PROBLEM TO BE SOLVED: To provide a routing guide for a bulk material that is equipped with a simple driving part with reliable motion. SOLUTION: This routing guide for the bulk material has a housing comprising an inlet channel 4, at least two outlet channels 5, 6, and a first cavity 10 having a first given width in the axial direction. Furthermore, a stopper 11, having a second given width in the axial direction, is arranged rotatably centered on a rotary axis in the first cavity in order to connect the inlet channel to one of the outlet channels selectively. A driving force to rotate the stopper is given by a hydraulic actuator structure that includes at least a second cavity 19 in the housing having a rotary piston 15'. As being a rotation centered on the axis, the rotary piston has at least one moving face 16a' or 16b' applied a bias by fluid in the second cavity.
