We define the notion of almost metrical 2 − π structure on the tangent bundle and study the main properties of such a structure. We study here the existence and arbitrariness of a d-connection FΓ(N) and determine all these connections. Finally we determine the infinitesimal motions of this structure and study the properties of these motions.
