Abstract: Let $ \Gamma$ be a $ 3$-dimensional Kleinian punctured torus group with accidental parabolic transformations. The deformation space of $ \Gamma$ in the group of Möbius transformations on the $ 2$-sphere is well known as the Maskit slice $ {\mathcal{M}}_{1,1}$ of punctured torus groups. In this paper, we study deformations $ \Gamma'$ of $ \Gamma$ in the group of Möbius transformations on the $ 3$-sphere such that $ \Gamma'$ does not contain screw parabolic transformations. We will show that the space of the deformations is realized as a domain of $ 3$-space $ \mathbb{R}^3$, which contains the Maskit slice $ {\mathcal{M}}_{1,1}$ as a slice through a plane. Furthermore, we will show that the space also contains the Maskit slice $ \mathcal{M}_{0,4}$ of fourth-punctured sphere groups as a slice through another plane. Some of the other slices of the space will be also studied.
