Abstract: A damper is provided by a plurality of chambers defined between stacked thin sheet members and containing a fluid for flowing therein through a communicating section, the chambers being made to be of a small height in the direction perpendicular to the plane of the sheet members and to form a buffer section with at least one of the chambers. With such damper employed in electromagnet assemblies and eventually relays including the assemblies, they can be sufficiently minimized in size, and their manufacture can be also made extremely easier.
