  We report results on the Dalitz analysis of three-body charmless
B+=>K+pi+pi-, B0=>K0pi+pi- and B+=>K+K+K- decays including searches for direct
CP violation in the B+=>K+pi+pi- mode. Branching fractions for a number of
quasi-two-body intermediate states are reported. We also observe evidence with
3.9 sigma significance for a large direct CP violation in B+-=>rho(770)0K+-
channel. This is the first evidence for CP violation in a charged meson decay.
The results are obtained using a Dalitz analysis technique with a large data
sample of BBbar pairs collected with the Belle detector operating at the KEKB
asymmetric energy e+e- collider.
