Described is an injection device (1) for administering a dose of a medicament (M) comprising a carrier (7) adapted to contain a syringe (3) having a hollow injection needle (4) and a stopper (6), a drive spring (8), a plunger (9) adapted to forward load of the drive spring (8) to the stopper, and a noise component (28) adapted to generate an audible and/or tactile feedback by impacting a component of the injection device (1) when the stopper (4) is located at a proximal end of the syringe (3). In a first state, a resilient arm (30) on the plunger (9) is maintained in engagement with the noise component (28) by the carrier (7). In a second state, the arm (30) disengages the noise component (28) and deflects at least partially into an aperture (7.22) in the carrier (7). |
