Abstract
An injection needle assembly includes: a needle tube; a needle hub holding the needle tube; a protector movable between a first position at which a needle tip of the needle tube is covered and a second position at which the needle tip of the needle tube is exposed; a biasing member configured to bias the protector toward the needle tip of the needle tube along an axial direction; a retaining member that supports the protector such that the protector is movable along the axial direction, wherein an abutment piece of the protector abuts on the retaining member when the protector is moved to the first position; and a restriction mechanism configured such that, after the protector has moved from the first position to the second position and back to the first position, the restriction mechanism restricts the protector from moving from the first position to the second position again.
