摘要： A seal structure has a metal gasket arranged between a pair of casings. The metal gasket is provided with a bead portion in an inner peripheral side of a planate outer peripheral portion, and a bent portion in an outer peripheral side. When the metal gasket is pinched by a pair of casings, the bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, and comes into contact its outer peripheral end portion with one casing, whereby any gap in which salt water stays is not formed between one casing and the outer peripheral portion, and the bent portion comes into contact with the other casing, whereby any gap in which the salt water stays is not formed between the other casing and the outer peripheral portion.

摘要： Salt water is piled up in (attached to) a gap between a metal gasket and a casing, whereby the corrosion of the casing is hard to be generated by the staying of the salt water and the seal function is maintained over a long term. There is provided a seal structure including one metal gasket which is arranged between a pair of casings. Wherein the metal gasket is provided with a planate outer peripheral portion and a bead portion which is formed by rising up from an inner peripheral end portion of the outer peripheral portion, and is arranged so that the bead portion comes into contact with the one casing, and the outer peripheral portion comes into contact with the other casing, the bead portion elastically deforms so as to reduce its height and the outer peripheral portion elastically deforms on the basis of the elastic deformation of the bead portion, when the metal gasket is pinched by the pair of casings, and a leading end of the outer peripheral portion comes into contact with the one casing at this time, whereby any gap in which salt water stays is not formed between the one casing and the metal gasket.

摘要： Provided are an air flow generation structural body and a sealing structure that can inhibit ingress of dust even further. An air flow generation structural body includes a main body (61) disposed in a gap between an attachment target (53) to which a sealing device (20) is attached and a disc-shaped member (11) that is integrated with a shaft member (14) so as to extend from the shaft member (14) toward an outer periphery side. The shaft member (14) passes through a through-hole (53h) in the attachment target (53) and is rotatable around an axis. The main body (61) is attached to the shaft member (14) so as to be rotatable together with the shaft member (14). The air flow generation structural body further includes a plurality of blade portions (62) formed on an outer peripheral surface (61)g of the main body (61) to generate an air current. Each of the blade portions (62) extends along a centrifugal direction perpendicular to the axis x and is parallel to the axis x.
