PROBLEM TO BE SOLVED: To provide a tightener-pushing device capable of appropriately preventing the leakage of oil in a chain case. SOLUTION: This tightener-pushing device 30 is equipped with a bolt-receiving body 41 fitted with the inner circumferential side of an opening part 40 of the chain case 16, and the bolt-receiving body 41 having a screw thread part 44 and circumferential groove part 45 for a packing on its inner circumferential surface. At the screw thread part 44 of the bolt-receiving body 41, a bolt body 51 pushing the tightener toward the chain side is screw-threaded. In the circumferential groove part 45 for the packing of the bolt-receiving body 41, a packing body 60 for preventing the oil in the chain case 16 from leaking from a gap between the bolt-receiving body 41 and the bolt body 51, is arranged.
