摘要： The present invention provides a mechanical seal preventing the deformation of the cartilage and exhibiting a good sealing performance. In said mechanical seal, the deformation of the back portion 16d of the cartilage due to the force from the pump housing 3 is absorbed by forming a groove portion 16f having cross section substantially a triangular shape at the back portion 16d of the cartilage 16. As a result, the deformation hardly transfers to the area near the inner tube portion 16a of the cartilage 16 and the inner tube portion 16a of the back portion 16d; and the relative position of the seal ring 14, and the bellows 15 or so scarcely changes with respect to the structure of the mating ring 11 or so on the side of the rotation axis 2, thus the assembling length and the assembled load of the mechanical seal 9 does not change, which allows the mechanical seal 9 to exhibit good sealing performance.

摘要： A primary technical goal of a mechanical seal device of the present invention is to decrease assembly cost thereof as well as machining cost thereof and to prevent wear of seal surfaces by preventing occurrence of squealing noises of the seal surfaces. The mechanical seal device comprises a first seal ring which is one of a pair of seal rings and disposes an engagement portion at the outer circumferential surface, a retainer ring which has a first support portion supporting an inner diameter surface of the first seal ring and a second support portion engaging the engagement portion and is fixed with either a seal housing or a shaft, and a gasket which joins the retainer ring and the first seal ring in a sealing manner, wherein an engagement clearance (C) formed in a rotational direction between the engagement portion and the second support portion is within 0.5 mm.
