STEERING COLUMN DEVICE

Construction is achieved wherein upward displacement of a steering column 6c during a secondary collision is prevented, and the distance D between the steering column 6c and the tip end section of an adjustment lever 18b is kept the same regardless of the up/down position of the steering wheel 1. The position of the adjustment lever 18b after rotation is maintained by the tip end section of a locking arm 40 that is provided on the base end section of the adjustment arm 18b engaging with a locking groove 42 of a locking piece 41 that is provided on a support plate section 23a. The direction of formation of the locking groove 42 is such that when the up/down position of the steering wheel 1 is in an upward position, the top end section of the locking groove 42 engages with the tip end section of the locking arm 40, and when the up/down position of the steering wheel 1 is in a downward position, the bottom end section of the locking groove 42 engages with the tip end section of the locking arm 40.
