Abstract: Provided is a silencer for a laminated leaf spring, with which it is possible to more effectively reduce abnormal noise generated in conjunction with deflection of the laminated leaf spring, as compared to when a conventional silencer for a laminated leaf spring is used. This silencer (1) for a laminated leaf spring is arranged between adjacent leaf springs (60a-60c) in the direction in which the multiple leaf springs (60a-60c) forming a laminated leaf spring (6) are stacked. A thermoplastic elastomer that has lower hardness than thermoplastic synthetic resins such as polyethylene resin, polyacetal resin, polyamide resin, and polyester resin, and that has a better sliding characteristic than rubber materials such as natural rubber and synthetic rubber, is used for the material of the silencer (1).
