  The Local Void is the nearest void from us and is thought to be playing an
important role in the kinematics of the local universe, especially as one of
the suspected source of the motion of the Local Group. The imbalance between
the mass in the Local Void region and that contained in the concentration at
the opposite side might contribute to the velocity of the Local group
perpendicular to the Supergalactic plane, and this would be a prototype of the
evolution of the large-scale structure. The proximity of the Local Void
provides us the exclusive opportunity to investigate the kinematics around a
void. Here we report the results of our observational study of the peculiar
velocities of about 40 galaxies at the far-side of the Local Void, using the
near-infrared Tully-Fisher relation. The galaxies at the boundary of the void
shows an excess of receding motion, suggesting the expansion of the Local Void.
We examined the effect of selection biases on the peculiar velocity
distribution, and concluded that the excess of receding motion could not fully
attribute to selection biases.
