LAMINATED SHIM FOR DISC BRAKE

PROBLEM TO BE SOLVED: To realize a structure of a laminated shim capable of preventing the displacement amount in a circumferential direction between a base shim plate and a cover shim plate from becoming excessive.SOLUTION: A base side locking piece 10a, 10b, which extends from a flat-shape base side substrate portion 9 of a base shim plate 2 toward the base shim plate 2 side in a lamination direction of cam plates, and a cover side locking piece 21a, 21b, which extends from a flat-shape base cover side substrate portion 20 of a cover shim plate 3 in the same direction as the base side locking piece 10a, 10b, are overlapped in a radial direction. In this state, the cover side locking pieces 21a, 21b are inserted into base side through holes 12 provided in the base side substrate portion 9, and circumferential end portions of the cover side locking pieces 21a, 21b are opposed to movement-restricting surfaces 24, which are circumferential side edges of the base side through holes 12.SELECTED DRAWING: Figure 6 【課題】ベースシム板とカバーシム板との周方向に関するずれ量が過大になるのを防止できる、積層シムの構造を実現する。【解決手段】ベースシム板２の平板状のベース側基板部９から、カム板同士の積層方向に関してベースシム板２側に伸長したベース側係止片１０ａ、１０ｂと、カバーシム板３の平板状のカバー側基板部２０から、ベース側係止片１０ａ、１０ｂと同方向に伸長したカバー側係止片２１ａ、２１ｂとを径方向に重ね合わせる。この状態で、カバー側係止片２１ａ、２１ｂを、ベース側基板部９に設けたベース側透孔１２に挿入し、カバー側係止片２１ａ、２１ｂの周方向端部を、ベース側透孔１２の周方向側縁である、移動規制面２４に対向させる。【選択図】図６
