Abstract
A fastener feeding mechanism in a fastener driving device is provided for feeding fasteners from a fastener support rail formed in a magazine to a fastener drive track formed in a driver guide for reciprocal movement of a driver and connected to a forward portion of the fastener support rail. The fastener feeding mechanism includes an operation member operable by an operator and slidably movable in a longitudinal direction of the fastener support rail. A biasing mechanism biases the operation member in the forward direction of the fastener support rail. A pusher is movable in the longitudinal direction of the fastener support rail and includes an abutting portion for abutting on the rear end of a row of the fasteners. The abutting portion is movable between a first position within the fastener support rail and a second position away from the fastener support rail. An interlocking mechanism is provided between the operation member and the pusher for permitting movement of the pusher together with the operation member and for moving the pusher in such a manner that the abutting portion moves from the first position to the second position according to movement of the operation member …
