    • A pad spring located at the entrance side in the rotational direction of a disk is provided with guide plate portions, radially urging portions that urge a pair of friction pads radially outward of the disk, and circumferentially urging portions that urge the friction pads in the rotational direction of the disk. Each radially urging portion has a projection bent radially inward of the disk. Each guide plate portion has a space portion that allows the projection to abut against the radially inner wall surface of the associated pad guide when the radially urging portion is displaced radially inward of the disk so as to approach the guide plate portion. The circumferentially urging portions are wide plate-shaped members bent from the guide plate portions.

    • A cold forming tap with an internal finish cutting edge includes an external thread portion having radially outwardly protruding portions and relief portions which are alternately located in a helical direction in which an external thread extends. The protruding portions are forced into a surface of a prepared hole which has been previously formed through a workpiece, for thereby forming an internal thread on the surface. The improvement comprises: at least one of the protruding portions having a root diameter larger than that of the other of the protruding portions, the at least one of the protruding portions being removed down to a root of the external thread, and a flute being formed in a portion corresponding to the root of the at least one of the protruding portions, so as to provide the cutting edge in the portion corresponding to the root.
    • 具有内部精切削刃的冷成形丝锥包括具有径向向外突出部分和浮雕部分的外螺纹部分,所述外螺纹部分沿外螺纹延伸的螺旋方向交替设置。 突出部分被迫进入预先通过工件形成的预制孔的表面中,从而在表面上形成内螺纹。 该改进包括:突出部分中的至少一个具有比另一个突出部分的根部直径大的根部直径,至少一个突出部分被去除到外螺纹的根部,并且形成凹槽 在与所述至少一个所述突出部分的根部对应的部分中,以便在与所述根部对应的部分中设置所述切割刃。
