The sheath (5) includes an opening of housing the cannula (2); a cannula fixing part of locking the cannula (2) housed in the opening; an attachment part of rotatably supporting the sheath (5) attached to the hub (1) or the collar (3); and a protrusive stopper which a user pushes by a finger to pivot the sheath (5) thereby to house the cannula (2) in the opening of the sheath (5). Herein, the stopper is arranged at a vicinity of a central portion of the sheath (5) in a longitudinal direction at the opposite side of the aperture of the opening, or arranged at a portion closer to a distal end side than the central portion of the sheath (5).</p> |
