RECLINING DEVICE AND METHOD FOR MANUFACTURING RECLINING DEVICE

摘要

A Taumel type reclining device is provided with an external gear and an internal gear oscillating and rotating relatively while changing the meshing position, at one and the other of the seat cushion and the seat back, and the angle of the seat back can be adjusted continuously. At least one of the outer surface of a small diameter tubular section and the inner surface of a large diameter circular hole constituting a space for inserting a pair of wedge members for regulating rotation formed in the center of the external gear and the internal gear is calibrated by having as reference an axis determined by three or more different external gear meshing positions in the circumferential direction of the external gear or three or more different internal gear meshing positions in the circumferential direction of the internal gear. Consequently, calibration precision of the tubular section or the circular hole in the external gear or the internal gear is enhanced and wobbling can be prevented while the device is being used.
