  We investigate the distance-redshift relation in the simple void model. As
discussed by Moffat and Tatarski, if the observer stays at the center of the
void, the observed Hubble parameter is not so different from the background
Hubble parameter. However, if the position of observer is off center of the
void, we must consider the peculiar velocity correction which is measured by
the observed dipole anisotropy of cosmic microwave background. This peculiar
velocity correction for the redshift is crucial to determine the Hubble
parameter and we shall discuss this effect. Further the results of Turner et al
by the N-body simulation will be also considered.
