Claims

[Scope of utility model registration request]

A piston that is integrated with a driver that hits a stopper, etc., a cylinder that has the piston built in and is slidable, and a sleeve that is slidable in circumference of the cylinder and that functions as a valve that controls the inflow of compressed fluid into the cylinder. In a driving machine having a structure in which the driver is pushed up to start a strike and a stop is driven by repeating this strike many times, an attractive magnetic material is provided in a driving part for driving the stop. is arranged so that the stopper shaft part is attracted to the inside of the punching part so that the stopper does not fall off, and the head of the stopper is kept in non-contact with the inside of the punching part. A stopper holding device for a multi-impact driving machine, wherein a recess is formed so that the stopper can be held by suction in the same direction as the driving direction.
