Zusammenfassung:	PROBLEM TO BE SOLVED: To ensure safety by effective operation of a stopper irrespective of change of a position in the case of a mold thickness regulation by interposing an operating member of a link between a safety door and the stopper side. SOLUTION: A safety bar 6 in which engaging steps 7 and tapered surfaces 8 are alternately formed at a predetermined interval at an end with the surfaces 8 directed outward is provided over a movable board side fixed at its rear end and a pressure reception board 2. An end 10a bent to an upper part of the bar 6 of a support block 9 protruding from a side of the board 2 is directed to the movable board side and outside, and a lever member 10 is rotatably laterally supported. A stopper 11 engaged from a side with the steps 7 of the bar is longitudinally mounted at a rear end of the member 10 to outside of a bearing. An operating member 15 is constituted by a pair of link arms 13 at a predetermined interval rotatably clamped at a seating plate 12 and a link bar 14 pin-coupled to both ends of the arms 13 and laterally oscillatorily installed. The bar 14 is disposed at a lower side of the end 10a of the member 10, and the member 15 is mounted with laterally long length in an upper guide frame of a safety door 5.
