又、上述の様な構成を有する回入側、回出側各補強ブリッジ部１２ａ、１２ｂ、１３ａ、１３ｂを設ける事により、前記開口部１０のうちの４つの隅角部に、これら回入側、回出側各補強ブリッジ部１２ａ、１２ｂ、１３ａ、１３ｂにより他の部分（内側部分）と分割された、略台形状の隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを形成している。そして、これら隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを通じて、前記回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂを径方向外方に露出させている。更に、前記回入側、回出側各補強ブリッジ部１２ａ、１２ｂ、１３ａ、１３ｂの径方向厚さ寸法や径方向に関する配置位置等を調節する事により、前記各隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを、径方向だけでなく、軸方向に開口させると共に、周方向にも開口させている。
In addition, by providing the reinforcing bridge portions 12a, 12b, 13a, 13b having the above-described configuration, the four entrance corners of the opening 10 are provided on the entrance side. The trapezoidal corner openings 29a, 29b, 29c, and 29d are formed by being divided from the other portions (inner portions) by the reinforcing-side reinforcing bridge portions 12a, 12b, 13a, and 13b. And these corner openings 29a, 29 b, 29c, through 29d, the times the entry side, the run-out side the torque receiving surfaces 19a, 19b, 20a, is exposed to 20b radially outward. Further, by adjusting the radial thickness dimension and the radial position of the reinforcing bridge portions 12a, 12b, 13a, 13b on the entrance side and the exit side, the respective corner opening portions 29a, 29b, 29c and 29d are opened not only in the radial direction but also in the axial direction and also in the circumferential direction.
又、本例の場合には、上述の様に剛性を向上させられる分、前記回入側、回出側両連結部８、９の周方向に関する幅寸法を短くして（開口部１０の周方向に関する幅寸法を長くして）、前記開口部１０のうちの隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを通じて、前記回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂを径方向外方に露出させている。この為、これら各隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを通じて、前記回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂを直接冷却する（冷却風を直接導く）事ができる。従って、この面からも前記キャリパ２の温度上昇を効果的に抑える事ができる。
Further, in the case of this example, the width dimension in the circumferential direction of the turn-in side and turn-out side connecting portions 8 and 9 is shortened by the amount that the rigidity is improved as described above (the circumference of the opening 10). by lengthening the width dimensions for direction), the corner openings 29a of the opening 10, 29 b, 29c, through 29d, the times the entry side, the run-out side the torque receiving surfaces 19a, 19b, 20a, and 20b Exposed radially outward. Therefore, each of these corner openings 29a, 29 b, 29c, through 29d, the times the entry side, the run-out side the torque receiving surfaces 19a, 19b, 20a, 20b directly cooled (directing cooling air directly) it is it can. Therefore, also from this aspect, the temperature rise of the caliper 2 can be effectively suppressed.
又、前記各隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを通じて、例えばエンドミル等の切削工具や研削工具等を、径方向外方から挿入する事により、前記キャリパ２の径方向外方から前記回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂの加工を行う事が可能になる。更に、前記回入側、回出側各補強ブリッジ部１２ａ、１２ｂ、１３ａ、１３ｂの周方向外端部を、前記回入側、回出側各中継部２７、２８を介して前記回入側、回出側各連結部８、９に接続している為、前記隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄのうちで、軸方向に関してロータ１４側（キャリパ２の中央側）に存在する部分の周方向長さ寸法を、前記回入側、回出側各中継部２７、２８を設けない場合に比べて大きくできる。この為、前記隅角開口部２９ａ、２９ｂ、２９ｃ、２９ｄを通じて前記回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂを加工する際に、これら回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂのうちで、軸方向に関してロータ１４側に存在する部分の加工性を向上する事ができる。
Further, by inserting a cutting tool such as an end mill or a grinding tool from the outside in the radial direction through each corner opening 29a, 29b, 29c, 29d, the rotation from the outside in the radial direction of the caliper 2 is performed. the entry side, the run-out side the torque receiving surfaces 19a, 19b, 20a, it becomes possible to perform processing of 20b. Further, the circumferential outer end portions of the reinforcing bridge portions 12a, 12b, 13a, and 13b on the return side and return side are connected to the return side via the relay portions 27 and 28 on the return side and return side, respectively. In the corner openings 29a, 29b, 29c, and 29d, the portions that are present on the rotor 14 side (center side of the caliper 2) in the axial direction are connected to the connecting portions 8 and 9 on the delivery side. The length in the circumferential direction can be made larger than that in the case where the relay parts 27 and 28 are not provided. Therefore, the corner openings 29a, 29 b, 29c, the rotary inlet side through 29d, the run-out side the torque receiving surfaces 19a, 19b, 20a, when processing 20b, these rotation entrance side, the run-out side the torque receiving surfaces 19a, 19b, 20a, among 20b, can be improved portion of workability present in the rotor 14 side in the axial direction.
