The actuator comprises a housing in which the canister is received, and an actuating mechanism for actuating the canister. The actuating mechanism comprises a loading member which is fitted to or comprised in the body of the canister, an actuating member which is operable by a user to actuate the canister to deliver medicament, and a drive member which operably couples the loading member and the actuating member and is pivotally mounted, such as to be pivoted on operation of the actuating member to engage and drive the loading member from a first, rest position to a second, actuated position in which the canister is actuated. |
