A spin structure on a closed surface S of genus g≥2 is a covering of the unit tangent bundle of S witch restricts to a standard covering of the fiber. Such a spin structure has a parity, even or add. The spin mapping class is the stabilizer of such a spin structure in the mapping class group of S. We use a subgraph of the curve graph to construct an explicit generating set of the spin mapping class group consisting of Dehn twists about a system of 2g−1 simple closed curves.
