Abstract: Under a state where the zipper 22 of a culture bag is opened, an operator depresses the opening button 43 of an arm 40 with one finger. Consequently, a force for oscillating the arm 40 to separate a retaining portion 49 upward from the culture surface 32 around a pin 42 acts against the urging force of a leaf spring 50. Consequently, the tip 52a of an extended portion 52 ascends to a predetermined position while resisting against the urging force of the leaf spring 50. Since the lower surface 20a of the culture bag 20 is retained by a base 31 and the upper surface 20b is raised upward by the tip 52a of an extended portion 52, opening 24 of the culture bag 20 is widened. Since the width of the base 31 is larger than that of the arm 40, upper space of the culture surface 32 is not occupied by the arm 40 and a sufficiently wide work space is provided in the culture bag 20.
