    • To be able to promote discharge of lubricating oil in a disengaged state while maintaining a large lining area to such an extent that it does not affect torque transmission capacity, heat resistance, and peeling resistance thereby to obtain an excellent effect to reduce a drag torque in a wide range of relative rotation speeds.In a segment friction material 1A as a wet friction material, drag torque reducing grooves 5A are provided only on top surfaces of part of segment pieces 3A among thirty pieces of segment pieces 3, 3A. A series of drag torque reducing grooves 5A extend over five segment pieces 3A along a direction almost at right angles to a straight line connecting a center point 5Aa thereof and a center O of a circumference. The series of drag torque reducing grooves 5A are provided at three places on the circumference. Thereby, discharge of ATF is promoted without reducing a lining area and an oil film is formed on the top surface of the segment piece 3A. Thus, a great effect to reduce a drag torque was obtained in a wide range of relative rotation speeds (500 rpm to 5000 rpm).

    • A friction material has a resin amount distribution that is the largest at a portion near a non-friction surface, that becomes lower toward an inside and that is the lowest at a portion near a friction surface. For example, such friction material is manufacture as follows. First, two friction materials are overlapped while the friction surfaces faced with each other. Then, the friction materials are dried at a room temperature. At this time, the resin has such a characteristic as to move while dragged by a solvent that dries from the non-friction surface located outside. Using such characteristic, the resin amount at the portion near the friction surface is lessened. Then, a temperature at the friction surface is made low and a temperature at the non-friction surface is made high in a drying step of the friction material. Thereby, the resin amount at the portion near the friction surface is lessened.
    • 摩擦材料的树脂量分布在非摩擦面附近的部分中最大,向内侧变小,在摩擦面附近的部分处最低。 例如,这样的摩擦材料制造如下。 首先,两个摩擦材料重叠,同时摩擦面相互面对。 然后,摩擦材料在室温下干燥。 此时,树脂具有在被位于外侧的非摩擦面干燥的溶剂的同时移动的特性。 使用这样的特性,摩擦面附近部分的树脂量减少。 然后,在摩擦材料的干燥步骤中,使摩擦面的温度变低,使非摩擦面的温度变高。 由此,摩擦面附近部分的树脂量减少。
