Abstract
A safety mechanism syringe includes a syringe, a needle, a holder, and a needle cover displaceable relatively with respect to the syringe along an axial direction of the syringe from a use position toward a protection position. The holder includes a locking portion. At least one member of the holder and the needle cover includes a protruding portion that protrudes toward the other member, and the other member includes a restriction portion that abuts on the protruding portion to restrict relative displacement of the needle cover with respect to the syringe along the axial direction of the syringe from the protection position toward the use position.
