Abstract

A top front roller (20) includes a fiber-contacting portion (30) formed with a substantially uniform diameter and adapted to make a fiber bundle to contact with an outer peripheral surface thereof, and a reduced-diameter portion (31) having a diameter shorter than the fiber-contacting portion (30) at both ends of the fiber-contacting portion in an axial direction. A total width of the fiber-contacting portion (30) and the reduced-diameter portion (31) in the axial direction is 30 mm or longer and 34 mm or shorter, and a width of the fiber-contacting portion (30) in the axial direction is less than 18 mm.
