An effort has been made to search for the decoupled bands in odd-odd 174Re via the 159Tb(20Ne,5n$\gamma $)174Re reaction through excitation functions, K x-$\gamma $ and $\gamma $-$\gamma $coincidence measurements. The doubly decoupled band and the semidecoupled one have been found in this work. Their quasiparticle configurations are proposed to be $\pi 1/2^{-}[541]\otimes \nu 1/2^{-}[521]$ and $\pi 1/2^{-}[541]\otimes $ $\nu i_{13/2}$, respectively, according to the characteristics of band structures in this mass region. Another band with strongly coupled character is also reported.
