【0004】しかし、摩擦材を冷却水によって冷却する
といっても、冷却水への放熱は急激ではない為、ある程

Due to the increased thickness, heat transfer from the friction surface, which is pressed by the disc rotor of the friction material and generates a frictional force, to the pressing member is delayed. For this reason, the heat dissipation is deteriorated, and the temperature drop of the friction surface of the friction material is reduced.

The high thermal conductive material 3 and the pressing member 2 are conducted. The heat reaching the pressing member 2 is not rapidly dissipated by the cooling water, and the heat is accumulated in the friction material. However, the heat capacity between the friction surface 17 and the pressing member 2 is the same as the heat capacity of the high thermal conductive material 3. It is higher than the disc brake device without the conductive material 3. Therefore, the temperature rise of the friction material is low.
