For the first time we search for the $��_{c2}(1D)$ in $e^+e^-\to��_{c2}(1D)$ at $\sqrt{s}$ = 10.52, 10.58, and 10.867 GeV with data samples of 89.5 fb$^{-1}$, 711 fb$^{-1}$, and 121.4 fb$^{-1}$, respectively, accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. No significant $��_{c2}(1D)$ signal is observed in the mass range between 3.8 and 3.88 GeV/$c^2$. The upper limit at 90\% confidence level on the product of the Born cross section for $e^+e^- \to ��_{c2}(1D)$ and branching fraction for $��_{c2}(1D)\to ��h_c(1P)$ is determined to be $��(e^+e^- \to ��_{c2}(1D)){\cal B}(��_{c2}(1D)\to ��h_c(1P))$ $
