Pressure device, battery module manufacturing device, and manufacturing method

A pressing apparatus for pressing a plurality of battery cells, the pressing apparatus comprising:

• a pressing jig including a support plate, and a plurality of pressing rods respectively disposed on a first side of the support plate and located to respectively face the plurality of battery cells, the plurality of pressing rods being configured to respectively press the plurality of battery cells and to adjust to some of the plurality of battery cells that are not level during pressing;
• and
• a transfer unit disposed on a second side of the support plate and having a transfer jig configured to transfer the support plate towards the plurality of battery cells,
• wherein each of the plurality of pressing rods includes a pressing portion,
• wherein the pressing portion includes an elastic member configured to be elastically deformed in a direction opposite to a pressing direction, when a corresponding battery cell is pressed, and
• wherein the elastic member is positioned at a part of the pressing portion pressing the corresponding battery cell so as to press the corresponding battery cell directly.
