Steering Device

A steering device comprising:

• an inner column;
• an outer column arranged on a rear side of the inner column and externally fitted onto the inner column so that relative displacement is possible in an axial direction;
• and
• a support bracket having a mounting plate portion, and a pair of support plate portions each having an upper end portion fixed to a lower surface of the mounting plate portion, the pair of support plate portions arranged on both sides in a width direction of the outer column;
• the outer column including a pair of clamped portions arranged on both sides in the width direction of the inner column and configured to sandwich the inner column from both sides in the width direction due to elastic deformation in the width direction, and first tightened surfaces, second tightened surfaces, and third tightened surfaces configured to receive a tightening force from inside surfaces in the width direction of the pair of support plate portions;
• the first tightened surfaces arranged on outside surfaces in the width direction of the pair of clamped portions;
• the second tightened surfaces arranged on both sides in the width direction of a portion of the outer column that is located below the first tightened surfaces and has higher rigidity with respect to the width direction than the pair of clamped portions;
• the third tightened surface arranged on both sides in the width direction of a portion of the outer column that is located above the first tightened surfaces and has higher rigidity with respect to the width direction than the pair of clamped portions;
• a width dimension between the first tightened surfaces and a width dimension between the third tightened surfaces being equal to each other and larger than a width dimension between the second tightened surfaces;
• and
• at least one support plate portion of the pair of support plate portions including reinforcing portions arranged on both end portions in a front-rear direction thereof, the reinforcing portions extending in a vertical direction and each having a free end on an upper end portion thereof, and a stepped portion arranged in an intermediate portion in the front-rear direction thereof, the stepped portion having a concave shape on an outer side in the width direction, a convex shape on an inner side in the width direction, and an inside surface in the width direction facing the third tightened surface and configured to be brought in contact with only the third tightened surface.
