Abstract: A wet-type segmented friction material has a tape-like friction material substrate which is passed through and pressed between a roller having a dent at a center and a flat roller. At the same time, the friction material substrate is heated from an inside and an outside of the rollers so as to carry out a heat press compression processing. Then, a processed friction material substrate has a predetermined cross-section. The processed friction material substrate is cut into segment pieces each having a segment shape by a rotary push cutter having a sharp cutting edge. A cut position of the segment piece is selected such that two straight lines at two lateral sides of the segment shape is located within an area of a compressed portion of the processed friction material substrate. That is, a stepped or sunken compressed portion is provided on both sides of the segment piece.

Abstract: The side-under spoiler attaching structure for attaching the side-under spoilers to the right and left bottom portions of the vehicle body via the brackets employs a structure that; the bracket is formed in a rectangular-plate shape along the front-to-rear direction of the vehicle body; the two-sided tape is provided on the upper portion of the bracket, while a plurality of the supporting members for supporting the side-under spoiler is provided on the bottom portion of the bracket; and the side-under spoiler has a plurality of attaching members for engaging with the plurality of the supporting members of the bracket respectively.
