A processing method for a metal plate includes a curve surface forming recess forming step, a protruding step, and, a shaping and dividing step. In the curve surface forming recess forming step, a recess is formed in the metal plate, the recess having an outer periphery forming a curve surface, a side portion formed in a frustum, and a bottom portion being round. In the protruding step, a portion of the recess from the bottom portion to the side portion is protruded toward an inside of the recess, and the side portion of the recess is formed to be close to a center of the recess. In the shaping and dividing step, the protruded portion and the outer periphery of the recess are shaped so that the recess is divided into a group of the plural recess portions adjacent to each other.

A steering column includes a jacket tube with a clamping section with a slot extending longitudinally. A clamping collar has transversely opposed legs are interconnected via an arcuate section between which the clamping section of the jacket tube is at least partially accommodated. An actuating unit is arranged in the jacket tube, with a steering spindle rotatably mounted therein around the longitudinal axis. A clamp fixes the actuating unit longitudinally relative to the jacket tube and in a release position unclamps the clamping collar and frees the actuating unit longitudinally and presses the legs toward each other transversely to the longitudinal axis in the fixing position. Driver elements are arranged on the jacket tube in opposite edge regions of the slot, and the legs include contact elements which in the fixing position can be pressed against the outer sides of the driver elements.
