Abstract:
1. A fastener driving tool comprising: a housing; a trigger supported to the housing; a push lever supported to the housing and movable between an upper dead center and a lower dead center in a moving direction, a fastener driving operation being performable when both of a pulling operation for pulling the trigger and a pressing operation for pressing the push lever against a workpiece are executed; a valve comprising: a rigid member configured to move the valve member to separate the valve member from the engaging part when the push lever moves from the lower dead center to the upper dead center; a resilient member configured to provide a resilient force to move the valve member to separate the valve member from the engaging part when the push lever moves from the lower dead center to the upper dead center, the resilient force being changeable in accordance with a movement of the push lever; and a switching part selecting one of the rigid member and the resilient member to move the valve member to separate the valve member from the engaging part, wherein, when the switching part selects the rigid member, the fastener driving operation is performed regardless of an order of the pulling operation and the pressing operation, and, when the switching part selects the resilient member, the fastener driving operation is performed only when the pulling operation is executed after the pressing operation is executed.
