Title:
SEALING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/200696
Kind Code:
A1
Abstract:
Provided is a sealing structure capable of exhibiting an excellent effect of improved sealing performance and reduced friction between a shaft member and a bushing. This sealing structure comprises a shaft member (13), a bushing (11) having a shaft bore (11c) into which the shaft member (13) is inserted, a pressure receiving member (16) having a facing surface (16a) which faces towards an end face (11b) of the bushing (11) on one side in the axial direction x (lower side (b)), and an elastic member (14) for pressing the bushing (11) against the pressure receiving member (16) from the other side in the axial direction x (upper side (a)). A first coating layer (12A) is formed between the outer circumferential surface of the shaft member (13) and the inner circumferential surface (11d) of the shaft bore (11c) of the bushing (11), and a second coating layer (12B) is formed between the end face (11b) of the bushing (11) on the one side in the axial direction x (lower side (b)) and the facing surface (16a) of the pressure receiving member (16).
