A steering column device comprising:

• a fixing bracket fixed to a vehicle body;
• a column jacket swingably supported in the fixing bracket;
• a steering shaft housed in the column jacket;
• a link mechanism pivotably supported with respect to the fixing bracket about a first pivot shaft, which is perpendicular to a center axis of the steering shaft and is positioned further toward an upper side of a vehicle than the center axis, and pivotably supported with respect to the column jacket about a second pivot shaft, which is positioned further toward the upper side of the vehicle than the center axis;
• a sliding member pivotably supported with respect to the link mechanism about the second pivot shaft;
• and
• a drive mechanism connected to the link mechanism to drive the link mechanism, thereby adjusting a tilt angle of the steering shaft,
• wherein the sliding member includes:
• a flanged collar configured with a collar portion and a flange portion and engaged in an elongated hole which is provided in a portion of the link mechanism which is near the second pivot shaft, and the flanged collar is pivotably supported in the elongated hole, and
• a shaft member configured with a shaft portion and a head portion, and the shaft member is pivotably supported in the flanged collar and fixed to the column jacket,
• and wherein a plurality of convex bodies engaged with the shaft portion of the shaft member are formed on an inner peripheral surface of the collar portion in the flanged collar, and a plurality of convex portions engaged with the head portion of the shaft member are formed on an outer side surface of the flange portion in the flanged collar.
