Provided is a safety needle assembly for protecting a needle point, a safety type needle assembly having a curved portion, to which an erroneous piercing preventing mechanism is added, or a safety type Hoover needle assembly thereby to prevent the piercing accident. The safety needle assembly comprises a needle having a point at its leading end, a hub for holding the root end portion of the needle, and a leading end protecting portion. The safety needle assembly is characterized by further comprising a restricting portion for restricting the distance between the needle and the hub, in that the leading end protecting portion includes a mechanism for warping the needle point, when the leading end protecting portion moves the leading end of the needle to a projecting position, thereby to accommodate the needle point in the inner side of the leading end protecting portion, so that the leading end of the needle is protected.
