Abstract
A silencer for a leaf spring assembly. The silencer is disposed between end portions of leaf springs. The silencer has a two-layer structure which has a fixing layer and a sliding layer which are integrally formed. The fixing layer has a projection portion, and the projection portion has an engagement portion at a leading end portion thereof. The fixing layer, which is fixed at the fixing side leaf spring, has a tensile strength higher than the sliding layer. The sliding layer, which abuts the sliding side leaf spring, has a hardness lower than the fixing layer. The projection portion of the fixing layer can have sufficient strength to resist the shearing force. In the sliding layer, undesirable noise generation is difficult, and even when a load transmission portion of an end portion of the sliding side leaf spring partially abuts the sliding layer, undesirable noise generation can be prevented.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
