SEAL DEVICE
Document Type and Number:
Japanese Patent JP2018105310
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a seal device which enables reduction of unevenness of surface pressure of a lip part which is exerted on an outer peripheral surface of a shaft.SOLUTION: A seal device 10 of the invention is attached to a space between an outer cylinder 50 and a shaft 70 inserted into the inner periphery side of the outer cylinder 50 in a shock absorber. The seal device 10 comprises: an outer periphery side seal 20 fixed to an inner periphery of the outer cylinder 50; and an inner periphery side seal 30 which is positioned at the inner periphery side of the outer periphery side seal 20 and slidably contacts with the shaft 70. The outer periphery side seal 20 and the inner periphery side seal 30 are connected by a connection part 40 in which at least a part thereof may elastically deform in a radial direction to cause the inner periphery side seal 30 to be displaced in the radial direction.SELECTED DRAWING: Figure 1
