Abstract:
To provide a lifter device that adjusts the height of a seat by a rotation drive mechanism and a lock mechanism on the basis of an operation of an operation handle, the lifter device being designed such that a pole operation member in the lock mechanism is directly aligned with a reference position with respect to a support member without interpolation of other components, thereby aligning the pole operation member with the support member highly accurately without requiring an increase in dimensional accuracy of components that would be interposed.SOLUTION: A pole operation member 37 comprises a projection 37a projecting on an outer peripheral side for rotational alignment. A support member 23 has a second projection 38 projecting opposite the projection 37a in order to serve as a reference position, in a rotating direction, for the pole operating member 37. The projection 37a and the projection 38 are provided with a ring spring 62 that is urged such that the projection 37a coincides with the projection 38 in the rotating direction of the pole operation member 37 while an operation handle is not operated.SELECTED DRAWING: Figure 9
