ABSTRACT:
A safer safety door, provided at low cost and imposing little burden on an operator. A primary safety door with a top and a secondary safety door are provided on a clamping unit. The primary safety door and the secondary safety door abut each other at abutting portions provided on each safety door. The secondary safety door has an engaging member that swings along a guide member. The engaging member has a hinge bent in one direction. When both safety doors are closed, the primary safety door can be freely opened and closed independently. When the secondary safety door is opened, both safety doors are linked together and move as a single body. In the state where the primary and secondary safety doors are opened separately, when the primary safety door is moved to be closed, the hinge member bends and both safety doors are linked together as a unit.
