To prevent a guide means from deviating upward in a guide structure by means of the guide means having a plurality of rolling elements between a bush and a post.
In the guide device, the post 3 of a die holder 1 and the bush 4 of a punch holder 2 are slidable to each other via the guide means 5. In the guide means, the plurality of rolling elements are held by a cylindrical holding body 7 in a rolling manner. A stepped cylindrical spacer member 9 and a spring 8 on the outer side thereof are interposed in the post. The spring is abutted on a stepped part of the spacer member, and the spacer member faces the bush. At the top dead center, an upper end of a large diameter part 11 urged by the spring is abutted on a lower end of the bush, a space is generated between a lower end of the guide means and an upper end of a small diameter part 10, and the lower end of the small diameter part 10 is not brought into contact with a template 1 at the bottom dead center. The spring force is not applied to the guide means, and the guide means is less easily shifted during the pressing.
