A pressure roller is generally disposed between the yarn discharge portion of a spinning unit and a yarn oscillating device of a winding unit in a spinning unit. The pressure roller is in contact with a drive roller to form a nip therebetween and is formed with a notch provided in one end edge of the pressure roller to transport the yarn into the nip. The notch intersects the end face of the pressure roller at boundary lines extending from the end edge thereof inwardly. According to this invention, one of the boundary lines provided on the downstream side of a rotational direction of the pressure roller comprises at least two portions extending out of line, and distances between tangential planes to the two portions of the one of the boundary lines and planes parallel to the tangential planes and including a center of the pressure roller are so selected that the distance with respect to the portion including the outermost end of the one of the boundary lines is larger than that with respect to the portion including the innermost end of the one of the boundary lines.
