Abstract: To construct the embedded subbundles of free bundles and the embedded free subbundles of any module bundles, by using embedded relation of module bundles. It is indicated that any module bundles can becomes a embedded subbundles of free bundles,and that there is a free bundles (or projective bundles) is a embedded subbundles of any module bundles also. In particular, the condition which projective bundles change into free bundles is given.

Key words: Fibre bundles, Module bundles, Immersed subbundles, Embedded subbundles.
