The present disclosure is configured to be received by a linearly displaceable drug delivery member cover (7), an actuator sleeve (11), and an actuator sleeve (11) in the administration mechanism (9) for the drug delivery device (1). As an actuator 13, the drug delivery member cover 7 displaces the actuator sleeve 11 relative to the actuator 13 by axially displacing the actuator sleeve 11 from its initial position to a displaced position. The rotor 13 is configured to be, and has a guide structure, a rotor 25 configured to be received by the actuator 13, and received by the rotor 25 to engage the rotor 25. As the configured plunger holder 21, the rotor 25 and the plunger holder 21 are configured to be deflected in the proximal direction, the plunger holder 21 and the plunger holder 21 at an initial position of the actuator sleeve 11 It is accommodated by and is configured to engage the plunger holder 21, and includes a plunger rod 23 configured to be deflected in the proximal direction, the actuator 13 being in the initial position of the actuator sleeve 11 plunger holder 21 In engagement with, the plunger holder 21 is configured to prevent displacement in the proximal direction with respect to the actuator 13, and the actuator 13 is driven by the displacement of the actuator sleeve 11 toward the displaced position. Disengaged from engagement with 21, is configured to enable proximal displacement of plunger holder 21, plunger rod 23 and rotor 25 relative to actuator 13, whereby actuator 13 is The dosing mechanism 9 configured to engage the guiding structure of the rotor 25 and rotate the rotor 25 relative to the plunger holder 21 to release the plunger rod 23 from the plunger holder 21. ).본 개시는 약물 전달 장치(1)를 위한 투여 메커니즘(9)에 있어서, 선형적으로 변위가능한 약물 전달 부재 커버(7)와, 액추에이터 슬리브(11)와, 액추에이터 슬리브(11)에 의해 수용되도록 구성된 액추에이터(13)로서, 약물 전달 부재 커버(7)는 액추에이터 슬리브(11)를 초기 위치로부터 원위방향으로 변위된 위치로 축방향으로 변위시켜서, 액추에이터(13)에 대해 액추에이터 슬리브(11)를 변위시키도록 구성되는, 상기 액추에이터(13)와, 안내 구조체를 갖고, 액추에이터(13)에 의해 수용되도록
