To provide a fiber strand guiding part for guiding an untwisted fiber strand such as a lap or a sliver while keeping its width and diameter without disturbing the fiber arrangement of the fiber strand and preventing the adhesion of a foreign material such as a honeydew to the fiber strand guiding part.

A sliver table 16 has a guide surface 16a extending along the moving direction of slivers S, and the slivers S moving along the longitudinal direction of the sliver table 16 is blocked to prevent the movement toward the front end of the sliver table 16 by a wall 16b formed by bending an edge of the table upward. The contact of the slivers S with the guide plane 16a is inhibited by vibrating the sliver table 16 with a vibration means 20 placed under the sliver table 16 and generating a sound pressure. A plurality of vibrators 21 constituting the vibration means 20 are arranged along the longitudinal direction of the sliver table 16.
