溝を形成するとともに、該環状溝とシールリング背面を
連通ずる連通孔を穿設してなり、シール液を環状溝に導
入するようになることを特徴とする軸封装置。(1) A seal ring provided on the rotating shaft side is pressed against a sliding member provided on the housing side so as to be slidable and rotatable by the hydraulic pressure of a sealing liquid filled on the back side of the seal ring. In the shaft sealing device, an annular groove is formed on the sliding surface of the seal ring, and a communication hole is bored through which the annular groove communicates with the back surface of the seal ring, so that sealing liquid is introduced into the annular groove. A shaft sealing device characterized by: （２）前記連通孔が多数個穿設され、隣接する連通孔の
少なくとも開口端が傾斜方向を逆にするように周方向に
向かって傾斜してなり、シールリングの回転に伴ないシ
ール液を強制供給するようになることを特徴とする実用
新案登録請求の範囲第１項記載の軸封装置。(2) A large number of the communication holes are formed, and at least the opening ends of adjacent communication holes are inclined toward the circumferential direction so that the direction of inclination is reversed, so that the sealing liquid flows as the seal ring rotates. The shaft sealing device according to claim 1, characterized in that the shaft sealing device is forcibly supplied.
