A dual-shaft pivot device includes a resilient guide assembly composed of a plurality of resilient guide members and first and second pivotal shafts. Each resilient guide member has two accommodation portions at two ends thereof and a connecting groove communicating with the two accommodation portions. One end of the inner wall of each accommodation portion, far away from the connecting groove, has an end protrusion. The first and second pivotal shafts have middle portions which are inserted in the accommodation portions of the resilient guide member. Each middle portion has at least one middle flat surface to get contact with the end protrusion for the middle portion to push the end protrusion during turning to bring resilient deformation of each accommodation portion.
