  • Patent number: 11970204
    Abstract: A steering device includes a steering column for supporting a steering shaft coupled to a steering wheel; an upper bracket fixed to a vehicle body and supports the steering column; and two lower brackets independently fixed to the vehicle body on both sides of the steering column to support the steering column in such a manner that allows the steering column to sway in a vertical direction. The lower brackets each includes a fixed portion facing the vehicle body and disposed on an outside of the steering column in a vehicle width direction, a pivot portion facing the steering column and having an attachment hole into which a pin member for coupling the steering column to the lower bracket is inserted, and a pair of rib portions each connected to the fixed portion and the pivot portion by a bent portion shaped into a bent plate.

  • Patent number: 11912333
    Abstract: A steering device includes a steering shaft, a steering column, a bracket, and a fastening mechanism. An upper column includes a clamp, a cylindrical part, a pair of protrusions, and contact ribs. The clamp includes a continuous clamp and a spaced clamp. The protrusions include a continuous protrusion and a spaced protrusion. The contact ribs include first contact ribs disposed each of which is disposed on the outer peripheral surface of the clamp, second contact ribs each of which is disposed on a side surface of the protrusion and disposed opposite to the first contact rib with respect to a long groove, and at least one third contact rib disposed on a side surface of the spaced protrusion and between the first contact rib and the long groove. The third contact rib has a protrusion amount greater than those of the first contact rib and the second contact rib.

  • Publication number: 20230143956
    Abstract: A steering device includes a telescopic steering shaft that extends in a first direction, and a cylindrical outer steering column that rotatably supports the steering shaft. The steering column includes a lower column and an upper column having one end slidably attached to the lower column and the other end on which a bearing that supports the steering shaft is provided. The upper column includes a clamp that is externally slidably fitted to the lower column and that has a slit extending in the first direction, and a cylindrical part that has a cylindrical shape and that has one end continuous with the clamp and the other end blocked by the bearing being internally fitted. The cylindrical part has an air hole that is spaced apart from the one end of the cylindrical part and that penetrates an outer peripheral surface and an inner peripheral surface of the cylindrical part.

  • Publication number: 20230143959
    Abstract: The steering device includes a steering shaft, a steering column, a bracket, and a fastening mechanism. The steering column includes a lower column and an upper column. The upper column includes a clamp, a cylindrical part, a pair of protrusions, and a reinforcement rib that extends across an outer peripheral surface of the clamp and an outer surface of one of the protrusions. The clamp includes a continuous clamp positioned near the cylindrical part and a spaced clamp spaced apart from the cylindrical part. The protrusions include a continuous protrusion that protrudes from the continuous clamp, and a spaced protrusion that protrudes from the spaced clamp. The reinforcement rib linearly extends from the spaced protrusion toward the continuous clamp.

  • Patent number: 8955883
    Abstract: When the guide bracket 61 is fixed to the vehicle-mounting bracket 21 by the guide pin 71, the upper surfaces 24c, 24c of the capsules 24, 24 are in contact with the lower surfaces 61c, 61c of the flange portions 61b, 61b on the guide bracket 61, and the first engaging portions 64, 64 and the second engaging portions 65, 65 engage with the capsules 24, 24. As a result, even before fixing the vehicle-mounting bracket 21 and the guide bracket 61 to the vehicle body 41 by the bolt 22, the guide bracket 61 does not rotate with respect to the vehicle-mounting bracket 21 about the guide pin 71, or move in the forward and rearward direction, or in the vehicle body width direction.
