Title: ATTACHMENT FOR LIQUID INJECTION
Abstract:
The present invention addresses the problem of providing an attachment for a liquid injection that is configured to be able to sufficiently absorb a dimensional change caused by a dimensional error on a liquid injection tool leading end side or a positioning (mounting) error to the liquid injection tool leading end side. This problem is solved by an attachment for a liquid injection, the attachment being formed into a cylindrical body, having: an insertion port 2 at a rear end 3 thereof, through which a leading end side 101 of a liquid injection tool 100 is inserted; a liquid outlet 5 at a front end 4 thereof; an annular lip 7 formed to bulge around the liquid outlet 5; and at least one reduced-diameter portion 80 formed on the outer cylindrical surface of the cylindrical body.
