るメカニカルシール。 A fixed ring airtightly attached to the inner periphery of the housing, and a rotating ring airtightly attached to the outer periphery of the rotating shaft and biased in the axial direction by a spring so as to closely slide between the end faces facing the fixed ring. In the mechanical seal, the torque detection ring has a flexible piece between opposing circumferential surfaces of the housing and the fixed ring that engages in the circumferential direction with a rotation stopper formed on the outer circumferential surface of the fixed ring and has a strain gauge affixed thereto. A mechanical seal characterized by being interposed and fixed.