又、前記回入側、回出側各補強ブリッジ部１２ａ、１２ｂ、１３ａ、１３ｂの径方向内側面を利用して、前記各プレッシャプレート１８、２５の周方向端部と前記回入側、回出側各トルク受面１９ａ、１９ｂ、２０ａ、２０ｂとの間部分に配置した前記各パッドクリップ５ａ、５ｂを弾性的に支持する事ができる。この為、これら各パッドクリップ５ａ、５ｂを設けた事による、前記インナ、アウタ両パッド３、４の挙動の安定化を図る事ができる
Further, by using the radially inner side surfaces of the reinforcing bridge portions 12a, 12b, 13a, and 13b on the entrance side and the exit side, the circumferential end portions of the pressure plates 18 and 25, the entrance side, outlet side each torque receiving surfaces 19a, 19b, 20a, the disposed between the portion of the 20b each pad clip 5a, can be supported 5b elastically. For this reason, it is possible to stabilize the behavior of the inner and outer pads 3 and 4 by providing these pad clips 5a and 5b.

[Second Example of Embodiment]
A second example of the embodiment of the present invention will be described with reference to FIGS. This example shows a case where the present invention is applied to a floating disc brake device 1a.
In the case of this example, the inner side and outer side pads 3a and 4a are formed in the locking recesses 50 and 50 of the turn-in side and turn-out side engaging portions 48 and 498 provided at both ends in the circumferential direction of the support 47, respectively. By engaging engagement protrusions 51 provided at both ends in the circumferential direction of the pressure plates 18a and 25a, the front inner side and outer side pads 3a and 4a are supported so as to be capable of axial displacement. Also, the between the engaging recesses 50 and 50 and the respective engaging projection piece 51, is interposed pad clip 5c, the 5d.
以上の様な構成を有する本例の場合にも、前記インナ側、アウタ側各周方向冷却孔３２ｃ、３３ｃを通じて、前記各プレッシャプレート１８ａ、２５ａの周方向両端部に向け風を直接導く（送り込む）事ができ、伝熱部であるこれら各プレッシャプレート１８ａ、２５ａの周方向両端部を効率良く冷却できる。又、前記インナ側、アウタ側各周方向冷却孔３２ｃ、３３ｃの内側を風が通過する事で、前記サポート４７のうち、前記各プレッシャプレート１８ａ、２５ａから熱が伝わる部分（係止凹部５０の内面）を効果的に冷却できる。この結果、本例のディスクブレーキ装置１ａによれば、前記各プレッシャプレート１８ａ、２５ａから前記サポート４７に対して、制動時に発生した熱が伝わる事を有効に防止でき、このサポート４７が高温になる事を有効に防止できる。
その他の構成及び作用効果に就いては、前記実施の形態の第１例の場合とほぼ同様である。
Also in the case of this example having the above-described configuration, the wind is directly guided (sent into) the circumferential end portions of the pressure plates 18a and 25a through the inner and outer circumferential cooling holes 32c and 33c. And can cool both ends in the circumferential direction of each of the pressure plates 18a and 25a, which are heat transfer portions, efficiently. Further, the inner side, by the outer side each circumferential cooling hole 32c, and inner 33c wind passes, among the support 47, of the respective pressure plate 18a, heat is transferred portions from 25a (engaging recess 50 The inner surface) can be effectively cooled. As a result, according to the disc brake device 1a of this example, it is possible to effectively prevent the heat generated during braking from being transmitted from the pressure plates 18a and 25a to the support 47, and the support 47 becomes high temperature. Things can be effectively prevented.
Other configurations and operational effects are substantially the same as those in the first example of the embodiment.
