に生じやすいという問題があった。However, in the reservoir having the above construction, the annular seal portion may be slightly displaced from the inner peripheral side of the opening end face of the injection portion depending on how the cap is tightened to the injection portion. However, there is a possibility that a gap may be formed between them and cause liquid leakage.
Moreover, in order to allow the locking claws provided on the cap to pass through, a plurality of notches are formed intermittently in the circumferential direction at the opening end portion of the injection portion, so that the opening end portion easily undergoes thermal deformation. When such thermal deformation occurs, there is a problem that the above-described annular seal portion and the inner peripheral side of the opening end surface of the injection portion are more likely to be displaced.

能である。According to the reservoir having such a structure, the cap 11 with the protrusion 14 supporting the seal member 17 is provided.
Is mounted on the injection part 3 through the notch part (not shown) of the flange part 4, and in this state, the cap 11
By rotating the cap 11 by a predetermined angle,
When the protrusion 14 enters the lower side of the flange portion 4, the protrusion 14 is engaged with the injection portion 3. At the time of this engagement, the seal member 17 moves from the same position as the annular seal portion 25 to the lid portion 13 side. The annular projection 27 provided so as to project is the cap 1
1 is fitted in the annular groove 28 provided in the lid portion 13, so that the radial positions of the cap 11 and the injecting portion 3 match at the time of engagement. 25 is reliably positioned in the radial direction, and reliably contacts the taper portion 10 on the inner peripheral side of the opening end surface of the injection portion 3 regardless of how the cap 11 is tightened. Therefore, no gap is formed between the annular seal portion 25 and the taper portion 10, and liquid leakage can be prevented. In the embodiment of the present invention, the seal member 17 is provided with the annular protrusion 27, and the cap 11 is provided with the annular groove 28 that fits into the annular protrusion 27. However, the protrusion is not necessarily annular. Need not be, lid 13
It may be a single protrusion projecting to the side and partially extending in the circumferential direction, or a plurality of protrusions projecting to the lid 13 side and provided at intervals in the circumferential direction. It may be provided. Also, in the embodiment of the present invention, the annular seal portion 25 of the seal member 17 is used.
Although the annular protrusion 27 is provided so as to project from the same position to the lid portion 13 side, the position where the protrusion is formed may be radially inward of the annular seal portion 25 of the seal member 17 or outward. However, the point is that the seal member 17 may be provided at an appropriate position as long as it can prevent the radial movement of the seal member 17. Also in this case, the protrusion does not necessarily have to be annular. Furthermore, in the embodiment of the present invention, the injection part 3 has a cylindrical shape, and the cap 11 has the cylindrical part 12. However, if the injection part 3 and the cylindrical part 12 are cylindrical,
It is also possible to have a polygonal shape such as an elliptical shape or a hexagonal shape.
