To provide an automatic carrying vehicle for a roll body capable of preventing the roll body from moving in an axial direction or from being changed in a bamboo shoot shape while traveling.

Each of a pair of support bodies 13 of a support means 8 for loading and supporting the roll body comprises a contact surface which movably loads and supports a core a in the axial direction and which is positioned along the side surface of the sheet member b of the roll body supported by the support means 8. By operating the pair of support bodies 13 so as to be moved away from and close to each other by a drive means while the supporting member 8 supports the roll body, the support means can be changed over between a separated state in which the side surfaces of the sheet members b are separated from the contact surfaces of the pair of support bodies 13, respectively, and a contact state in which the side surfaces of the sheet members b are brought into contact with the contact surfaces of the pair of support bodies 13, respectively.
