PROBLEM TO BE SOLVED: To provide an excellently maintainable diecasting device capable of more uniformly applying a lubricant to the inner wall of a plunger sleeve. SOLUTION: A ring-shaped member 10 is inserted into an insertion part 13a of a plunger rod 13. At the plunger rod 13, a lubricant feed path 12 for feeding a lubricant is formed, and, at the ring-shaped member 10, a plurality of discharge holes 15 communicating with the lubricant feed path 12 are radially formed in the radial direction of the ring-shaped member 10. Even if the discharge holes 15 are clogged with foreign matters intruded into the lubricant, and the casting cycle is stopped, the ring-shaped member 10 can be easily removed from the plunger rod 13, thus its maintainability is excellent.
