Abstract
The lock bolt has a bolt tip (2) a bolt head (3) whose back wall (4) is intended to rest against a housing pin for sliding this pin into the rotary closure cylinder (24). The bolt tip (2) is supported on the bolt head (3) with a spring engaged between the bolt tip (2) and the bolt head (3) so that it can slide in a limited fashion between an inner and an outer position. The bolt head (3) has a longitudinal bore (5) in which the bolt tip (2) is supported so that it can slide. The lock bolt to a large extent prevents unlocking attempts in which vibrational movements are exerted on the tumblers.
