dc.description.abstract	We determined the cluster’s apex coordinates, studied the substructures and performed membership analysis in the central part (34 ° x 33 °) of the open cluster M 67. We used the individual stellar apexes method developed earlier and classical technique of proper motion diagrams in coordinate system connected with apex. The neighbour-to-neighbour distance technique was applied to detect space details. The membership list was corrected and some stars were excluded from the most probable mem- bers list. The apex coordinates have been determined as: Aₒ = 132:97° ± 0:81° and Dₒ = 11:85 ° ± 0:90° . The 2D-space star density field was analysed and high degree of inhomogeneity was found.	en_US
