Patent ID: 7637831

Claim:
A power transmission mechanism for use in a model vehicle, comprising: a drive unit for traveling providing a drive force for traveling to said model vehicle; a first rotating shaft to which the drive force of said drive unit for traveling is transmitted; a first differential gear and a second differential gear to which the rotation of said first rotating shaft is transmitted; a first wheel rotated by said first differential gear; a second wheel rotated by said second differential gear; a drive unit for turning providing a drive force for turning to said model vehicle; a second rotating shaft to which the drive force of said drive unit for turning is transmitted; a third differential gear to which the rotation of said second rotating shaft is transmitted; a third rotating shaft transmitting the rotation transmitted from said third differential gear to said first differential gear; and a control part controlling the rotations of said drive unit for traveling and said drive unit for turning; wherein said third differential gear transmits the rotation transmitted from said second rotating shaft to said third rotating shaft through differential rotation, and said first differential gear transmits the rotation transmitted from said third rotating shaft to said first wheel through differential rotation, and wherein said second rotating shaft transmits the rotation transmitted from said drive unit for turning to said second differential gear, and said second differential gear transmits the rotation transmitted from said second rotating shaft to said second wheel through differential rotation.
