A power pack assembly for a medicament delivery device, the power pack comprising a plunger rod () extending along a longitudinal axis (L) and having a proximal and an opposite distal ends, an actuator () provided with a holding element () and configured to interact with a corresponding holding element on the plunger rod (), a first force element () arranged to exert a force on the plunger rod; an actuator sleeve mechanism () arranged to releasably lock said holding element () in engagement with the corresponding holding element of said plunger rod () such as to hold said first force element () in a tensioned state. The invention is characterized in that said actuator sleeve mechanism () comprises an actuator cap () configured to hold said holding element () in engagement with the corresponding holding element of said plunger rod () and an actuator sleeve () interconnected with said actuator cap () such that in relation to the actuator (), said actuator cap () is moved a shorter distance than the actuator sleeve () when said actuator sleeve is distally displaced in relation to the distal housing part.

A wheelchair including a seat body and at least one wheel module disposed at a bottom of the seat body is provided. The wheel module includes a motor, at least one wheel, and a transmission unit coupled between the motor and the wheel. The transmission unit has at least one one-way bearing. The motor outputs a first rotating moment and a second rotating moment with opposite directions to the transmission unit. The one-way bearing transmits one of the first rotating moment and the second rotating moment to the wheel to drive the wheel to roll, such that the seat body is in linear motion, or so the wheel module rotates relative to the seat body in the directions of the first or the second rotating moments. The shafts of the first and the second rotating moments are perpendicular to the rotating shaft of the wheel.
