Abstract: An automatic culture device which employs closed-system culture vessels and in which, when a passage part (2) and a rotational valve mechanism (3) are configured, the multiple culture vessels in a culture vessel part (1) can be rendered equal in liquid-feeding conditions by, for example, regulating the length of each passage. As a result, the evenness in quality of cells incubated in the multiple culture vessels is rendered possible. Furthermore, by providing a mechanism which enables a user to normally set passages in the device, the evenness in quality of the cells is rendered possible likewise.
