Abstract

A steering device includes: an inner tube; an outer tube that fixes the inner tube by fastening the inner tube from an outer side, and has a first slit extending in an axial direction; a pair of clamp brackets that is disposed so that the clamp brackets face each other with the first slit therebetween; and a reinforcing member that is connected to one of the clamp brackets and also connected to a connection region that is a region of an outer circumferential surface of the outer tube and located farther on one side in the axial direction than an end of the first slit on the one side in the axial direction.

First claim

What is claimed is:

1. A steering device comprising:
an inner tube extending in an axial direction;
an outer tube that fixes the inner tube by fastening an end of the inner tube on one side in the axial direction from an outer side, and that has a first slit extending through the outer tube between an inner circumferential surface and an outer circumferential surface thereof and extending in the axial direction;
a pair of clamp brackets that is disposed so that the clamp brackets face each other with the first slit therebetween, and that extends from the outer circumferential surface of the outer tube in a direction intersecting the axial direction; and
a reinforcing member including:
a bracket connecting part that is connected to one of the clamp brackets and is spaced from the outer tube in a radial direction; and
a tube connection part that extends in the radial direction from a first end connected to a connection region of the outer tube to a second end connected to the bracket connecting part, the connection region of the outer tube being a region of the outer circumferential surface of the outer tube located farther on the one side in the axial direction than an end of the first slit on the one side in the axial direction.

2. The steering device according to claim 1 , further comprising:
a tilt bracket that holds the clamp brackets in a direction in which the clamp brackets face each other; and
an upper bracket that is fixed to the tilt bracket and also configured to be fixed to a frame of a vehicle equipped with the steering device.

3. The steering device according to claim 1 , wherein the outer tube has a second slit extending through the outer tube between the inner circumferential surface and the outer circumferential surface thereof; the second slit extending in a direction intersecting an extension direction of the first slit and being connected to the end of the first slit on the one side in the axial direction.

4. The steering device according to claim 3 , wherein a length of the tube connection part in an extension direction of the second slit is smaller than a length of the second slit in the extension direction of the second slit.

5. The steering device according to claim 1 , wherein the outer tube has a key lock hole which is located farther on the one side in the axial direction than the connection region of the outer tube and extends through the outer tube between the inner circumferential surface and the outer circumferential surface thereof, the key lock hole being configured such that a lock key of a steering lock device of a vehicle equipped with the steering device can be inserted.

6. A steering device comprising:
an inner tube extending in an axial direction;
an outer tube that fixes the inner tube by fastening an end of the inner tube on one side in the axial direction from an outer side, the outer tube comprising:
a first slit extending through the outer tube between an inner circumferential surface and an outer circumferential surface thereof and extending in the axial direction; and
a second slit extending through the outer tube between the inner circumferential surface and the outer circumferential surface thereof, the second slit extending in a direction intersecting an extension direction of the first slit and being connected to the end of the first slit on the one side in the axial direction;

a pair of clamp brackets that is disposed so that the clamp brackets face each other with the first slit therebetween, and that extends from the outer circumferential surface of the outer tube in a direction intersecting the axial direction; and
a reinforcing member that is connected to one of the clamp brackets and includes a tube connection part connected to a connection region that is a region of the outer circumferential surface of the outer tube and located farther on the one side in the axial direction than an end of the first slit on the one side in the axial direction, a length of the tube connection part in an extension direction of the second slit being smaller than a length of the second slit in the extension direction of the second slit.
