We investigate the ground-state phase diagram for the ferromagnetic Kondo lattice model on the triangular lattice by a variational calculation for various spin orderings up to four-site unit cell. We find that a noncoplanar four-sublattice ordering with a finite scalar spin chirality emerges at and around 1/4 filling, in addition to the 3/4-filled case which was predicted to be induced by the perfect nesting of Fermi surface [I. Martin and C. D. Batista: Phys. Rev. Lett. {\bf 101} (2008) 156402]. The 1/4-filling phase is stable in a wider range of parameters than the 3/4-filling one, and includes a gapped insulating state characterized by a Chern number. We also show that the chiral-ordered phases exhibit the anomalous Hall effect.
