Disc brake

Provided is a disc brake for which the ease when assembling a friction pad on a mounting member can be improved. The ear sections (7B, 7C) of a friction pad (6) are inserted in a pad guide (3) of a mounting member (2). A side-pressing spring (26) that presses in the rotation direction of a disc (1) is provided on the friction pad (6). Between the mounting member (2) and the friction pad (6), a pad spring (11) is disposed. The pad spring (11) is mounted so as to be able to abut against the pad guide (3) of the mounting member (2) and comprises guide plate sections (15) for guiding the friction pad (6) in the axial direction of the disc (1) and guiding projections (15C) that extend from outer sections (15A) of the guide plate sections (15) outward in the disc axis direction. The guiding projections (15C) are inclined in the disc rotation direction. 提供种盘式制动器，该盘式制动器能够提高将摩擦衬块组装于安装部件时的作业性。摩擦衬块(6)的耳部(7B、7C)被插入到安装部件(2)的衬块引导部(3)。在摩擦衬块(6)上设有向制动盘(1)的旋转方向按压的侧压弹簧(26)。在安装部件(2)与摩擦衬块(6)之间配设有衬块弹簧(11)。衬块弹簧(11)具有以能够与安装部件(2)的衬块引
