が構じられて・いた。In recent years, sintered metal friction plates have been used in various construction machinery and heavy equipment because they have higher heat resistance, absorb more energy, have a stable coefficient of friction, and have excellent wear resistance than other currently used friction plates. It is widely used in brake pads, clutches, etc. for vehicles, motorcycles, and various other general vehicles. Many of these sintered metal friction plates are controlled using hydraulic pressure such as hydraulic pressure. However, since the sintered metal friction material and the metal plate provided with the same have good thermal conductivity, there is a disadvantage that the temperature of the control oil and the like increases. To solve this problem, conventionally a heat insulating material was formed on the hydraulic pressure control surface of the sintered metal friction plate. As a method for forming this, methods such as bonding the heat insulating material to the hydraulic pressure control surface with an adhesive or fixing it with screws have been proposed.
