A silencer for a leaf spring assembly is provided which can realize both improvement in strength of projection portion and prevention of undesirable noise generation and which allows production for silencers to be easier and which can reduce the number of parts of the silencer by simplification of structure of the silencer. A silencer 1 is disposed between end portions of leaf springs 101 and 102 shown in Fig. 1 . The silencer 1 has a two-layer structure which has a fixing layer 11 and a sliding layer 21 which are integrally formed. The fixing layer 11 has a projection portion 12, and the projection portion 12 has an engagement portion 13 at a leading end portion thereof. The fixing layer 11, which is fixed at the fixing side leaf spring 101, has a tensile strength higher than the sliding layer 21. The sliding layer 21, which abuts the sliding side leaf spring 102, has a hardness lower than the fixing layer 11. The projection portion 12 of the fixing layer 11 can have sufficient strength to resist the shearing force. In the sliding layer 21, undesirable noise generation is difficult, and even when a load transmission portion of an end portion of the sliding side leaf spring 102 partially abuts the sliding layer 21, undesirable noise generation can be prevented. |
