Electric steering lock

The electric steering lock has a light-weight housing (2) for the installation in a steering column-sided housing support, where the housing has a housing lower part (5), at which a drive unit and a locking pin (15) are arranged. The housing lower part has a passage opening for the locking bolt and partial guide elements (6) which not fully enclose the locking pin cross section. The guide elements are protruded at the outer side of the housing lower part. An independent claim is included for a housing support with guide flanks.
