する釘打機における動作モード切換機構。 A striking piston that integrally combines a driver for striking a fixed tool such as a nail, a striking cylinder that slidably accommodates the striking piston, and a blowback chamber disposed around the circumference of the striking cylinder. a main valve that opens and closes to introduce and discharge compressed air into the striking cylinder; a manually operable trigger valve that controls the compressed air that opens and closes the main valve; a trigger valve that operates the trigger valve; In a nailer having a contact arm, a stem for engaging the contact arm is provided integrally with the piston that is moved forward by the increase in pressure in the blowback chamber, and a stem engagement hole is provided in the contact arm, so that when the trigger is in the ON state, the stem for engaging the contact arm is provided. The stem engages with the engagement hole to lock the contact arm in the ON state, and when the trigger is in the OFF state, the stem is separated from the engagement hole by a spring force, turning the contact arm into the OFF state. An operation mode switching mechanism in a nailing machine characterized by the following features.
