SEALING DEVICE

摘要

A sealing device having a side lip, in which, when a multiple of such sealing devices are stacked one on top of the other, interference between the side lips is effectively suppressed. The sealing device is installed on one of two members rotating relative to each other and slidably in intimate contact with the other member. The sealing device is constructed by combining a mounting ring fitted on the one member and a rubber-like elastic body coated on the mounting ring and has the side lip formed from the rubber-like elastic body and slidably in intimate contact with the other member. The mounting ring has a circular hollow cylindrical part at a portion fitted on the peripheral surface of the one member. The rubber-like elastic body has a rubber step part provided on axially one side of the circular hollow cylindrical part. When a multiple of sealing devices of the invention are stacked one on top of the other, the rubber step part of one sealing device and the circular hollow cylindrical part of a corresponding upper sealing device have a positional relationship in which the rubber step part allows the circular hollow cylindrical part to be placed on it, and the side lip of the one sealing device is dimensioned so as not to interfere with the upper sealing device even when they are in such a positional relationship.
