<p>PROBLEM TO BE SOLVED: To provide a flow path connecting device that prevents an opening state of a switching cock from being changed.SOLUTION: A flow path connecting device 30 comprises: a tube 31 having a first flow path in which intracavitary fluid flows; and a male lure connector 32. The male lure connector 32 has an axial direction through hole 32h serving as a second flow path communicating with the first flow path with the tube 31 connected thereto, and is provided with a male lure part 34 and a protrusive member 35. The male lure part 34 is formed in a tapered shape that tapers toward a tip end, and capable of airtightly abutting with an inner surface wall of a taper hole 23h communicating with a discharge hole 21 arranged at a female lure part 23r of a discharge tube connection part 23 being a female lure connector that forms a port and through which the intracavitary fluid passes. The protrusive member 35 is provided in a forward protruding manner than a tip end surface of the male lure part 34, and has an outer peripheral surface parallel with a through hole 25h of a rotation cock and an outer diameter formed to be smaller than an inner diameter of a flow path in the discharge tube connection part 23.</p> |
