We investigate special regularity of solutions to the initial value problem associated to the nonlinear fifth order equation of KdV type. The main results show that for datum $u_{0} \in H^{s}({\bf R}), F(u) \in C^{s+2}({\bf R})$ with $s\geq5$, whose restriction belongs to $H^{l}((x_{0}, \infty))$ and $H^{l+2}((x_{0}, \infty))$ respectively, for some $l \in \mathbb{Z}^{+}$ and $x_{0}\in {\bf R}$, then the restriction of the corresponding solution $u(\cdot, t)$ belongs to $H^{l}((b, \infty))$ for any $b\in{\bf R}$ and any $t\in (0, T)$. Thus, this type of regularity travels with infinite speed to its left as time evolves. To a certain extent, our results complement the previous studies on the related aspects, and deepen the understanding of such properties for the dispersion equation.
