摘要：
The invention relates to an auto injector (1) for administering a dose of a liquid medicament (M) comprising: an elongate case (12) arranged to be held by a user a tubular chassis (2) telescopable in the case (12) and biased against the case (12) so as to protrude from the case (12) a syringe (3) with a hollow injection needle (4) a drive spring (8) and a plunger (9) for forwarding load of the drive spring (8) to a stopper (6) of the syringe (3) a trigger button (13) which is initially abutted against the case (12) thus preventing actuation wherein the chassis (2) is arranged to translate into the case (12) against the bias when pressed against an injection site wherein the trigger button (13) is at least initially coupled to the chassis (2) in such a manner that the trigger button (13) emerges from the case (12) when the chassis (2) is being pressed against the injection site so as to allow actuation by being translated towards the case (12) for starting an injection cycle.
