摘要： Construction of a tilt steering apparatus is provided that is capable of preventing the occurrence of unpleasant noise during height adjustment of a steering wheel 1, and maintains sufficient durability and smooth operation. The tilt steering apparatus of the present invention is provided with stoppers 65 in at least two locations in a buffer member 21 c that are rotationally symmetric about the center axis of an adjustment rod 14, and that when a driven-side cam 15b is rotated as the axial dimension of a cam apparatus 47 is expanded or contracted, controls rotation of the driven-side cam 15b so that a convex engaging portion 39c does not collide with the front-side edge or rear-side edge of a vertically long hole 35b.

摘要： To provide a steering device that reduces a hitting sound occurring upon release of clamping by a clamp mechanism and has high operability. A steering device including a clamp mechanism including: a shaft rod bridged across a vehicle-body attachment bracket supporting a steering column; a fixed cam member and a movable cam member configured to cause mutually opposing cam protrusions to be engaged with each other, and axially move the shaft rod in cooperation with each other; and an operation lever for moving the movable cam member. A buffer member is provided between first stopper portions of the fixed cam member and second stopper portions of the movable cam member.
