Document Type and Number:
WIPO Patent Application WO/2019/167383
Kind Code:
A1
Abstract:
[Problem] To provide a sealing structure that allows accurate positioning in an attachment space 14. [Solution] This sealing structure has: a sealing device (21) that has a first seal lip (27) having a first seal lip leading end (27a) and that has a holding ring (22) for holding the first seal lip (27); and a plurality of members that demarcate the attachment space (14) into which the sealing device (21) is mounted and that has an inner circumferential wall part (15) located on the inner circumferential side of the sealing device (21), a first end wall part (16) located at one axial side of the sealing device (21), and a second end wall part (17) located at the axial other side of the sealing device (21). The first seal lip leading end (27a) has tightening interference with respect to the inner circumferential wall part (15) and the first end wall part (16) so as to radially outward press the holding ring (22) by a radial reaction force and press the holding ring (22) against the second end wall part (17) by an axial reaction force.
