Description of the Related Art As friction materials for automobiles and motorcycles, such as brake plates and clutch plates, metal pads, semi-metal pads, carbon metal pads, etc. are used instead of asbestos, which has been pointed out to be harmful in recent years. However, as a method of joining metal members such as joining these friction materials to brake plates and clutch plates,
Brazing methods are known. In this brazing method, a brazing material such as a metal or an alloy having a melting point lower than those of the two members intended to be joined (members to be joined) is sandwiched, and then the brazing material is sintered. Is a method of joining the members to be joined.

増えコストも増大するという問題がある。In the above brazing method, the brazing material may be in the form of foil, powder or the like. When a brazing material in the form of foil is used, when the brazing material is sandwiched between the members to be joined, Since the members to be joined and the brazing material are not fixed, there is a problem that a position shift occurs between the members to be joined due to vibration or impact before the brazing material is sintered or the brazing material falls off. On the other hand, when a powdered brazing material is used, it is usually kneaded with a resin to form a paste or mixed with castor oil to form a liquid, which is applied to the members to be joined, but is applied to a uniform thickness. That is, it is difficult to make the shape to follow the shape of the members to be joined. There is also a method of plating a brazing material on the surfaces of the members to be joined, but this has a problem that the number of steps increases and the cost also increases.

This method is intended to prevent the positional displacement between the members to be joined and the falling off of the brazing material by the adhesive, and to perform the brazing easily.

Since the material is used, it is suppressed that the resin component remains in the joining material during sintering of the brazing material and inhibits the metal bonding of the brazing material. Therefore, the adhesive strength after sintering is improved.
