Steering system

A steering system configured to perform tilt adjustment, the steering system comprising:

• a steering shaft to which a steering member is coupled at one end;
• a fixed bracket that is fixed to a vehicle body and includes a first side plate and a second side plate each having an insertion hole;
• a column jacket that supports the steering shaft so that the steering shaft is rotatable, the column jacket is disposed between the first side plate and the second side plate, and the column jacket is configured to move relative to the fixed bracket during the tilt adjustment;
• and
• a lock mechanism configured to lock a position of the column jacket relative to the fixed bracket after the tilt adjustment, wherein
• the lock mechanism includes:
• an insertion shaft inserted through the insertion hole of the first side plate and the insertion hole of the second side plate;
• an operation member that is supported on the insertion shaft and is operable rotationally;
• a first pressing member configured to press the first side plate to push the first side plate against the column jacket;
• a second pressing member configured to press the column jacket by extending through the insertion hole of the second side plate to directly contact and push the column jacket against the first side plate;
• and
• a drive mechanism configured to move at least one of the first pressing member and the second pressing member so that the first pressing member and the second pressing member approach each other in an insertion axis direction of the insertion shaft when the operation member is rotated.
