To assemble heat affected member to axis of rotation welded/combined of a seat hinge mechanism adequately.SOLUTION: A seat hinge mechanism 10 includes a stem 11 which is fixed to a floor F, a movable part 12 which is fixed to a seat, a rotation shaft 13 which is welded to the movable part 12 by passing through the movable part 12 and the stem 11 and simultaneously is supported to the stem 11 in manner of being capable of rotating, a spiral spring 14 which actuates rotation urged force to the movable part 12 by passing through the axis of rotation 13 and an oil damper 15 which is a heat affected member which queues with the spiral spring 14 in an axial direction by passing through the axis of rotation 13. The rotation shaft 13 is split into a first shank 13A which is welded to the movable part 12 and a second shank 13B which is welded to the movable part 12 by queuing to one side of the first shank 13A in the axial direction. The first shank 13A includes a leg 13A3 which is capable of setting by passing through the oil damper 15 from one side in a weld state to the movable part 12 and a non-weld state of the second shank 13B.SELECTED DRAWING: Figure 4
