Abstract
A squeak preventing shim for a disk brake for an automobile has a squeak preventing effect, even if no lubricant is used, and also prevents decreased durability due to buckling, flow, etc. A shim construction is formed with a plurality of grooves or recesses in rubber layers 2 disposed on two surfaces of a metal plate in a rubber coated member. Owing to these grooves or recesses, apparent transversal elastic modulus of the rubber layers is lowered and a squeak preventing effect due to vibration in a parallel direction to the shim can be obtained, even if no lubricant is used. Further, since longitudinal elastic modulus does not vary much, the shim construction is durable.
