CA 2609529

A driving tool has a magazine (5), a strike mechanism for ejecting a fastener, and a contact mechanism for effecting operation of a trigger. A first blank firing prevention lever (17) is horizontally swingable and is capable of coming out into a fastener feeding path (12) of the magazine. The contact mechanism has a lower arm (21) projectable from the tip of a nose section, an intermediate member (22) moving in association with the lower arm (21) and moving in association with the first blank firing prevention lever (17), and an upper arm (23) associated with the trigger. A second blank firing prevention lever (32) capable of engaging with the upper arm (23) is provided at the intermediate member (22). The intermediate member and the lower arm (21) are urged downward. When the intermediate member swings at the same time when the first blank firing lever (17) enters into the magazine and swings, the engagement between the second blank firing prevention lever (32) and the upper arm (23) is released.
