Zusammenfassung:	PURPOSE:To enable favorable molding by avoiding defective molding, by providing a material holding device preventing a slide of a molding material on a tilted mold surface of a bottom force. CONSTITUTION:The subject mold is made into structure where a plurality of pins 7 are provided freely projectably and retreatably through a tilted mold surface 4 of a bottom force 2 by a cylinder 6, the pin 7 is thrusted into a flexible molding material 1 put on the tilted mold surface 4 and the molding material 1 is held. Then the pin 7 is ejected after the molding material 1 is put on the titled mold surface 4 or before the same is put on the same and the pin 7 is held by thrusting the same into the molding material and then molding is performed by lowering a top force. Then the pin 7 is lowered at the time of molding and shunted.
