Disclosed is a structure such that when pad clips (15g) are to be mounted, it is possible to handle return springs (16e) and the pad clips (15g) as integral articles (subassemblies), thereby facilitating mounting work. Constraining sections (24, 24) are provided at both axial ends of each of the pad clips (15g). Furthermore, the return springs (16e) are composed of inner spring elements (26g) and outer spring elements (26h). These two types of spring elements (26g, 26h) are helical torsion springs provided with helical sections (27c). Abutting sections (59, 59) are provided on the spring elements (26g, 26h), respectively. The abutting sections (59, 59) are pressed against the inner surfaces of the constraining sections (24, 24) by elastic restoring forces. Moreover, the central axes of the coil sections (27c) are substantially oriented in the rotational direction of the rotor. |
