    摘要： A tightening device comprises an upper plate, a lower plate disposed below the upper plate in parallel thereto, a nut rotating gear supported by the lower plate so as to be rotatable in a horizontal plane, and a spur gear provided on an underside of the upper plate and meshable with the nut rotating gear for rotating the nut rotating gear. The upper plate has a portion fittable to a flange of an externally threaded member for preventing the rotation of the threaded member, while the nut rotating gear has a portion fittable to a nut. With the nut manually tightened on the threaded member in advance, the flange fitting portion of the upper plate is fitted to the flange, the nut is fitted in the fitting portion of the nut rotating gear, and the spur gear is thereafter rotated, whereby the nut rotating gear is driven to tighten up the nut on the threaded member.

    摘要： A pipe joint comprises a pair of tubular joint members, an annular gasket interposed between abutting end faces of the joint members, and a nut for joining the joint members. A seal projection is formed on the abutting end face of each joint member at a position radially outward of an inner periphery of the end face. When an end of the seal projection is brought into contact with an end face of the gasket by tightening the nut, a clearance is formed between an outer flat portion of the abutting end face of each joint member and the gasket end face opposed thereto. The clearance is greater than a clearance between an inner flat portion of the abutting end face of each joint member and the gasket end face opposed thereto, and is eliminated when the nut is completely tightened up.
