摘要： PROBLEM TO BE SOLVED: To provide an alignment coupling, wherein a joining state can be secured in injection molding, and it can follow a change in heat-expansion of a plunger sleeve, and deformation wear of a plunger sleeve and a plunger lot is hardly caused.
SOLUTION: The contact surface between the distal end part of an injection cylinder lot 5 and the rear end part of the plunger lot 3, is formed to have a ruggedly ground surface 20, and a driving shaft side casing 12 which is fixed by outside engagement so as to integrally move in the axial direction to the distal end of the injection cylinder lot 5, is joined to a driven shaft side casing 13 which is engaged outside so as to be shiftable, in the axial direction, to the rear end part of the plunger lot 3. Further, an alignment ring 16 which is engaged outside the plunger lot 3 is arranged in the inner part of the driven shaft side casing 13, and the elasticity in the direction always abutting on the driving shaft side casing 12 with springs 17 is energized to this alignment ring 16.
