Abstract
A sealing member according to the present invention is a sealing member against a synthetic oil containing an ester-type additive, and includes 95.0% by mass or more and 99.5% by mass or less of a para-phenylene diisocyanate-based polyurethane and 0.5% by mass or more and 5% by mass or less of a same compound as the ester-based additive. The sealing member according to the present invention has a smaller friction coefficient and more excellent deformability than conventional sealing members and that can inhibit swelling caused by a synthetic oil.
