The hydraulic fluid supplied to the hydraulic pressure chamber 16 pushes the piston 13 in the direction of the disk rotor 2 so that the friction pad 11 on the action portion side slides on one side surface of the disk rotor 2, and then the caliper body 10 acts. The reaction force claw 10f causes the friction pad 11 on the reaction portion side to slidably contact the other side surface of the disc rotor 2 to perform a braking action.

この時、各摩擦パッド１１はディスク回出側に引き摺られ、裏板１１ｂのディスク回出側面１１ｆとスライドピン支持部１０ｄのトルク受面１０ｋとが当接する。これにより、制動トルクは、トルク受面１０ｋからスライドピン支持部１０ｄへ、該スライドピン支持部１０ｄからスライドピン本体８ａへ、該スライドピン本体８ａから六角ボルト８ｂへ、該六角ボルト８ｂからスライドピン取付部５へ、該スライドピン取付部５から第１支持脚４ａ，第２支持脚４ｂ，第３支持脚４ｃを介してフロントフォーク３へと伝達され、部品点数を増やすことなく、フロントフォーク３で制動トルクを良好に受けることがき、キャリパボディ１０の支持剛性を確保することができる。特に、第１支持脚４ａは、制動トルクの作用方向に延設され、また、第１支持脚４ａと直交する方向に第２支持脚４ｂを設けたことにより、制動トルクをフロントフォーク３でより確実に受けることができる。また、スライドピン８は、第１フランジ部８ｄと第２フランジ部８ｈとで、スライドピン取付部７を挟持し、スライドピン本体８ａと六角ボルト８ｂとを連結固定することから、両フランジ部８ｄ，８ｈでスライドピンの倒れを防止し、制動トルクが掛かってもキャリパボディ１０のスライド性を確保することができる。   At this time, each friction pad 11 is dragged toward the disk delivery side, and the disk delivery side surface 11f of the back plate 11b and the torque receiving surface 10k of the slide pin support portion 10d abut against each other. Thus, the braking torque is generated from the torque receiving surface 10k to the slide pin support portion 10d, from the slide pin support portion 10d to the slide pin main body 8a, from the slide pin main body 8a to the hexagon bolt 8b, and from the hexagon bolt 8b to the slide pin. The front fork 3 is transmitted from the slide pin mounting portion 5 to the front fork 3 through the first support leg 4a, the second support leg 4b, and the third support leg 4c without increasing the number of parts. Thus, the braking torque can be satisfactorily received, and the support rigidity of the caliper body 10 can be ensured. In particular, the first support leg 4a is extended in the direction in which the braking torque is applied, and the second support leg 4b is provided in a direction orthogonal to the first support leg 4a, so that the braking torque can be increased by the front fork 3. I can receive it reliably. Further, since the slide pin 8 sandwiches the slide pin mounting portion 7 between the first flange portion 8d and the second flange portion 8h and connects and fixes the slide pin main body 8a and the hexagon bolt 8b, both flange portions 8d. 8h, the slide pin can be prevented from collapsing, and the sliding performance of the caliper body 10 can be ensured even when braking torque is applied.

さらに、スライドピン取付部５，６は、各支持脚４ａ，４ｂ，４ｃ，６ａ，６ｂとを介して、フロントフォーク３の中心軸よりも反ディスクロータ側にそれぞれ突設されていることから、車輪と当接しない範囲で、キャリパボディ１０の大きさを確保でき、充分な制動力を得ることができる。また、トルクを伝達する第１支持脚４ａ，第２支持脚４ｂ，第３支持脚４ｃとフロントフォーク３との接合面積を大きくすることができ、第１支持脚４ａ，第２支持脚４ｂ，第３支持脚４ｃを介して、制動トルクを良好にフロントフォークに伝達させることができる。さらに、スライドピン取付部５，６は、支持脚を介してそれぞれフロントフォーク３に連結されることから、従来の板状のブラケットを用いるものに比べて、軽量化を図ることができる。また、各スライドピン８，９は、スライドピン本体８ａ，６ａの雌ねじ孔８ｅ，９ｅに、六角ボルト８ｂ，９ｂの雄ねじ部８ｉ，９ｉをそれぞれねじ込むだけで、スライドピン取付部５，７に取り付けることができ、簡単な構造で確実に各スライドピン８，９の取り付けを行うことができる。   Furthermore, since the slide pin mounting portions 5 and 6 are respectively projected from the center axis of the front fork 3 to the side opposite to the disc rotor via the support legs 4a, 4b, 4c, 6a and 6b. The size of the caliper body 10 can be ensured within a range that does not contact the wheel, and a sufficient braking force can be obtained. Further, the joint area between the first support leg 4a, the second support leg 4b, the third support leg 4c and the front fork 3 for transmitting torque can be increased, and the first support leg 4a, the second support leg 4b, The braking torque can be satisfactorily transmitted to the front fork via the third support leg 4c. Further, since the slide pin mounting portions 5 and 6 are respectively connected to the front fork 3 via the support legs, the weight can be reduced as compared with the conventional one using a plate-like bracket. The slide pins 8 and 9 are attached to the slide pin attachment portions 5 and 7 simply by screwing the male screw portions 8i and 9i of the hexagon bolts 8b and 9b into the female screw holes 8e and 9e of the slide pin bodies 8a and 6a, respectively. Thus, the slide pins 8 and 9 can be securely attached with a simple structure.

