Abstract

It is an object to provide a press apparatus, where when a passive cam (6) to which a processing member such as a punch (5) was mounted is repaired, removal of the passive cam (6) from a bottom force is made to be easy, and workability is improved.
A press apparatus has an actuation cam in a top force, a passive cam (6) in a bottom force which is contact-pressed and driven by the actuation cam and to which a processing member such as a punch (5) is mounted, a guide base (7) in the bottom force for sliding and guiding the passive cam, guide posts (8) which are mounted across the guide base (7) and move so as to slide the passive cam (6) and force applying means for applying a force to the passive cam (6) towards an opposite-work side. In such a press apparatus, the passive cam (6) is fitted into the guide base (7) so that when the guide posts (8) which were mounted across the guide base (7) are drawn out, the passive cam (6) can be lifted up and dismounted.
