を挾圧して制動を行つている。 A disk plate 1, which is made of a steel plate such as stainless steel, has an insertion hole 2 for an axle (not shown) in the center, a mounting surface 3 for a wheel hub (not shown) on its outer periphery, and A smooth pad sliding surface 4 is formed on the outer periphery of each pad, and a plurality of mounting holes 5 are formed on the mounting surface 3.Through these mounting holes 5, for example, a mounting bolt (not shown) or the like can be attached to a wheel hub of a motorcycle. A friction pad (not shown) is fixed to rotate together with the wheel by a fixing device, and is actuated by hydraulic pressure or the like.
It performs braking by squeezing the
そして本考案は前記取付面３に穿設される複数
の取付け孔５を不等間隔としたものである。 In the present invention, a plurality of mounting holes 5 formed in the mounting surface 3 are arranged at irregular intervals.
先ず第１図に示す実施例は、取付面３に形成す

夫々中心角θ1，θ2，θ3，θ4を隔てた位置に設けら
れる。 First, in the embodiment shown in FIG. 1, four mounting holes 5 formed in the mounting surface 3 are located at a radius R that is the same distance from the center C of the disk plate 1, and adjacent mounting holes 5, 5 are located at the same distance from the center C of the disk plate 1. They are provided at positions separated by central angles θ 1 , θ 2 , θ 3 , and θ 4 such that the central angles between them are different.
第２図に示す実施例は、４個の取付け孔５が、
相隣る取付け孔５，５の間の中心角が同一となる
ように中心角θを隔て、かつ中心Ｃからの距離が
異なるよう半径R1，R2，R3，R4の位置に設けら
れる。 In the embodiment shown in FIG. 2, the four mounting holes 5 are
Adjacent mounting holes 5, 5 are spaced apart by a center angle θ so that the center angles are the same, and are provided at radii R 1 , R 2 , R 3 , R 4 so that the distances from the center C are different. It will be done.
第３図に示す実施例は、４個の取付け孔５が、

異なる位置に設けられている。 In the embodiment shown in FIG. 3, the four mounting holes 5 are
The radii R 1 , R 2 , R 3 , R 4 and the central angles θ 1 , θ 2 , θ 3 are set so that the distance from the center C of the disk plate 1 and the central angle between adjacent mounting holes 5 and 5 are different. , θ 4 are provided at different positions.
従つて、制動時に摩擦パツドがパツド摺接面４

きる。 Therefore, during braking, the friction pad contacts the pad sliding surface 4.
Even if a plurality of vibrations are generated on the disk plate 1 using each mounting hole 5 as a node by applying pressure to the disc, the natural frequency of each vibration will be different because each mounting hole 5 is provided at unequal intervals, and this will cause the brake Brake squeal noise can be reduced by disturbing the resonance waveform of the squeal noise.
尚、以上の実施例においては、取付け孔５の数
を４個の場合について説明したが、４個に限定さ
れないことは言うまでもない。 In the above embodiment, the case where the number of attachment holes 5 is four has been described, but it goes without saying that the number is not limited to four.
