We have found the precise stability region of the half quantum vortex (HQV) for superfluid $^{3}\text{H}\text{e}\ensuremath{-}A$ phase confined in parallel plates with a narrow gap under rotation. Standard Ginzburg-Landau free energy, which is well established, is solved to locate the stability region spanned by temperature $T$ and rotation speed $(\ensuremath{\Omega})$. This $\ensuremath{\Omega}\text{\ensuremath{-}}T$ stability region is wide enough to check it experimentally in available experimental setup. The detailed order-parameter structure of HQV characterized by ${A}_{1}$ core is given to facilitate the physical reasons of its stability over other vortices or textures.
