Supporting device for disk brake friction pads

Abstract

A novel supporting device for the friction pads of a disk brake is provided in which a frame straddling a disk rotating in tandem with the wheel is fixed to a non-rotating member of the vehicle, and a caliper slidable in the axial direction of the rotating disk is set in the fixed frame. One end of each of two friction pads are interlocked with the frame such that the trailing ends of the pads slide in the axial direction of the rotating disk. The supporting device incorporates a thin plate set in the interlocking area between the fixed frame and the friction pads wherein the thin plate is molded into a pair of sliding members corresponding in structure to the interlock between the fixed frame and the friction pads. The lower edge of a connecting bar between the two sliding members is bent to a width narrower than the width of the recessed groove molded in the fixed frame for the rotating disk, thereby forming an anti-slippage ledge which abuts the recessed groove to regulate the sliding of the friction pads in the axial direction of the rotating disk. Moreover, a pair of retaining arms integrally extend from the inner end of each sliding member, and lock onto the slide face of the fixed frame to prevent the displacement of the supporting device in the direction orthogonal to the axis of the rotating disk.
