1. An injection device comprising an elongate housing having a central axis and a cap provided at a distal end of the housing, the cap being removable from the housing, the injection device comprising a syringe received in the housing and comprising a needle shield, the cap comprising:
an outer member for a user to grip when removing the cap from the housing;
an intermediate member disposed substantially within the outer member, at least one of the intermediate member and the outer member being rotatable relative to the other of the intermediate member and the outer member; and
an inner member disposed substantially within the intermediate member, the inner member being coupled to at least one of the outer member and the intermediate member, the inner member being configured to engage the needle shield of the syringe when the syringe is in the housing such that the inner member and intermediate member are removable together with the needle shield,
wherein the injection device further comprises a lifting mechanism configured to reduce a force required to remove the cap and the engaged needle shield from the housing, the lifting mechanism comprising at least one axially-inclined portion in engagement with at least one lifting portion such that rotational movement of the outer member or the intermediate member is converted into an axial movement of the inner member in a distal direction from the housing, wherein the intermediate member comprises one of the axially-inclined portion and the lifting portion.