図５は本発明の第２形態例を示すもので、上述の形態例と同様の構成要素を示すものには、同一の符号を付してその詳細な説明は省略する。本形態例の六角ボルト８ｂの雄ねじ部８ｋは、軸方向の長さ寸法が短く形成され先端部のみに設けられており、六角ボルト８ｂをスライドピン取付部５の反ディスクロータ側から挿入し、該スライドピン取付部５から突出した雄ねじ部８ｋをスライドピン本体８ａの雌ねじ孔８ｅにねじ込んで、第１フランジ部８ｄと第２フランジ部８ｈとでスライドピン取付部５を挟持した際に、雌ねじ孔８ｅと雄ねじ部８ｋとが第１フランジ部８ｄよりもスライドピン本体８ａの奥部側で螺合する。   FIG. 5 shows a second embodiment of the present invention. Components that are the same as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The male screw portion 8k of the hexagon bolt 8b of this embodiment is formed with a short axial length and is provided only at the tip portion, and the hexagon bolt 8b is inserted from the side opposite to the disk rotor of the slide pin mounting portion 5; When the male screw portion 8k protruding from the slide pin mounting portion 5 is screwed into the female screw hole 8e of the slide pin main body 8a and the slide pin mounting portion 5 is sandwiched between the first flange portion 8d and the second flange portion 8h, the female screw The hole 8e and the male screw portion 8k are screwed together on the deeper side of the slide pin main body 8a than the first flange portion 8d.

これにより、制動時に剪断力の掛かる第１フランジ部８ｄとスライドピン取付部５との連結部分近傍には、雄ねじを切っていない六角ボルト８ｂの軸部８ｇが配置されることから、スライドピン８とスライドピン取付部５との連結強度を確保することができる。   Accordingly, the shaft portion 8g of the hexagon bolt 8b that is not cut off by the male screw is disposed in the vicinity of the connecting portion between the first flange portion 8d to which the shearing force is applied at the time of braking and the slide pin mounting portion 5, so that the slide pin 8 And the connecting strength between the slide pin mounting portion 5 can be ensured.

本形態例では、ディスク回出側のスライドピン８の構造のみを挙げて説明したが、ディスク内周側のスライドピン９を同様の構造とすることもできる。   In the present embodiment, only the structure of the slide pin 8 on the disk delivery side has been described. However, the slide pin 9 on the inner periphery side of the disk may have the same structure.

なお、本発明は上述の形態例のように、ディスク回出側のスライドピン取付部の支持脚を３本設けるものに限らず、支持脚は何本設けてもよく、略三角形状に広がった１本の板形状の支持脚を設けるものであってもよい。また、スライドピンは、スライドピン本体に雄ねじ部を設け、該スライドピン本体をスライドピン取付部のディスクロータ側から挿入し、雄ねじ部をスライドピン取付部の反ディスクロータ側に突出させるとともに、第２フランジ部を備えたスリーブナットを固定部材として用い、該スリーブナットを雄ねじ部に螺着して、スライドピン本体の第１フランジ部とスリーブナットの第２フランジ部とでスライドピン取付部を挟着して連結固定するようにしてもよい。   Note that the present invention is not limited to providing three support legs for the slide pin mounting portion on the disk delivery side as in the above-described embodiment, and any number of support legs may be provided, and the support legs spread in a substantially triangular shape. One plate-shaped support leg may be provided.
