Abstract
A puncturing instrument includes a cylindrical main body case having a puncture aperture on a lower end side; a needle holder provided on a puncture aperture side inside the cylindrical main body case; a first elastic object for moving the needle holder to the puncture aperture side; and a second elastic object for pulling the needle holder back to an upper end side inside the cylindrical main body case, from a state in which the needle holder is moved to the puncture aperture side by the first elastic object. A rotator rotates around a rotation shaft fixed to the cylindrical main body case, and is coupled with a coupling portion of the needle holder on a first one of two sides of the rotator with the rotation shaft interposed therebetween and is coupled with the second elastic object on a second one of the two sides of the rotator.
