Claim:
An injection apparatus with an end position-blocked dosing setting member, said injection apparatus comprising: a) a casing; b) a conveying means for delivering a selected product dosage; c) a dosage setting member which rotates in order to select said product dosage and can perform a rotational movement in a first rotational direction to an end position and in an opposite, second rotational direction relative to said casing, said dosage setting member coupled to said conveying means such that when activated, the conveying means delivers the product dosage selected by said dosage setting member; d) a dosing and activating element that can be rotated about and linearly shifted along a longitudinal axis, wherein the dosing and activating element extends beyond the casing and comprises a cylindrical section surrounding at least part of the conveying means, and wherein the dosing and activating element protrudes into the dosage setting member; e) and a rotational block which comprises at least one rotational stopper and at least one rotational counter stopper one of which is associated with the casing and the other is formed by the dosage setting member; f) wherein said rotational stopper and said rotational counter stopper abut against each other in the end position in said first rotational direction to prevent the dosage setting member from rotating in the first rotational direction beyond the end position.
