Abstract

Provided is an injection needle cartridge (1) comprising a needle holder (5) having an injection needle (11) held therethrough in the axial direction, a latch ring (4) for holding the needle holder (5) such that a latch portion (42) is elastically deformed to open to the radially outer circumference side, and a housing (10) for regulating the retraction of the latch ring (4) at a regulation position located on the axially forward side of an initial position and for holding the latch ring (4) and the needle holder (5) so as to regulate the relative rotation of the needle holder (5) in at least an initial position. The needle holder (5) can be moved forward, when it moves for use axially of the housing (10), while being followed by the latch ring (4), to the regulation position, and is axially extracted, when it moves back axially to the initial position, from the latch ring (4) regulated at the regulation position.
