ても強度上何等問題はない。 Next, the operation of this embodiment will be explained. In FIG. 2, when pressure oil is supplied from a brake master cylinder (not shown) to each hydraulic cylinder 16, the first friction pad 111 is pressed against the operating piston 17, and the brake It comes into pressure contact with one side of the disc 1, and then due to the reaction force, the brake caliper 7
slides to the left along the sleeve 6, the second friction pad 112 comes into pressure contact with the other side of the brake disc 1, thus applying braking to the brake disc 1. In this case, since the first arm 9 2 side has a double structure with the back metal 13 2 , it has sufficient rigidity, and there is no problem in terms of strength even if the brake caliper 7 is configured in a split manner. .
また第２摩擦パツド１１2の裏金１３2は第１腕

ことができる。 Further, the backing metal 13 2 of the second friction pad 11 2 is integrated with the brake caliper 7 in close contact with the inner surface of the first arm portion 9 2 , so that the second friction pad 11 2 is closed during braking.
There is less vibration, and therefore braking noise can be reduced.
制動中に第２摩擦パツド１１2に発生する摩擦
熱は断熱材１８によりキヤリパ基部８側への伝導
を阻止されるので、断熱材１８はベーパロツク現
象防止手段として有効に機能する。 Since the frictional heat generated in the second friction pad 112 during braking is prevented from being conducted to the caliper base 8 side by the heat insulating material 18, the heat insulating material 18 effectively functions as means for preventing the vapor lock phenomenon.

に行うことができる。 When replacing the first and second friction pads 11 1 and 11 2 due to wear of the friction materials 12 1 and 12 2 , remove the lower support bolt 5 2 in FIG. 1 from the fixing bracket 4, and move the brake caliper 7 upward. Support bolt 5 1
If the second arm part 92 is separated from the caliper base 8 by rotating it clockwise in FIG.

動力を得ることができ、また第１、第２腕部９1，
９2のハンガピン挿通孔間の同軸度が問題になら
ないので加工性が良好となる。 When the first friction pad 11 2 is cantilever-supported by the pair of hanger pins 15 as described above, unlike the case where the hanger pin 15 is installed between the first and second arm portions 9 1 and 9 2 , each friction material 12 1 can be provided on almost the entire surface of the back metal 13 1 , a wide friction surface can be obtained and a large braking force can be obtained, and the first and second arm parts 9 1 ,
Since coaxiality between the 9 and 2 hanger pin insertion holes is not a problem, workability is improved.
さらに断熱材１８をキヤリパ基部８と第１腕部
９2間に挟着するので、その断熱材１８の取付け
に当り何等取付部材を必要としないといつた利点
がある。 Furthermore, since the heat insulator 18 is sandwiched between the caliper base 8 and the first arm 92 , there is an advantage that no attachment member is required for attaching the heat insulator 18.
なお、図示例においてはハンガピン１５を第１

に固着してもよい。 In addition, in the illustrated example, the hanger pin 15 is
Although it is screwed onto the arm 9 1 , the first arm portion 9 1 is press-fitted.
It may be attached to.

制動時における第２摩擦パツドの振動を少なくし
て制動鳴音を低減することができる。 As described above, according to the present invention, the second friction pad is integrated with the brake caliper by sandwiching its back metal between the caliper base and the second arm.
It is possible to reduce the vibration of the second friction pad during braking, thereby reducing braking noise.
またブレーキキヤリパは分割式に構成されてい
るので、一体型ブレーキキヤリパに比べて鋳型の
形状が単純となり、型代が安い等生産コストを安
価にし得る利点がある。 Further, since the brake caliper is constructed in a split type, the shape of the mold is simpler than that of an integrated brake caliper, which has the advantage of lower production costs such as lower mold costs.
