A vibration damping shim structure is provided, which not only can sufficiently exert vibration damping effect in a wide range of temperatures, but also can prevent a squeal phenomenon particularly in low temperatures. A rubber coating layer a1 is formed on one side of a first constraint plate a2 of a metallic plate and a second constraint plate a4 is stuck to the other side of the first constraint plate a2 with a adhesive layer a3 placed in-between. The ratio of the thickness of the first constraint plate a2 to a sum total of the thickness of the back plate b1 forming a disc brake B and the second constraint plate a4 is taken as within 0.1 to 0.2, and the second constraint plate a4 is used so as to be brought into contact with the back plate b1.
A vibration damping shim structure having a structure, wherein a rubber coating layer is formed on one side of a first constraint plate and a second constraint plate is stuck to the other side of the first constraint plate with an adhesive layer placed in-between, and wherein a ratio of the thickness of the first constraint plate to a sum total thickness of a back plate of a disc brake pad and the second constraint plate is within a range of 0.1 to 0.2 and the second constraint plate is brought into contact with the back plate.
