Abstract
A locking device with a key-actuated cylinder core has a cylinder guide rotationally supporting the cylinder core and stopping points for tumblers. One area of the cylinder guide is received axially fixed but rotatably in a housing, while the other area is surrounded by a sliding member non-rotatably but axially slidably supported on the cylinder guide. A turning member surrounds the sliding member and is rotatable relative to and synchronously axially movable with the sliding member. A spring acts axially on the turning member. An overload protection device has a control element arranged on the housing and a counter control element, arranged on the sliding member and spring-loaded against the control element, for axially moving the sliding and turning members in an overload situation to release an axial coupling having one coupling member fixedly connected to the cylinder core and another coupling member arranged on the turning member.
