  Vector magnetic fields of moving magnetic features (MMFs) are well observed
with the Solar Optical Telescope (SOT) aboard the Hinode satellite. We focus on
the evolution of three MMFs with the SOT in this study. We found that an MMF
having relatively vertical fields with polarity same as the sunspot is detached
from the penumbra around the granules appeared in the outer penumbra. This
suggests that granular motions in the outer penumbra are responsible for the
disintegration of the sunspot. Two MMFs with polarity opposite to the sunspot
are located around the outer edge of horizontal fields extending from the
penumbra. This is an evidence that the MMFs with polarity opposite to the
sunspot are prolongation of penumbral horizontal fields. Radshifts larger than
sonic velocity in the photosphere are detected for some of the MMFs with
polarity opposite to the sunspot.
