<p>This gear transmission device is provided with a case, a carrier, a crankshaft, and two external gears. An internal gear is formed at the inner periphery of the case. The carrier is supported at the case coaxially with the internal gear. The crankshaft is supported at the carrier, and has two eccentric bodies. The two external gears respectively engage the two eccentric bodies. The two external gears rotate eccentrically while being meshed with the internal gear. A disk having a regulated position in the axial direction is provided to the crankshaft. The disk is sandwiched by the two external gears, and so the movement in the axial direction of the crankshaft is regulated.</p> |
