1. A needlepoint-covering member for covering the needlepoint of the injection needle comprising a needle having a sharp needlepoint and a needle hub provided at the end of the needle far from the needlepoint for being joined with the cylinder, comprising:

  • a plate member whose end is fixed to the needle hub side and which can be bent to less than half of the axial length in the extended state in order to maintain the state before covering; and

    a covering portion for covering the needlepoint when the bent plate member is extended;

    wherein the plate member has a length to allow the covering portion to reach the position of the needlepoint when extended; and

    is widthwise concaved toward the needle for resisting external forces that tend to remove the covering portion that covers the needlepoint from the needlepoint.
