となった。In the conventional example shown in FIG.
Due to the action of the piston 3 inside, the butts 4 and 4 are used to apply forceful braking from both sides. Therefore, the heat of the brake disc 1 is transferred from the butt 4 and the piston 3 to the brake oil inside the caliper cylinder 2. The brake oil inside became bubbles, causing paper lock and reducing the braking action of the bat, jeopardizing safety.

した点に特徴がある。The present invention has been devised to overcome the difficulty of ridges, by providing a brake disc with a plurality of cooling holes passing through between one side and the other side thereof, and connecting these cooling holes to the axis of rotation of the disc. It is characterized in that the position of the hole on one side is inclined at a predetermined angle of rotation with respect to the hole on the other side.
次に、本発明の実施例について図面に沿って説明する。Next, embodiments of the present invention will be described with reference to the drawings.

ている。Even if the brake disc 1 is provided with cooling holes 5 parallel to the rotating shaft 1a, there is a certain degree of air cooling effect, but as shown in FIG.
The cooling holes 5 are appropriately sloped to facilitate blowing. That is, when the rotating shaft 1a rotates as shown by the arrow, an opening is provided at the outer peripheral edge of the left side surface (left side in FIG. 2) lb of the brake disc 1, and the right side IC is inclined toward the rotating shaft 1a. A cooling hole 5 is formed with a hole opening 5b.
この冷却孔5は、第3図に示したように、孔口5bに対

方向に位置させるように形成しである。As shown in FIG. 3, the cooling hole 5 is formed so that the hole 5a is positioned in the rotation direction of the brake disc 1 by a rotation angle θ relative to the hole 5b.

It is also possible to form cooling holes 5 similar to those described above that are inclined downward from the right side IC toward the right side IC.

It's Uruchino. Of course, the fins may be integrally formed within the cooling holes 5.

Alternatively, the cooling holes 5 may be inclined with some curve.

。According to the present invention, the brake disc 1 is provided with the cooling hole 5 that penetrates from one side to the other side, and the cooling hole 5 is inclined with respect to the rotational axis of the brake disc 1 and with respect to the hole opening 5b of the other side. Since the position of the hole opening 5a on one side is configured to have a predetermined rotation angle θ, air is drawn into the cooling hole 5 when the brake disc 1 rotates, and the air blows through with force. The cooling holes 5 have a large internal area that is exposed to air, which increases the cooling effect.
The amount of heat generated when the pads 4 are frequently tightened can be sufficiently dissipated, and the heating of the brake disc 1 prevents the brake oil from forming bubbles and prevents paper lock, and the braking operation is stable and sufficiently safe. You can maintain your sexuality. In particular, the cooling holes 5 configured as described above are advantageous because even if dirt, dust, etc. enter the holes, they have the function of discharging these obstacles. Furthermore, if fins are provided in the cooling holes 5, the heat dissipation area becomes larger, further increasing the safety of braking.
