ABSTRACT:
When a slide member mounted with a tool reciprocates on a guide member reach one end and the other end positions of the guide member, permanent magnets provided on the guide member and the permanent magnets provided on the slide member repel each other to give the guide member forces for reversing its moving direction. The guide member is provided to be movable with respect to a base and repulsive forces between permanent magnets provided on the base and permanent magnets provided on the guide member are used to retain an axial position of the guide member.
