We study positive definite quaternionic contact $(4n+3)$-manifolds($qc$-manifold for short). Just like the $CR$-structure contains the class ofSasaki manifolds, the $qc$-structure admits a class of $3$-Sasaki manifoldswith integrable distribution isomorphic to $\mathfrak{su}(2)$. A big differenceconcerning the integrable complementary $qc$-distribution $V$ of the$qc$-structure from $3$-Sasaki structure is the existence of Lie algebra notisomorphic to $\mathfrak{su}(2)$. We take up non-compact $qc$-manifolds to findout a salient feature of topology and geometry in case $V$ generates the$qc$-transformations $R^3$.
