Document Type and Number:
Japanese Patent JP2023000168
Kind Code:
A
Abstract:
To provide a ratchet fitting which is improved in accuracy of a torque regulation value, and a piping connection structure.SOLUTION: A ratchet fitting 100 comprises a screw part 100A and an operation part 100B. Either of the screw part 100A and the operation part 100B has an engagement member, and the other of the screw part 100A and the operation part 100B has an elastic member and a holding member formed separaTely from the elastic member. A protrusion protruding inward is formed at an internal peripheral face of the engagement member, and a salient part salient outward is formed at an external peripheral face of the elastic member. The elastic member and the engagement member can transmit a rotation force by the engagement of the protrusion and the salient part, and are fit to each other so as to be releasable in engagement of the protrusion and the salient part by deformation of the elastic member. The elastic member has a first fitting part, the holding member has a second fitting part, and the holding member and the elastic member are fit to each other so that the first engagement part and the second engagement part are fit to each other in a rotation direction.SELECTED DRAWING: Figure 2
