構。[Claims for Utility Model Registration] A housing having a grip portion and having a cylindrical injection portion for ejecting a stopper at the lower part thereof, and a housing that is housed in the housing so as to be able to reciprocate in the vertical direction, and a lower portion of the housing. a movable cylinder biased by a spring; a striking piston that is housed in the movable cylinder so as to be able to reciprocate in the vertical direction and that is integrally formed with a striking driver that is slidable within the injection section; an automatic switching valve mechanism that selectively connects the interior of the movable cylinder to a supply source of driving compressed air and the atmosphere as the movable cylinder reciprocates; A repetitively actuated impact tool comprising a contact member provided in the housing and a trigger mechanism that operates the automatic switching valve by operating a contact lever provided so as to be manually operable, wherein a part of the contact member is inserted into the housing. The contact member is placed so as to face the lower end surface of the movable cylinder, and the entry portion, which has moved upward relative to the housing when the lower end of the contact member is pressed against the surface of the material to be driven, is placed under the movable cylinder. By bringing it into contact with the end surface,
A recoil absorption mechanism for a repetitively actuated impact tool, characterized in that the movable cylinder is supported in a separated manner.
