In this paper we discuss the properties of the general covariant angular momentum of a five-dimensional brane-world model.Through calculating the total angular momentum of this model,we are able to analyze the properties of the total angular momentum in the in-ationary RS model.We show that the space-like components of the total angular momentum of the in-ationary RS model are all zero while the others are non-zero,which agrees with the results from ordinary RS model.
