Using a sample of 102 million $\Upsilon(1S)$ events collected with the Belle detector, we report on the first search for charge-parity-even charmonium and charmonium-like states in $\Upsilon(1S)$ radiative decays. No significant $\chi_{cJ}$ or $\eta_c$ signal is observed and 90% C.L. limits on $\BR(\Upsilon(1S)\to \gamma \chi_{c0})<6.5 \times 10^{-4}$, $\BR(\Upsilon(1S)\to \gamma \chi_{c1})<2.3\times 10^{-5}$, $\BR(\Upsilon(1S)\to \gamma \chi_{c2})<7.6 \times 10^{-6}$, and $\BR(\Upsilon(1S)\to \gamma \eta_c)<5.7\times 10^{-5}$ are obtained. The product branching fraction limits $\BR(\Upsilon(1S)\to \gamma X(3872)) \BR(X(3872)\to\pi^+\pi^-\jpsi)< 1.6 \times 10^{-6}$, $\BR(\Upsilon(1S)\to \gamma X(3872)) \BR(X(3872)\to\pi^+\pi^-\pi^0 \jpsi)< ...
