As shown in Fig. 1, the friction plate r of a conventional wet type disc brake has internal teeth 1a in the center for spline fitting to the inner hub of the disc brake.
A heat-resistant and oil-resistant rubber-based friction material 2 is applied to the outer peripheral portion 1c, which is the sliding contact portion of the friction plate annular substrate 1 made of an iron plate or the like. The outer peripheral edge 1d is covered and bonded under heat and pressure to form a convex annular shape, and at the same time 1
The next step was vulcanization. Therefore, the burr B protrudes from the inner peripheral edge 2a of the friction material 2, and after the secondary vulcanization is completed,
This burr B had to be removed. The work of removing this burr B not only requires a lot of effort but also is difficult to finish neatly. Further, when used under severe conditions, the friction material may easily peel off, especially from the inner peripheral edge side.

る。 That is, the gist of the present invention is to cover the outer circumferential sliding contact portion and the outer peripheral edge of an annular substrate for a friction plate made of an iron plate or the like with a friction material made of heat-resistant and oil-resistant rubber. In a friction plate of a wet type disc brake, which is formed into a convex annular shape by heat-pressing bonding to the outer circumferential edge thereof, a long hole corresponding to the inner circumferential edge of the friction material formed into the convex annular shape is formed in the friction plate annular substrate. A plurality of holes are formed in the annular substrate for the friction plate, and in the outer peripheral sliding contact portion sandwiched between the outer peripheral edge of the annular substrate for the friction plate and the long hole, the entire cross-sectional circumference including the inner peripheral edge formed by the long hole is continuous with the friction material. The friction plate of a wet type disc brake is characterized by being encapsulated in a wet type disc brake.

に限られるものではない。 In FIGS. 2a and 2b, 11b is a central hole having internal teeth 11a, and a heat-resistant and oil-resistant rubber-based friction material 12 is bonded by heat and pressure to the outer peripheral part 11c, which is the sliding contact part of the annular substrate 11 for the friction plate. , which covers the outer peripheral edge 11d of the substrate 11 and is formed in a convex annular shape. At this time, arcuate elongated holes 11e and 11 occupy most of the connecting portions 11f corresponding to the inner peripheral edge 12a of the friction material 12 formed on the substrate 11, leaving a connecting portion 11f.
A plurality of holes e... are drilled in advance, and the outer peripheral edge 11d of the substrate 11 and the arcuate long holes 11e, 11e
The entire cross-sectional circumference of the outer circumferential portion 11c' sandwiched between the two is covered with the friction material 12. Incidentally, the number of the arcuate long holes 11e, 11e, . . . is not limited to four as shown in the figure.

In this way, in the friction plate R of the present invention, the substrate 1
Both sides and the outer peripheral edge of the outer circumferential portion 11c of 1 are covered with a friction material 12, and the outer circumferential portion 11c' that occupies most of the outer circumferential portion 11c corresponds to the arc-shaped elongated hole 11e, and this elongated hole 11e is formed. Since the entire cross-sectional circumference, including the inner peripheral edge, is continuously and completely covered with the friction material 12, the adhesive strength of the friction material 12 increases, and there is no fear that the friction material will peel off even under severe conditions. In addition, it is only necessary to perform deburring on the portion corresponding to the connecting portion 11f, making the finishing work very simple, thereby providing an extremely useful friction material for wet disc brakes.
