A pause mechanism for a drive assembly of a medicament delivery device

A drive assembly of a medicament delivery device, the drive assembly comprising:

• a driver configured to be rotationally driven by a power source;
• an actuator sleeve;
• and
• a blocking structure positioned radially between the actuator sleeve and the driver when the actuator sleeve is in a first position, wherein the blocking structure is configured to engage with the driver when the actuator sleeve is in the first position such that the rotation of the driver relative to the blocking structure is prevented,
• wherein when the actuator sleeve is moved from the first position towards a second position the actuator sleeve is configured to release the blocking structure from the driver, enabling the driver to rotate,
• wherein the drive assembly further comprises a resilient member operably connected to the actuator sleeve and is configured to be tensioned by the actuator sleeve when the actuator sleeve is moved from the first position to the second position, and
• wherein when the actuator sleeve is moved from the second position to the first position by the resilient member the blocking structure is re-engaged with the driver.
