ABSTRACT:
A motor driven toy including a transmission mechanism having two output gears each engageable directly with a high speed transmission gear and a low speed transmission gear. One of the output gears is engaged with the high-speed transmission gear for the high-speed low-torque operation, whereas the other output gear is engaged with the low-speed transmission gear for low-speed high-torque operation. The change-over therebetween is well conducted by a tire load transmission cam having a synchronizing gear and a clutch mechanism provided between the synchronizing gear and the other output gear.
