Abstract

PURPOSE: To cause to fall forcibly an object attracted by coupling a releasable member and a ball piece-fixing plate so as to move relatively, and projecting the releasable plane of the releasable member from the attractive plane of the ball piece by the transfer of the releasable member.
CONSTITUTION: When the attractive plane of a ball piece 6 positions in the same plane with or higher than the releasable plane of a releasable member 8, an object to be attracted is attractively and strongly fixed to the ball piece by the magnetic flux from the ball piece 6. If the releasable member 8 is moved in the direction of an arrow, the releasable plane of the releasable member 8 projects from the attractive plane of the ball piece 6 because the ball piece and a fixed plate 3 is connected by a screw thread. The projection press the object, and the object is forcibly caused to fall.
