CPC B62D 1/184 (2013.01) [B62D 1/185 (2013.01)] | 3 Claims |
1. A steering device comprising:
a telescopic steering shaft that extends in a first direction;
a steering column of a cylindrical outer shape configured to rotatably support the steering shaft;
a bracket including a first side plate and a second side plate that sandwich the steering column from a second direction orthogonal to the first direction; and
a fastening mechanism that has an operation lever and a fastening shaft penetrating the first side plate and the second side plate and configured to fasten the first side plate and the second side plate,
wherein
the steering column includes a lower column and an upper column that are relatively slidably coupled to each other in the first direction,
the upper column includes:
a clamp that has a slit extending in the first direction and that is configured to be externally slidably fitted to the lower column;
a cylindrical part that extends from the clamp and configured to support the steering shaft;
a pair of protrusions between which the slit is interposed, the protrusions protruding radially outward from the clamp and being fastened by the first side plate and the second side plate when fastened with the fastening mechanism and the protrusions having long grooves into which the fastening shaft is inserted and each of which extends in the first direction; 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 that is positioned near the cylindrical part and that is continuous with the cylindrical part; and
a spaced clamp that is spaced apart from the cylindrical part,
each of the protrusions includes:
a continuous protrusion that protrudes from the continuous clamp; and
a spaced protrusion that protrudes from the spaced clamp, and
a third direction is a direction perpendicular to both of the first direction and the second direction,
the reinforcement rib is disposed above the long grooves in the third direction,
the reinforcement rib is further disposed in the first direction between a first end and a second end of the long grooves in the first direction, and
the reinforcement rib is inclined in the third direction such that a part of the reinforcement rib is closer to the cylindrical part as the part of the reinforcement rib extends in the third direction, and linearly extends from one of the spaced protrusions toward the continuous clamp.
