A grease supply mechanism is provided inside a vacuum transfer chamber. The grease supply mechanism includes: a grease storage part in a bottomed cylindrical shape storing grease therein; and a movable cover covering an opening of the grease storage part and sliding while being in contact with an inner wall of the grease storage part. When the cover is pressed and moved, the grease is supplied into a grease inlet via a grease supply port.
