Abstract
Primary objective of the present invention is to provide a seal device wherein the seal surfaces of the device are always brought into close contact against the side walls of the mounting slot regardless of fluid conditions. The seal device has two seal portions located to both sides of a bight shaped elastic portion which has a “U”-shaped cross section wherein the respective seal portions have a first side portion and a second side portion. The second side portions of the seal portions abut against each other in a symmetric manner in order to form a “W”-shaped seal body element. The end portions of the both second side portions of the seal body element are joined and seal surfaces are defined on the outer side surfaces of the both first side portions.
