We theoretically study the spin Hall effect in a simple tight-binding model of stacked-kagome Weyl semimetal Co3Sn2S2 with ferromagnetic ordering. We focus on the two types of the spin Hall current: one flowing in the in-plane direction with respect to the kagome lattice (in-plane spin Hall current), and one flowing in the stacking direction (out-of-plane spin Hall current). We show the spin Hall conductivities for those spin currents drastically change depending on the direction of the magnetic moment. Especially, the out-of-plane spin Hall current may induce surface spin accumulation, which are useful for the perpendicular magnetization switching via spin-orbit torque.
