We introduce a model which incorporate the subdiffusive dynamics and the ratchet effect. Using a subordination ideology, we show that the resulting directed transport is sublinear, $<x(t)> \simeq Jt^{\beta}$, $\beta < 1$. The proposed model may be relevant to a phenomenon of saltatory microbiological motility.
