An injection device includes a housing and a setting part configured to, in relation to said housing, rotate in a first rotational direction when an amount of injection fluid to be dispensed is being set. The setting part rotates in a second rotational direction counter to the first rotational direction when the injection fluid is pressed out of the injection device. A latching unit defines at least one latching position of the setting part and acts between the setting part and the housing. The latching unit is active at least when the amount of injection fluid to be dispensed is set and each of the latching positions has an unequivocal rotational position of the setting part in relation to the housing assigned thereto.
