A device for adjusting a position of two film rolls so as to align the two film rolls with each other in laminators is disclosed. A shaft holder engages with one end of a housing and movably receives one end of a roll shaft. A connection bolt, having a head and an externally-threaded shank provided with a woodruff key, engages with the other end of the housing from the inside to the outside of the housing, with the head being positioned inside the housing and the shank partially projecting from the housing. A bearing is set in the head of the connection bolt and holds the roll shaft passing though the shaft holder. An annular setting lever engages with the shank of the connection bolt at a position outside the housing. An adjusting handle is fitted over the woodruff key of the connection bolt. The above handle has a radial screw hole, with a wrench bolt being movably screwed into the screw hole so as to removably fix the handle to the woodruff key of the connection bolt.
