Title:
DECELERATION DEVICE AND SEAT DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/083577
Kind Code:
A1
Abstract:
A deceleration device comprising first and second gears that have different numbers of teeth. A cam mechanism is disposed on the same axis as the first gear, engages the first gear with the second gear in a state of eccentricity, and moves the engagement position between the first gear and the second gear by input of drive torque. A connecting shaft is disposed on the same axis as the first gear and is connected to the cam mechanism. A rotating body is disposed on the same axis as the second gear and is connected to the connecting shaft. When the connecting shaft is inserted into a long hole of the rotating body, the rotating body is connected to the connecting shaft in an eccentric position corresponding to the amount of eccentricity between the first gear and the second gear. The major axis of the long hole is set so as to allow the rotating body and the connecting shaft to move relative to one another along the longitudinal direction of the long hole.
