Summary:PROBLEM TO BE SOLVED: To provide a disc brake device for operating a brake constantly for a specific response time regardless of an abrasion amount of a pad.SOLUTION: A disc brake device includes a spindle 13 mounted in a state that it is axially movable to a sleeve member 22 and they cannot be relatively rotated, a wedge cam 20 mounted in a state that it is axially movable to the sleeve member 22 and they cannot be relatively rotated, a rotating member 38 disposed between the spindle 13 and the wedge cam 20, engaged with a one-way reversible screw of the spindle 13, frictionally engaged by elastically energized in a direction to press a friction face to a contact face of the wedge cam 20, and released from the wedge cam 20 and rotated when the spindle 13 is moved by a prescribed stroke or more in a driving direction and returned, and an adjustment member 23 frictionally held to the sleeve member 22 by a friction member 24. The adjustment member 23 holds a cam rod 21 axially movably in a prescribed stroke.SELECTED DRAWING: Figure 3 【課題】パッド摩耗量に係わらず常に一定の応答時間でブレーキを作動させるためのディスクブレーキ装置を提供する。【解決手段】スリーブ部材２２に対して軸方向に移動可能かつ相対回転不能に取り付けられるスピンドル１３と、スリーブ部材２２に対して軸方向に移動可能かつ相対回転不能に取り付けられるウェッジカム２０と、スピンドル１３とウェッジカム２０との間に介装され、スピンドル１３の一方向可逆ねじに螺合するとともに、ウェッジカム２０の接触面に摩擦面が押付けられる方向に弾性付勢されて摩擦係合し、スピンドル１３が駆動方向に所定のストローク以上移動して戻る時に、ウェッジカム２０から開放されて回転する回転部材３８と、スリーブ部材２２に対してフリクション部材２４によって摩擦保持される調整部材２３と、を備え、調整部材２３が、軸方向に所定のストローク内移動自在にカムロッド２１を保持する。【選択図】図３
