Steering column apparatus

A steering column apparatus comprising:

• a column shaft to which a steering wheel is fixed at a rear end in a front-rear direction of a vehicle;
• a column tube that supports the column shaft such that the column shaft is rotatable;
• and
• an upper bracket that supports a rear part of the column tube, wherein
• the column tube includes:
• a lower tube;
• and
• an upper tube fitted to the lower tube from a rear side,
• the upper bracket includes:
• a vehicle body-side bracket fixed to a vehicle body and including a pair of side plates provided at a distance between the side plates in a width direction of the vehicle;
• a tube-side bracket fixed to the upper tube and including a pair of side plates provided at a distance between the side plates in the width direction of the vehicle;
• and
• a support shaft arranged below the upper tube,
• the vehicle body-side bracket has first coupling holes in the respective side plates,
• the tube-side bracket has second coupling holes in the respective side plates,
• the first coupling holes and the second coupling holes are configured such that the vehicle body-side bracket and the tube-side bracket are coupled together by inserting the support shaft through the first coupling holes and the second coupling holes, and
• each of the second coupling holes is open rearward and is configured such that, when an axial load equal to or greater than a predetermined load is applied to the upper tube, fitting between the second coupling hole and the support shaft is terminated and the tube-side bracket moves forward.
