  In spite of the fact that the two-body $B$ decays into $\chi_{c2}$ such as $B
\to \chi_{c2} K^{(*)}$ are suppressed by the QCD factorization effect, the
inclusive $B \to \chi_{c2} X$ branching fraction amounts to one third of the
non-suppressed $B \to \chi_{c1} X$ decays because of the decay modes to the
multi-body final states. Using a large statistics $\Upsilon(4S)$ data sample
corresponding to 772 million $B$ meson pairs accumulated by the Belle detector
at the KEKB $e^+e^-$ collider, precise measurements of inclusive $B \to
\chi_{c1}$ and $\chi_{c2}$ branching fractions are carried out. The multi-body
final states such as $\chi_{cJ} K \pi$, $\chi_{cJ} K \pi \pi$ and so on are
also investigated to look for new charmonium-like resonance.
