    摘要： The purpose of the present invention is to provide a ball joint dust cover with good sealability that is able, even in low temperature environments, to limit the occurrence of gapping of the so-called small diameter opening and to effectively prevent infiltration of sediment and dust into the dust cover from the outside due to reduction in sealing performance at the small diameter opening. A ball joint dust cover made of a rubber-like elastic material in which: the ball head section formed on one end of a ball stud is held in a socket; the shaft of the other end of the ball stud is tightened and fixed to a knuckle; the large diameter opening of one end is fixed and held on the outer circumferential surface of the socket; the small diameter opening at the other end, to which a hard ring is integrally molded, is held on the shaft; and a membrane section, which connects the large diameter opening of the one end to the small diameter opening of the other end, is provided. The ball joint dust cover has a configuration wherein the inner circumferential surface of the hard ring is mated with the outer circumferential surface of a retainer, which has a cylindrical portion that is fitted and held on the outer circumferential surface of the shaft.

    摘要： Provided is a seal ring which can be easily mounted into a chain, can be maintained stably in the mounted state, and can exhibit consistent sealing performance. A seal ring for sealing a chain is mounted in an axially compressed state between an outer link plate which is disposed on the outer peripheral side of a connection pin and an inner link plate which is disposed on the outer peripheral side of the connection pin with a bush provided therebetween. The seal ring has an annular base section, a first outer peripheral lip, a second outer peripheral lip, a first end surface lip, a second end surface lip, and an inner peripheral protrusion. When a bush is press-fitted to the inner peripheral side of the seal ring, the inner peripheral protrusion comes into contact with the bush to generate rotational moment which obliquely twists the seal ring. When the twisting occurs, the first outer peripheral lip and the second outer peripheral lip come into contact with the outer link plate or the inner link plate while falling radially outward.

    摘要： In order to achieve cost reduction for fuel cell stacks, gaskets (1 (2)) for a fuel cell are formed integrally by a rubber-like elastic material in the outer periphery of GLDs (3 (4)), which are interposed between separators (6 (7)) and an MEA (5), and are in close contact with the separators (6 (7)). On the surfaces of these gaskets (1 (2)) facing the separators (6 (7)), a gas lead-in groove (1 b) is formed extending such that manifold holes (1 a (2a)) provided in these gaskets (1 (2)) and a gas reaction area (10A) formed by the MEA (5) are communicated to each other. This gas lead-in groove (1 b) can be formed at the same time as the forming of the gaskets (1 (2)) by a rubber-like elastic material, and a gas lead-in groove need not be formed on the separator (6 (7)) side; therefore, costs can be reduced.
