PROBLEM TO BE SOLVED: To easily carry out attaching and detaching work of a needle unit to the tip of a pen type injector main body in a injector needle attachment and detachment tool used in the case of attaching and detaching a needle unit which is externally covered with a protective cover to the tip of the pen type injector main body.

SOLUTION: The injector needle attachment and detachment tool 1 used in the case of attaching and detaching the needle unit which is externally covered with the protective cover to the tip of the pen type injector main body has: a tool main body 2 in the state of a bottomed cylinder into which the pen type injector main body is inserted so as to make its tip project; and a guide cylinder 5 which is provided coaxially with the tool main body 2 and slidably in an axial direction inside of the tool main body 2 and which can project by a prescribed length to the tip side of the tool main body 2 by sliding in the axial direction. The inner peripheral surface of the tip of the guide cylinder 5 is formed so that the protective cover can slide so that the tip of the guide cylinder 5 may cover the tip of the pen type injector main body 12 inserted to the tool main body while the guide cylinder 5 is made to project to the tip side from the tool main body 2 by a prescribed length.
