形成される ことを特徴とする穿孔装置。[Claim for Utility Model Registration] A movable body that cooperates with a punch pin, and a coil disposed within an outer frame having an inner periphery with a substantially circular cross section, and when the coil is energized, a magnetic flux that attracts the movable body is generated. In the drilling apparatus, the movable body includes a generally disk-shaped disk portion that moves inside an outer frame of the yoke, and a spring that applies a force to the movable body in a direction opposite to the suction. 1. A punching device characterized by being formed from a flange facing an end surface of an outer frame of a yoke and having substantially the same shape as the end surface.
