  The field-induced transition corresponding to the spin flop in the quantum
antiferromagnetic chains in the presence of the Ising-like single-ion
anisotropy D (<0) is studied by the finite-cluster analysis. It is found that
for $S\geq {3\over 2}$ a first-order metamagnetic transition occurs even in one
dimension for small negative D except for the Haldane phase, while there exist
two second-order transitions and an incommensurate phase appears between them
for intermediate D, as already found for S=1. We also discuss on some
experiments of CsNiCl$_3$ related with the present work.
