Abstract:
The present invention relates to a plunger capable of moving back and forth and a medicine injection device including same, in which, by manually or automatically moving the plunger backwards, user convenience may be provided. In addition, according to the present invention, when a rotation unit (20) is no longer rotated, first flat portions (151-1, 151-2) of a first adjusting portion (150-1) and a second adjusting portion (150-2) are slid in an inclined direction, that is, in a direction from a second housing (120) to the rotation unit (20), respectively along a first inclined portion (121) and a second inclined portion (122), so that the first adjusting portion (150-1) and the second adjusting portion (150-2) are spaced apart from each other, and thus a pushrod unit (10) can be moved in a direction of the rotation unit (20), that is, backwards.
