    摘要： A vacuum gate valve device for opening and closing a vacuum path includes a valve casing (60) with a valve body (30,40) provided in the valve casing, the valve body being allowed to reciprocate between two positions to close and open the vacuum path. A bonnet flange (9) closes the casing and a driving means (10) is provided on the bonnet flange for reciprocally driving the valve body. The driving means (10) has a stem shaft (3) which is loosely inserted into a through hole (11) of the bonnet flange and is coupled with the valve body. A member (4) isolates a sliding portion of the driving means from the vacuum path.
