Disc Brake

Abstract: A pad spring (24) on a rotation entry side in a disc rotation direction has: a first support part (131) that elastically supports a friction pad (27) in the disc rotation direction; and a second support part (120) that is offset in a disc radial direction with respect to the first support part (131), covers a torque receiving part (60), and elastically supports the friction pad (27) in the disc rotation direction. One of the first support part (131) and the second support part (120) is in contact with the friction pad (27), and the other has a first state in which there is a gap (S) between the other support part and the friction pad (27), and a second state in which the gap (S) is filled by movement of the friction pad (27).
