  We study the confinement-induced resonance (CIR) of $^{173}$Yb atoms near an
orbital Feshbach resonance in a quasi-one-dimensional tube with transversal
anisotropy. By solving the two-body scattering problem, we obtain the location
of CIR for various anisotropy ratio and magnetic field. Our results show that
the anisotropy of the trapping potential can serve as an additional knob to
tune the location of CIR. In particular, one can shift the location of CIR to
the region attainable in current experiment. We also study the energy spectrum
of the system and analyze the properties of CIR from the perspective of bound
states. We find that as the orbital Feshbach resonance acquires two nearly
degenerate scattering channels, which in general have different threshold
energies, CIR takes place when the closed channel bound state energy becomes
degenerate with one of the thresholds.
