  We study Homological Mirror Symmetry (HMS) for $A_n$-resolutions from the SYZ
viewpoint. Let $X\to\bC^2/\bZ_{n+1}$ be the crepant resolution of the
$A_n$-singularity. The mirror of $X$ is given by a smoothing $\check{X}$ of
$\bC^2/\bZ_{n+1}$. Using SYZ transformations, we construct a geometric functor
from a derived Fukaya category of $\check{X}$ to the derived category of
coherent sheaves on $X$. We show that this is an equivalence of triangulated
categories onto a full triangulated subcategory of $D^b(X)$, thus realizing
Kontsevich's HMS conjecture by SYZ.
