<p>PROBLEM TO BE SOLVED: To provide a valve timing adjustment device in which oil leakage can be suppressed.SOLUTION: A valve timing adjustment device 10 includes a vane rotor 40 which has a laminate 50 and a resin member 60. The laminate 50 comprises a plurality of metal plates 201-210 which are laminated in an axial direction. The resin member 60 is formed of a resin molding the laminate 50, and has a first side wall part 62 which is positioned between a sprocket 11 and the laminate 50 facing each other in the axial direction and can slide on the sprocket 11 and a second side wall part 63 which is positioned between a bottom part 26 of a housing 20 and the laminate 50 facing each other in the axial direction and can slide on the bottom part 26. Even when the axial dimension of the laminate 50 varies between individuals, variance in axial dimension of the vane rotor 40 can be suppressed by adjusting axial dimensions of the first side wall part 62 and second side wall part 63 of the resin member 60 in resin molding.</p> |
