The invention refers to a dispensing speed control mechanism for use in an injection device having a release button (71), which is displaceable to initiate dispensing of a set dose, a first component part (42), which is driven by a power reservoir (90) during dose dispensing, and a second component part (12), which is stationary during dose dispensing. The speed control mechanism comprises friction means (120) for retarding the first component part (42) during dose dispensing depending on the position of the release button (71). Further, the invention refers to a handheld injection device with such a speed control mechanism.
