It was found that the angular velocity of Galactic rotation in the solar vicinity decreases to 25.6 km s-1 kpc-1 for clusters older than 600 Myrs. According to the rotation curves of the Galaxy for different age intervals at a galactocentric distance of 6.0 to 13.0 kpc, it is found that older open clusters rotate much more slowly than young and middle-aged clusters. The rotation curve decreases with increasing galactocentric distance in the entire distance interval under consideration.
