Document Type and Number:

Japanese Patent JP2007211762

Kind Code:

A

Abstract:

To cut off a leaked magnetic flux leaking from an activation device to the outside by magnetism.

A magnet train is formed linearly so that the magnetic poles of the main magnetic flux surfaces of the adjacent permanent magnets among a plurality of permanent magnets are different from each other. The magnet train is attracted on the steel plate made of a ferromagnetic material.
