The present application relates to shock absorbers for injection devices. According to a first aspect, this specification discloses an injection device comprising: a medicament container; a stopper translatably disposed within the medicament container; and a plunger rod comprising: a plunger rod body; and a shock absorber, wherein the plunger rod is operable to displace the stopper; and wherein the shock absorber contacts the stopper during displacement of the stopper by the plunger rod, thereby reducing an impact force between the plunger rod and the stopper. 本申请涉及用于注射装置的缓冲器。根据第一方面，本说明书公开了一种注射装置，所述注射装置包括：药剂容器；塞子，所述塞子可平移地设置在所述药剂容器内；以及柱塞杆，所述柱塞杆包括柱塞杆本体和缓冲器，其中，所述柱塞杆可操作以使所述塞子移位，并且其中，在由所述柱塞杆使所述塞子移位的过程中，所述缓冲器接触所述塞子，由此减小在所述柱塞杆与所述塞子之间的撞击力。
