Using the fiber bundle M over a manifold B, we define a semi-cotangent (pull-back) bundle t*B, which has a degenerate symplectic structure. We consider lifting problem of projectable geometric objects on M to the semi-cotangent bundle. Relations between lifted objects and a degenerate symplectic structure are also presented.
