Abstract
The strength and rigidity of pad springs are increased with a simple structure to prevent deformation and so forth of the pad springs caused by external force. A mounting member is provided with pad springs for resiliently supporting friction pads. Each pad spring has guide plates, a connecting plate, an engagement plate, radially urging portions, circumferentially urging portions, reinforcement, etc. The reinforcement includes a rectilinear reinforcement formed on a flat plate portion of the connecting plate by embossing, for example, and oblique reinforcements formed on joint portions of the connecting plate. Thus, the joint portions and so forth of the pad springs can be prevented from being deformed by external force when the brake is activated or during assembling operation, for example, and hence it is possible to prevent positional displacement of the guide plates, etc. that would otherwise be caused by the deformation of the joint portions.
