Abstract: 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.

Abstract: 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.

Abstract: Construction is achieved wherein the front-end section of an outer column 18a can be assembled in the rear-end section of a housing 11a that houses an electric power steering apparatus 10a from below. At least the front-end section of the outer column 18a is formed into a U shape that is open on the top end. A connection and fastening section 36 that can be inserted inside the front-end section of the outer column 18a through an opening on the top end of the front-end section is provided on the rear-end section of the housing 11a.

Abstract: Construction is achieved wherein the front-end section of an outer column 18a is assembled in the rear-end section of a housing 11a that houses an electric power steering apparatus 10a from below. A block shaped connection and fastening section 36 is provided on the rear-end section of the housing 11a. A pair of slits 37 is formed in portions of the connection and fastening section 36 near the left and right ends, and are open on the bottom end surface and rear end surface of the connection and fastening section 36. At least the front-end section of the outer column 18a has a pair of side plate sections 30 and a bottom plate section 31 that is formed in a U shape that is open at the top. The side plate sections 30 are inserted inside the slits 37 from below. In this state, the connection and fastening section 36 and the front-end section of the outer column 18a are connected and fastened by a bolt 39.

Abstract: Construction of an impact absorbing steering wheel apparatus that is capable of obtaining excellent performance at low cost while maintaining the freedom of design is achieved. An energy absorbing member 36a, 36b is provided between a tightening rod 27a that displaces in the forward direction together with an outer column 13a during a secondary collision and a housing 16 or support pin 63 that does not displace in the forward direction during a secondary collision, and being a member that plastically deforms as the outer column displaces in the forward direction during a secondary collision, absorbs part of the impact energy by the relative movement of the plastic deformation. Part of the energy absorbing member 36a, 36b is fastened to the tightening rod 27a, and plastic deformation of this member 36a, 36b is restricted in the width direction by a pair of held wall sections 11a of the outer column 13a.

Abstract: In a steering apparatus configured by including: a steering shaft to which a steering wheel can be fitted; a steering column supported on a vehicle body and supporting the steering shaft rotatably; and a combination switch fixedly fitted to the steering column and constructed by combining a plurality of switches having different functions into one integral unit, the improvement comprises: a spacer having an inner peripheral surface that is fixedly fitted onto an outer peripheral surface of an end portion of the steering column on a rear side with respect to a vehicle body and an outer peripheral surface that is formed to have a dimension of an outer diameter enabling an inner peripheral surface of a fitting portion provided in the combination switch to be fitted onto the outer peripheral surface; and a rotation preventive mechanism preventing the spacer from rotating about the steering column.
