Title:
FITTING, PIPE CONNECTION STRUCTURE, AND LIQUID CHROMATOGRAPHY
Document Type and Number:
Japanese Patent JP2023000169
Kind Code:
A
Abstract:
To provide a fitting that enables secure connection of piping while preventing an increase in size of a connection structure, a piping connection structure including the same, and a liquid chromatography including the same.SOLUTION: A fitting 100 comprises: a screw part 100A that is rotatable around an axis extending in one direction; an operation part 100B that applies torque around the axis to the screw part 100A; and a rotation auxiliary member 6 configured to be engageable with the operation part 100B. The rotation auxiliary member 6 is provided with a slot 60d that extends from a first end to a second end and is provided with a first projection that projects outward. The positional relationship of the first projection is set such that, when a force in a first rotation direction is applied to the first projection while the rotation auxiliary member 6 is engaged with the operation part 100B, the width of the slot 60d is changed to increase an engaging force between the rotation auxiliary member 6 and the operation part 100B.SELECTED DRAWING: Figure 2
