IRAS sources
in the galactic disk, 
and 
,
have been observed in the SiO maser lines and near-infrared
J, H, and K bands.
These sources are in the direction
of the near end of the galactic bar.
The measured J, H, and K magnitudes were used to obtain
bolometric corrections for the objects. Assuming a constant
luminosity for these sources, we calculated the luminosity distances to the
sources. Combining the distances with the radial velocities
obtained by SiO maser observations, we found that the sources with
distances of about 5.5 kpc from the Sun exhibit a large deviation
from the galactic rotation. The large standard deviation of the
radial velocities for stars at around 5.5 kpc might be explained
by some effect in a bar potential of the Galaxy.
