PROBLEM TO BE SOLVED: To provide a liquid administration tool capable of suppressing the rotation of a needle tube, and reducing a burden on a living body.SOLUTION: A liquid administration tool 10 includes: a syringe 60 that can accommodate liquid inside; a needle tube 66 that can be communicated with the inside of the syringe 60; an internal structure 40 that holds the syringe 60; a cover member 30 which is energized in the tip direction with respect to the internal structure 40, surrounding the outer periphery of the needle tube 66, and in which an opening 38 is formed on the tip side so that, by moving in the base end direction with respect to the internal structure 40, the needle tube 66 is caused to protrude from the opening 38 in the tip direction; and a grip part 20 formed so as to cover the syringe 60, the internal structure 40, and at least part of the cover member 30, which, by moving in the tip direction with respect to the internal structure 40, discharges liquid in the syringe 60 from the needle tube 66. The internal structure 40 can rotate with respect to the grip part 20, and includes a support part 118 for supporting the syringe 60 in a relatively rotatable manner.SELECTED DRAWING: Figure 2 |
