[Problem] To provide a stem pipe seal device configured so as to cool and lubricate the portion of a first seal ring which is in sliding contact with a liner, thereby preventing the wear of the seal ring and improving the durability of the seal ring. [Solution] A stern pipe seal device (12) for a propeller shaft (10) rotatably supports a propeller (21). The stem pipe seal device is provided with: a housing (13) which is fitted over the liner (11) of the propeller shaft (10) and which holds seal rings; a first seal ring (1) which, among the seal rings, is located closest to the stem; a second seal ring (2) which is disposed on the front side, with respect to the ship, of the first seal ring (1) at a distance from the first seal ring (1); and a discharge opening (31d) which discharges lubricating oil for cooling the first seal ring (1). The stem pipe seal device is characterized in that the discharge opening (31d) is disposed near the slide contact section (G) where the liner (11) and the first seal ring (1) are in sliding contact with each other.
