摘要： In a reciprocating sealing device sealing two members by mounting a packing to a mounting groove in one of two relatively reciprocating members, and bringing the packing into contact with the other member, the packing is provided with an annular base part, a stationary side lip, and a sliding side lip. A back ring having a lower hardness than the packing is interposed between the annular base part and a groove side surface of the mounting groove. The back ring forms a space region in relation to the other member. The annular base part is provided with a shape that the annular base part does not protrude out of an extension of a peripheral surface of the sliding side lip in a free state by forming a cross sectional shape of a heel part into a circular arc shape or a taper shape.
