Abstract: Based on data of world network neutron monitors and muon telescopes at Yakutsk and Nagoya stations an anisotropy component of galactic cosmic rays directed across a mean field line (in the direction of 15 LT) has been revealed. This component undergoes the 11-year variation. Its value rises with increasing the interplanetary magnetic field intensity, solar activity level and neutral sheet deformation. Such a property of this component is explained by the action of the vortex electric field in the heliosphere. The 22-year variation of an anisotropy component directed along the magnetic field is of drift origin.
