The utility model provides a manufacturing device of an elastic lamination body. A driving mechanism (20) comprises synchronous belts (25) fixed with guiding plates (19), a plurality of synchronous belt wheels (26) for hanging the synchronous belts (25) in annular paths (T1) including moving paths (E1), motors (28) for sequentially driving the synchronous belt wheels (26) to rotate in positive and negative directions in a manner of enabling the guiding plates (19) to reciprocally move in the moving paths (E1), and sliding blocks (29) and rails (30) for allowing the guiding plates (19) to move in the moving paths (E1) corresponding to one pair of pressure rollers (5) and limiting the guiding plates (19) to move in a direction perpendicular to the moving paths (E1) corresponding to the pair of pressure rollers (5). Therefore, elastic members can be stably positioned corresponding to two piece bodies.
