摘要： PROBLEM TO BE SOLVED: To compactly incorporate an idle driving prevention mechanism in a driving tool having a sequential mechanism because of the conventional difficulty of disposing both mechanisms compactly side by side since it is necessary to provide durability against an excessive pulling operation force by increasing the thicknesses of a switch lever and its peripheral member in order to add an idle driving prevention mechanism by locking the pulling operation of the switch lever, in a driving tool having a so-called sequential mechanism.SOLUTION: An idle driving prevention configuration which enables a switch lever 5 to perform a pulling operation but causes the lever to perform idle driving to invalidate the pulling operation is employed. By the idle driving of the switch lever 5, an idle driving prevention mechanism K that needs no durability like the conventional tool is compactly placed side by side with a sequential mechanism S.

摘要： Bei einem Eintreibwerkzeug, bei welchem ein Eintreibvorgang unter der Bedingung ausgeführt werden kann, dass sowohl ein Drücker als auch ein Kontaktarm ein-betätigt sind, ist es notwendig, dass, wenn das Eintreibwerkzeug mit dem Drücker ein-betätigt getragen wird, ein ungewollter Eintreibvorgang nicht auftritt, auch wenn der Kontaktarm andere Bauteile berührt. Ein Eintreibwerkzeug, das einen konventionellen, elektrisch gesteuerten Zeitnehmer aufweist, kann nicht bei einem Umstand verwendet werden, bei welchem keine elektrische Leistung zugeführt werden kann. Bei der vorliegenden Erfindung kann eine Zeitnehmersteuerung erzielt werden, auch bei einem Umstand, bei welchem keine elektrische Leistung zugeführt werden kann. Nachdem ein Drücker (12) ein-betätigt ist, startet ein Kontakteinschränkungsbauteil (21) sich zu einer Verriegelungsseite zu drehen, während ein Drehwiderstand demselben durch ein Drehwiderstandsaufbringungsbauteil aufgebracht wird. Ein Verriegelungsbereich (21e) tritt in einen Verriegelungsaufnahmebereich (6c) zum Verhindern einer Ein-Betätigung eines Kontaktarms (6) ein, nachdem eine Referenzzeit t nach der Ein-Betätigung des Drückers verstrichen ist. Demzufolge kann ein ungewollter Eintreibvorgang verhindert werden. Ein Zeitnehmermechanismus (20) weist nur eine mechanische Konfiguration auf, die es einer Zeitnehmersteuerung ermöglicht, bei einem Umstand, bei welchem keine elektrische Leistung zugeführt werden kann, ausgeführt zu werden.
