Let $\mathcal{S}^0_\mathcal{H}$ be the class of normalized univalent harmonic mappings in the unit disk. A subclass $\mathcal{V}^{\mathcal{H}}(k)$ of $\mathcal{S}^0_\mathcal{H}$, whose analytic part is function with bounded boundary rotation, is introduced. Some bounds for functionals, specially harmonic pre-Schwarzian derivative, described in $\mathcal{V}^{\mathcal{H}}(k)$ are given.
Keywords: univalent harmonic mappings, functions with bounded boundary rotation
