The injection device additionally includes a drive member for driving one of the first and second gear members so as to cause the dynamic structure to move relative to the static structure along a predetermined direction due to the engagement between the first and second gear members. The injection device further includes a clutch mechanism for maintaining engagement between the first and second gear members in normal condition of the injection device, and for allowing disengagement of the first and second gear members upon a shock received by the injection device along the predetermined direction.
