PROBLEM TO BE SOLVED: To provide an injection device capable of improving the flexibility of a standby position of a plunger.SOLUTION: An injection device 3 includes: a sleeve 7 communicating with a cavity 105; a plunger 9 which pushes out a molten metal (a molding material) in the sleeve 7 to the cavity 105; and an injection cylinder 11 for driving the plunger 9. The sleeve 7 includes a sleeve body 41 and a movable member 43. The sleeve body 41 is formed into a cylindrical shape extending in a direction that inclines in a horizontal direction and an opening 41a is formed at the upper side of the sleeve body 41. The movable member 43 covers the opening 41a and adjusts its position relative to the sleeve body 41 in a longitudinal direction. Further, a hot water supply port 7a, which overlaps with the opening 41a, has a longitudinal diameter smaller than the opening 41a, and is used for supplying the molten metal to the sleeve 7, is formed at the movable member 43. |
