the forward-backward direction, and when forcibly colliding with the inner circumferential surface of the end portions in the forward-backward direction of the elastic sleeves 35, the gaps 36 reduce the impact that is applied to the inner circumferential surface of the end portions of the long holes 25a in the forward-backward direction from the adjustment rod 19a by increasing the amount that the end portions of the elastic sleeves 35 elastically deform.
