[Problem] To provide: a bearing unit that is capable of preventing a reduction in pressurization precision, damage to structural members, etc., without excessive force being placed on rolling bearings, a pressure roller, etc., due to thermal expansion of the pressure roller; a press device that is provided with said bearing unit; and a laminated assembly manufacturing device for manufacturing laminated assemblies obtained by applying bonding pressure to a film material after said film material has been laminated. [Solution] A bearing unit (10) is provided with: rolling bearings (11, 12) that rotatably support a rotating shaft (33); an inner box (13) that rotatably supports the rotating shaft (33) of a pressure roller (30) via the roller bearings (11, 12); and an outer box (14) that is disposed on the outside of the inner box (13). An inner surface (14a) of the outer box (14) slidably mates with an outer surface (13a) of the inner box (13) in the axial direction of the rotating shaft (33). The inner box (13) is capable of moving in the axial direction of the rotating shaft (33) relative to the outer box (14). |
