Let (T1M, g(1)) be a unit tangent bundle of some surface (M, g) endowed with the induced Sasaki metric. In this paper, we define two kinds of curves called N-legendre and N-slant curves in which the inner product of its normal vector and Reeb vector is, respectively, equal to zero and to non-zero constant in (T1M, g(1)). Some several important characterizations of these curves are also obtained.
