Equation of motion for the galactic tide is derived under the assumption of cylindrically symmetric gravitational potential of the Galaxy .
The paper considers galactic tide both for the galactic plane x - and y - components and also for the normal z - component .
The x - and y - components of the acceleration come not only from the x - and y - components of the position of a body , but also from its z - component of the position vector .

Values of the Oort constants are A = ( 14.2 \pm 0.5 ) km~ { } s ^ { -1 } ~ { } kpc ^ { -1 } and B = ( - 12.4 \pm 0.5 ) km~ { } s ^ { -1 } ~ { } kpc ^ { -1 } .
Mass density in the solar neighborhood , 30 pc above the galactic equatorial plane , equals to ( 0.117 \pm 0.005 ) M _ { \odot } ~ { } pc ^ { -3 } .
The result for the acceleration is written in the form easily applicable to Solar System studies , to the evolution of comets in the Oort cloud .
