FIELD: ironmongery, particularly locks. ^ SUBSTANCE: lock comprises body and rotating mechanism including rotary hub and central stepped core secured to hub. Coaxial radial orifices are formed in body and rotary hub. Orifices coaxial to radial key orifices are stepped, wherein step with greater diameter is located inside body, step with lesser diameter is located in rotary hub. Inserted in each orifice coaxial with key orifice are ball and limiter. Ball diameter exceeds rotary hub wall thickness. Limiter has a hole formed on limiter end facing ball. Inserted in each another orifice are two balls. Diameter of ball contacting with key is not more than rotary hub wall thickness and above orifices are arranged so that gravity force acting on balls arranged in these orifices are directed to cylinder mechanism center. Central core has holes formed on cylindrical surface thereof and coaxial to stepped orifices. ^ EFFECT: increased secrecy and workability. ^ 6 cl, 3 dwg |
