PROBLEM TO BE SOLVED: To provide an ink inhaler such that a flange part of a piston does not deteriorate in an early stage in spite of repetitive use.SOLUTION: An ink inhaler comprises: a cylindrical ink tank having an ink reservoir part for reserving ink defined on an axially rear side; a piston having a flange part fitted to an inner peripheral surface of the ink reservoir part slidably in an axial direction of the ink reservoir part and liquid-tightly, and a rod extending from the flange part toward an axially rear side of the ink tank; and a knob connected inside the ink tank rotatably to the axially rear side of the ink tank with respect to the ink tank. The ink inhaler is characterized in that: a guided part which is sectioned in a non-circular shape is formed at least partially at the rod; a piston guide having a guide part where at least a part of a side face of the guided part of the rod is slid axially behind the ink reservoir part of the ink tank; and a projection part overlapping at least a part of the guide part when viewed from an axial direction is formed axially behind the guided part of the rod.SELECTED DRAWING: Figure 1 |
