FIELD: locking devices, particularly locks to protect flats, service rooms, cars, safes and other closed spaces. ^ SUBSTANCE: lock comprises body made as cup and adapted to receive cylinder so that the cylinder may rotate about axis. Lock also has locking pins, pushers brought into contact therewith and having ends with lengths exceeding pusher diameters, as well as key with extensions. Cylindrical support ledge is arranged inside cylinder so that the support ledge may rotate about its axis. Key channel is formed in the ledge, wherein the support ledge is restrained from sliding along cylinder axis. Pusher ends abut upon support ledge surface. One end of support axis projects upwards and passes through orifice formed in body so that the cylinder may be unbraked by support ledge key rotation when cylinder is fixed with further simultaneous support extension and cylinder rotation. ^ EFFECT: increased breaking-in resistance of cylinder mechanism. ^ 2 cl, 5 dwg
