Abstract
In an injection device a rotary indicator element (20) indexes angularly between a pre-firing position to an injection complete position to create a visual and audible/tactile signal as the drive plunger (28) arrives at or near its fired position. The indicator element (20) has a saw tooth profile which co-operates with respective abutments (34, 40) on the plunger and a housing part of the device to control and energize indicator movement.
