摘要：
602539 A piston rod assembly for a drug delivery device, comprising: a piston rod (200) adapted to be operably engaged with a piston of a cartridge containing a medicament, at least one adjusting member (202) displaceably disposed at the piston rod with respect to the piston rod's long axis, and being interconnected with a distal end section (206) of the piston rod, and at least one interlock means (216) adapted to interact with the adjusting member and/or with the piston rod for mutually locking in position the adjusting member and the piston rod in an arbitrary relative position in order to compensate for tolerances of manufacture and/or of assembly. The interlock means comprise at least one resiliently biased tongue member adapted to engage with a corrugated surface portion (208) of the adjusting member or of the piston rod.
