Abstract: To satisfy a requirement that a mechanism and a necessary component which are adapted to the attachment of a bolt and a nut in all directions, and can cope with vibration from all the directions should be remodeled while solving a problem that, when the bolt and the nut are exposed for a long period of time even if they are fastened, the bolt slides by its own fateful structure, also when minute and slight loosening occurs between the bolt and the nut at a spiral contact face, the bolt and the nut are loosened by return rotation, and a fastening axial force is lowered.SOLUTION: A loosened tapered conical cone protrusion is formed at an upper nut, two nuts are made to tightly adhere to each other and fixed by screwing the upper nut to a lower nut by the same conical socket recess, a bolt is screwed up by screwing one nut, and a reaction force is generated at the bolt, thus not causing loosening. A slightly-decentered screw is arranged at the upper nut, an eccentric core center line of the nut is pulled up to a bolt center line by the screwing of the nut to the conical socket and the bolt which is fixed to a cone, and the engagement of the bolt and the screw of the nut is fixed at a slide spiral contact face.SELECTED DRAWING: Figure 1

Abstract: To provide a stirring rotary body improved in stirring efficiency and to provide a liquid treatment device using the stirring rotary body.SOLUTION: A stirring rotary body 1 of the present invention includes a body portion 10 having a circular or polygonal cross section perpendicular to a rotation shaft 2. The body portion includes: a plurality of slits 20 extending from a lower surface to a side surface; and a plurality of columnar portions 30 located between the plurality of slits. The lower surface of each slit serves as a suction port 21 for a to-be-treated liquid. The side surface serves as a discharge port 22 for the to-be-treated liquid. A space connecting the suction port and the discharge port serves as a flow passage 23 for the to-be-treated liquid. An upper surface 23a of the flow passage inclines upward from inside to outside in a radial direction around the rotation shaft. The to-be-treated liquid is subject to centrifugal force and is jetted not only in a horizontal direction but also in an obliquely upward direction along the upper surface of the flow passage. Since the to-be-treated liquid is jetted obliquely upward, a flow that is vertically rotated in the stirring furnace is easily formed, so that the stirring efficiency can be improved. In addition, by providing a through-hole in the columnar portion, a more complicated circulation flow can be formed.SELECTED DRAWING: Figure 1
