Abstract
In a flow path member joining structure for enabling a liquid to flow by attaching, to a first member having a first flow path, a second member having a second flow path and aligning the first flow path and the second flow path with each other, the first flow path is open toward a first end face of the first member, and an enlarged diameter portion whose inner diameter gradually increases toward the first end face is formed at an end of the first flow path, and the second flow path is open toward a second end face of the second member.

A flow path member joining structure for enabling a liquid to flow by attaching, to a first member having a first flow path, a second member having a second flow path and aligning the first flow path and the second flow path with each other, wherein:
- the first flow path is open toward a first end face of the first member, and an enlarged diameter portion whose inner diameter gradually increases toward the first end face is formed at an end of the first flow path, and
- the second flow path is open toward a second end face of the second member.
A column attaching/detaching unit for attaching a column having two end faces, liquid passage holes open at centers of the two end faces, and a column flow path connecting the two liquid passage holes, the column attaching/detaching unit comprising:
- a pair of pedestals facing the two end faces, respectively;
- communication holes open to respective placement portions of the pair of pedestals;
- liquid passage flow paths communicating with the respective communication holes;
- an enlarged diameter portion formed at an end of each of the liquid passage flow paths and having an inner diameter that gradually increases toward a respective placement portion;
- and
- a crimping mechanism causing the pair of pedestals to approach the two end faces to join the liquid passage flow paths and the column flow path.
