To provide a disc brake for improving responsiveness while securing a brake force.SOLUTION: A rotation linear conversion mechanism 32 of a disc brake 1a comprises: an input rod 35 to which rotation from an electric motor 30 is transmitted; a cylindrical output member 36 arranged outside the input rod 35 in a radial direction, movably in an axial direction and relatively non-rotatably supported with respect to a caliper main body 6, and imparting thrust to a piston 15; a plurality of planetary rods 37 which are arranged between the input rod 35 and the cylindrical output member 36 at an interval along a peripheral direction, and engaged with the input rod 35 and the cylindrical output member 36; and a coil spring 39 arranged between the planetary rod groups 37 ... and the cylindrical output member 36, and imparting an energization force to the relative rotation of the cylindrical output member 36 and the planetary rod groups 37 ... This constitution can improve responsiveness while securing a brake force.SELECTED DRAWING: Figure 1 【課題】制動力を確保しつつ、応答性を向上させるディスクブレーキを提供する。【解決手段】ディスクブレーキ１ａの回転直動変換機構３２は、電動モータ３０からの回転が伝達される入力ロッド３５と、該入力ロッド３５の径方向外方に配置され、キャリパ本体６に対して、軸方向に移動自在、且つ相対回転不能に支持されて、ピストン１５に推力を付与する筒状出力部材３６と、入力ロッド３５と筒状出力部材３６との間に周方向に沿って間隔を置いて複数配置され、入力ロッド３５及び筒状出力部材３６のそれぞれに係合される遊星ロッド３７と、遊星ロッド群３７・・・と筒状出力部材３６との間に配置され、筒状出力部材３６と遊星ロッド群３７・・・との相対回転に対して付勢力を付与するコイルスプリング３９と、を備えている。これにより、制動力を確保しつつ、応答性を向上させることができる。【選択図】図１
