A transportation apparatus, comprising: a transportation roller used for transporting a medium and which includes plural rollers arranged in a rotation axis direction and a coupling portion for coupling an end portion of one of, among the plural rollers, two arranged adjacent to each other in the rotation axis direction to an end portion of the other, the adjacent two being defined as a first roller and a second roller, the coupling portion including, a first bearing that supports the end portion of the first roller rotatably; a second bearing that supports the end portion of the second roller rotatably; a fixing member to which the first bearing and the second bearing are fixed; and a joint portion provided between the first bearing and the second bearing in the rotation axis direction for connecting the end portion of the first roller to the end portion of the second roller, wherein each of the first roller and the second roller has a shaft portion located at its end in the rotation axis direction; and wherein the joint portion includes a cylindrical axial-hole-formed member that has an axial hole formed inside its inner cylindrical surface and a slit extending in the circumferential direction in its cylindrical portion such that the joint portion can connect the shaft portion of the first roller and the shaft portion of the second roller together in a state in which deviation of the axial center of rotation of the shaft portions with respect to the axial center of the first bearing and the second bearing is tolerated. a transportation roller used for transporting a medium and which includes plural rollers arranged in a rotation axis direction and a coupling portion for coupling an end portion of one of, among the plural rollers, two arranged adjacent to each other in the rotation axis direction to an end portion of the other, the adjacent two being defined as a first roller and a second roller, the coupling portion including, a first bearing that supports the end portion of the first roller rotatably; a second bearing that supports the end portion of the second roller rotatably; a fixing member to which the first bearing and the second bearing are fixed; and a joint portion provided between the first bearing and the second bearing in the rotation axis direction for connecting the end portion of the first roller to the end portion of the second roller, a first bearing that supports the end portion of the first roller rotatably; a second bearing that supports the end portion of the second roller rotatably; a fixing member to which the first bearing and the second bearing are fixed; and a joint portion provided between the first bearing and the second bearing in the rotation axis direction for connecting the end portion of the first roller to the end portion of the second roller, wherein each of the first roller and the second roller has a shaft portion located at its end in the rotation axis direction; and wherein the joint portion includes a cylindrical axial-hole-formed member that has an axial hole formed inside its inner cylindrical surface and a slit extending in the circumferential direction in its cylindrical portion such that the joint portion can connect the shaft portion of the first roller and the shaft portion of the second roller together in a state in which deviation of the axial center of rotation of the shaft portions with respect to the axial center of the first bearing and the second bearing is tolerated.
