In a mechanical seal consisting of a rotating ring and a movable ring that is always urged to be in contact with the fixed ring by a spring provided between the rotary ring and the movable ring, the movable ring has a sliding contact surface with the shaft that has more liquid than the shaft packing. A mechanical seal characterized by incorporating a movable ring having a circumferential groove formed at a side position and having one or more holes penetrating from the groove to the outside. （２）回転環と係合する移動環の係合片部に貫通孔を形
