초록 ▼

A mechanism is provided for removing a jammed fastener from a fastener drive track formed in a driver guide of a fastener driving device through an opening formed in the fastener dive track. The fastener driving device includes a driver reciprocally driven by a driving source to drive fasteners fed into the fastener drive track. The mechanism for removing the jammed fastener includes a movable member for closing the opening of the fastener drive track. A connecting mechanism connects the movable member to the drive guide to such a manner that the movable member is movable relative to the drive guide between a first position for closing the opening and a second position for opening the opening. An engaging mechanism is provided for engaging the movable member with the driver guide so as to keep the movable member at the first position. A first biasing mechanism biases the movable member in a direction to engage the same with the driver guide. The first biasing mechanism applies a biasing force to the movable member when the driver is driven by the driving source, while it is prevented from applying the biasing force to the movable member when the driver is not driven.
