FIELD: ironmongery, particularly locking cylinders for cars. ^ SUBSTANCE: locking cylinder comprises body with inner cylindrical cavity arranged to receive core. The core is provided with key channel and is spring-loaded by slides so that if the key channel is free of authorized key locking slide extensions are inserted in locking groove formed in member in which locking cylinder core is rotationally installed. If authorized key is installed in the key channel the locking slide extensions does not project from cylinder core outline. The locking cylinder is also provided with means which connects cylinder core with output link thereof if the core is rotated by authorized key and means, which disconnects the cylinder core from the output link if the core is rotated by non-authorized key or force is applied thereto during rotation. Inner cylindrical cavity of the body is provided with turnable annular grooves. A least one stop groove interrupts at least one extension defining the turnable annular groove from side opposite to axial direction of cylinder core detachment from output link. Locking groove sides expand in axial direction of cylinder core detachment from output link. ^ EFFECT: increased breaking-in resistance. ^ 10 cl, 18 dwg |
