A first liquid passage hole 12 is formed toward the fluid pressure chamber 8 on the disk delivery side of the one action part 3a from the other action part 3a. The through hole 12 and the second liquid through hole 13 intersect each other, a bleeder hole 14 is formed on the opening side of the second liquid through hole 13, and a bleeder screw 15 is screwed into the bleeder hole 14. The opening of the first liquid passage hole 12 is sealed with a sealing plug 16.

一方の作用部３ａには、ユニオン孔１７が形成される。該ユニオン孔１７は、一端部が作動液連通孔１１に開口し、他端部が前記一方の作用部３ａのディスク周方向中央部の天井面に開口し、他端部には、ユニオンボルト（図示せず）が螺着される。   A union hole 17 is formed in one action part 3a. The union hole 17 has one end opened to the hydraulic fluid communication hole 11, the other end opened to the ceiling surface at the center in the disk circumferential direction of the one action part 3 a, and a union bolt ( (Not shown) is screwed.

このようなキャリパボディ３は、鋳造によって製造され、各作用部３ａに併設されるシリンダ孔４，４と、該シリンダ孔４，４間に形成される作動液連通孔１１とは、１つのシェル中子によって形成される。シェル中子は周知のもので、例えば、中子成形用の金型内にシェル砂を吹き込んで焼成した後、金型内から取り出すことにより得られる。キャリパボディ鋳造後、型ばらしを行う際に、シェル中子は周知の砂除去装置を用いてシェル砂が除去され、シリンダ孔４，４には、所定の仕上げ加工が施される。なお、ユニオン孔１７は、一方の作用部３ａのディスク周方向中央部の天井面から、作動液連通孔１１に向けて穿設された穿設孔であって、該穿設孔の天井面側の開口部に、ユニオンボルトを螺着するための雌ねじ孔１７ａを含む。   Such a caliper body 3 is manufactured by casting, and the cylinder holes 4 and 4 provided to the respective action portions 3a and the hydraulic fluid communication hole 11 formed between the cylinder holes 4 and 4 are formed as one shell. Formed by the core. The shell core is a well-known one, and can be obtained, for example, by blowing shell sand into a core molding die and firing it, and then removing it from the die. When mold release is performed after caliper body casting, shell sand is removed from the shell core using a known sand removal device, and the cylinder holes 4 and 4 are subjected to predetermined finishing. The union hole 17 is a perforation hole that is perforated from the ceiling surface at the central portion in the disk circumferential direction of the one action portion 3a toward the hydraulic fluid communication hole 11, and is on the ceiling surface side of the perforation hole.

Further, the union hole 17 is formed by drilling from the ceiling surface at the central portion in the disk circumferential direction of the one working portion 3a toward the hydraulic fluid communication hole 11, and the inner end of the union hole 17 is which of the hydraulic fluid communication holes 11 Since the hole may be opened at a position, it is not necessary to drill the union hole 17 with high accuracy, and the time and labor required for processing the union hole 17 can be omitted, thereby improving workability. . Moreover, the union hole 17 can be pierced in a stable state by piercing from the ceiling surface in the central portion of the disk circumferential direction of the one action portion 3a. Further, since the bleeder hole 14 is formed by utilizing the opening side of the second liquid passage hole 13, it can be easily formed, and is disposed above when the caliper body 3 is attached to the vehicle body. Therefore, it is possible to perform air bleeding well.

なお、上述の形態例では、穿設孔をユニオン孔としているが、同様に作動液連通孔に向けて作用部の外面から穿孔した穿設孔をブリーダ孔とすることもできる。また、本発明に用いられる中子は、シェル中子に限らず、金属製の中子を適用することもできる。さらに、本発明は上述の形態例のように、ラジアルマウントタイプのキャリパボディに用いられるものに限らず、一方の作用部に一対の車体取付腕を突設し、該車体取付腕に挿通するディスク軸方向の取付ボルトを車体に螺着させてキャリパボディを車体に取り付けるものでも良い。また、６ポット以上の対向型のキャリパボディにも適用することができ、ポット数に応じて、前記ユニオン孔は、一方の作用部の天井面の任意の位置に形成すれば良く、さらに、一方の作用部の天井面以外の作用部外面に形成するものでも良い。さらに、本発明は、２輪車のディスクブレーキのキャリパボディに限らず、３輪車や４輪車用のディスクブレーキのキャリパボディにも適用することができる。   In the above-described embodiment, the perforation hole is a union hole. Similarly, the perforation hole that is perforated from the outer surface of the action portion toward the hydraulic fluid communication hole may be a bleeder hole. The core used in the present invention is not limited to a shell core, and a metal core can also be applied. Further, the present invention is not limited to the one used in the radial mount type caliper body as in the above-described embodiment, and a disk in which a pair of vehicle body mounting arms protrudes from one working portion and is inserted into the vehicle body mounting arm. A caliper body may be attached to the vehicle body by screwing axial mounting bolts onto the vehicle body. It can also be applied to an opposing caliper body of 6 pots or more, and the union hole may be formed at an arbitrary position on the ceiling surface of one working portion according to the number of pots. It may be formed on the outer surface of the action part other than the ceiling surface of the action part.
