Abstract
PURPOSE: To improve sealing capacity by a self-sealing effect by forming fluid passage at a top part of an inner peripheral lip.
CONSTITUTION: When hydraulic pressure acts upon a top part 2 of an inner peripheral lip 1 of a U packing 4 for a rod with a connecting groove 3 in a diameter direction while the top part 2 is contacted with an inside end face 10 of a mounting groove 9, the hydraulic pressure goes into a space 13 between the inner peripheral lip 1 and an outer peripheral lip 11 through the connecting groove 3 at the top of the inner peripheral lip, so that a self-sealing effect is generated by pressure to prevent leakage.
