のメカニカルシール。[Claims for Utility Model Registration] (1) A fixed ring is provided on the inner periphery of the body on the housing side via an O-ring, and this fixed ring is prevented from rotating by a fixed member fixed to the rotating shaft side. The rotating ring is slidably opposed to each other via an O-ring, and the rotating ring is elastically pushed toward the fixed ring via a spring retainer by the urging force of a coil spring whose one end is supported in contact with the fixed member. What is claimed is: 1. A mechanical seal that is pressed by a coil spring, characterized in that a buffer member is interposed between a contact portion between the fixing member and the coil spring. (2) The mechanical seal according to claim 1, wherein the buffer member is made of a rubber material.
