PROBLEM TO BE SOLVED: To provide a connecting mechanism which exhibits a kick-up function stable for a long period. SOLUTION: One cam 2 is mounted on a main frame 20 side and another can 7 is mounted on a sub-frame 27 side. Both cans 2 and 7 are freely turnably connected by thrusting members 14 and both cams 2 and 7 are thrust by the thrusting members 14 in a direction where both approach each other. When both cams 2 and 7 exist in a meshed state, the sub-frames 27 are held in the meshing positions by cooperation of both cams 2 and 7 and the thrusting members 14. When the sub-frames 27 are turned, the meshing positions of both cams 2 and 7 are changed and at this time, the sub-frames 27 are kicked up in the direction where the sub-frames part from the main frame 20 or kicked down in the direction where both approach each other by the cooperation of both cams 2 and 7 and the thrusting members 14.
