Fluid device coupler and fluid device coupling structure

Abstract

The present invention provides a fluid device coupler which can achieve satisfactory workability while saving space without reducing sealing performance, wherein the fluid device coupler comprises a coupling base having a depressed part at least partially curved in an arc shape, a first end edge side and a second end edge side continuous with an inner surface of the depressed part, and an opening portion formed between the first end edge side and the second end edge side a blockage member protrudable from the first end edge side toward the second end edge side and retractable in a circumferential direction from the second end edge side toward the first end edge side, and a sliding structure configured to slidably move the blockage member toward the second edge side of the coupling base without changing a distance radially from the coupling base.
