Abstract A winged injection needle device includes an injection needle; a holder; a tube; a connector; a cylindrical stretchable member and a cylindrical protector. In this injection needle device, the stretchable member is stretched or contracted so as to slide said protector to change its position with respect to the injection needle within a range including a position in which the tip of the injection needle is completely contained in the protector, whereby an exposed length of the injection needle exposed from the protector can be changed into a desired length. The stretchable member itself can maintain a certain stretched or contracted state.
