Results on the study of D(1285)→K + K − π 0 -decay are presented. The K + K − effective mass spectrum is measured with statistics which are by an order of magnitude higher than in the previous data. From the analysis of the differential spectrum d N d M KK (in the framework of the δ-dominance model) the δ-meson effective width is Γ δ >180MeV/ c 2 at √ s =1 GeV/ c 2 , which means a strong coupling of the δ-meson with hadrons.
