The invention refers to an injection device comprising a housing (10 340 410), a dose setting member (60, 80 350 420, 440) being operable in a first direction to set a desired dose to be dispensed, and a piston rod (30 530) being adapted to cooperate with a piston so as to cause a set dose to be injected from a cartridge (170). Further, a first part (123 300 480) and a second part (114 310 490) of the injection device are provided, which are adapted to perform a relative rotational movement with respect to each other during dispensing of a dose, and which are adapted to provide a non-visual feedback signal to a user only at the end of dispensing of a set dose. The dose setting member (60, 80 350 420, 440) is further operable in a second direction which is opposite to the first direction to cancel a set dose. A third part (100 212 320 460) is movable between a dose setting or cancelling position and a dose dispensing position relative to the first part (123 300 480) and/or the second part (114 310 490), which third part (100 212 320 460) contacts the first part (123 300 480) and/or the second part (114 310 490) in its dose setting or cancelling position or in its dose dispensing position.本發明有關於一種注射裝置,其係包括:一殼體(10;340;410),可在第一方向操作以設定待分配之一所欲劑量的一劑量設定構件(60,80;350;420,440),以及一活塞桿(30;530),其係適合與一活塞合作以便造成由一匣盒(170)注射出一設定劑量。此外,提供該注射裝置的第一部件(123;300;480)與第二部件(114;310;490),彼等適合在分配一劑量期間相互進行一相對旋轉運動,以及適合只在分配一設定劑量結束時提供一非視覺反饋信號給使用者。該劑量設定構件(60,80;350;420,440)更可在與該第一方向相反的第二方向操作以取消一設定劑量。第三部件(100;212;320;460)相對於該第一部件(123;300;480)及/或該第二部件(114;310;490)可在一劑量設定或取消位置與一劑量分配位置之間移動,該第三部件(100;212;320;460)在處於彼之劑量設定或彼之取消位置時或處於劑量分配位置時接觸該第一部件(123;300;480)及/或該第二部件(114;310;490)。100‧‧‧止動臂/第三部件102‧‧‧遠端面111‧‧‧中央孔口112、113‧‧‧凸緣114‧‧‧臂體115‧‧‧凹部120‧‧‧劑量指示器(數字套筒)122‧‧‧斜坡狀旋轉擋塊/零劑量擋塊接界123‧‧‧撓性臂體124、125‧‧‧凸起150‧‧‧回復彈簧
