る。 The assembly of the core bar 7 and facing 8 described above is manufactured as follows. First, materials for the facing 8 are placed on both sides of the core bar 7. This facing material is an organic material that can be pressure molded, and for example, a material similar to conventional materials such as asbestos bonded with a rubber or plastic binder is used. Next, as shown in FIG. 3, pressure is applied to the facing material from both sides in a heated state using a pair of molds 22 and 23.
Form the facing 8. In this forming step, a portion of the facing 8 enters the connecting hole 18 and the slit 14 to form connecting portions 19 and 20.

両側のフエーシング部分の厚さが均一になる。 Projections 25 are provided on the molding surfaces of the molds 22 and 23, and depressions 27 are formed in the surface of the core metal 7 by the projections 25. This depression 27 extends generally in the radial direction along the slit 14, as shown in FIG. The recesses 27 are wider than the slits 14 and are aligned in the axial direction with respect to the slits 14 and the side edges 29 of the support portions 13 on both sides thereof (slits 1
4 and side edges 29). Since the dimensions and shape of the protrusion 25 correspond to the recesses 27, the protrusion 25 does not fit into the side edge 29 of the support portion 13 during the above molding.
, sandwich the thin facing part and press from both sides. As a result, the support portion 13 is positioned at the axially intermediate portion of the entire facing 8, and the facing portions on both sides of the core bar 7 have a uniform thickness over the entire facing 8 that has been formed.

性を高めることができる。(Effects of the Invention) As explained above, according to the present invention, when forming the facing 8 with the core bar 7 sandwiched therebetween, the forming mold protrusion 25 forms the depression 27 on the facing surface.
Since the core metal 7 is positioned in the axially intermediate portion of the entire facing 8, the core metal 7 can be prevented from being misaligned due to thermal strain. Further, since the radial slits 14 are provided in the core metal 7, thermal distortion of the core metal 7 can be effectively released from the side edges 29. Therefore, the position of the core metal 7 can be set extremely accurately, the thickness of the facing portions on both sides of the core metal 7 can be made uniform, and the durability of the facing 8 can be increased.
