Abstract: The present invention suppresses the amount of fluid pushed out from an injection needle when confirming whether air has been pushed out of the injection needle. Provided is a syringe that comprises: a cylinder 20; an injection needle 22; a needle base 24; an injection needle cover 26; and a plunger rod 28. The needle base 24 communicates between the inside of the cylinder 20 and the inside of the injection needle 22. The injection needle cover 26, when extended from a folded state, surrounds the injection needle 22. The injection needle cover 26 comprises an injection needle surrounding part. The injection needle surrounding part has at least one cutout 130 in a section facing the needle base 24 and covering the needle base, such that the needle base 24 can be identified from the outside.

Abstract: A injection-needle cover includes an injection needle enclosure portion, which has paired base-side wall portions, a cylinder portion, paired tip-end-side wall portions, an injection needle contact portion, a hook portion, and a needle tip end fixing portion. The injection needle contact portion is disposed at a position in a base-side axial space, which is a boundary between the base-side axial space and an intra-cylinder space. The injection needle contact portion has a force receiving portion and a connecting portion. The force receiving portion receives a force from the injection needle when the force receiving portion comes in contact with the injection needle. The force receiving portion has an easy sliding portion, which is disposed in an area adjacent to an injection needle, and slides more easily along the injection needle than a case where an edge slides along the injection needle.
