  The reported transverse wobbling band in odd-mass $^{105}$Pd has been
reinvestigated by the triaxial particle rotor model. Employing different
parameter sets of moment of inertia (MOI), several calculated results could be
in good agreement with the experimental data, which show distinct modes of
rotational excitation, respectively. These modes are sensitive to the ratio
between the MOI at intermediate and short axis. With the increase of this
ratio, a wobble about the short axis of the total angular momentum is gradually
changed to a wobble about the intermediate axis. In addition, it is exhibited
that precession and tunneling are two aspects of the quantum wobbling motion.
The tunneling aspect dominates in the yrare states of $^{105}$Pd. The present
results in $^{105}$Pd show the complexity of the transverse wobbling mode.
