Claims

[Claims for Utility Model Registration] (1) A left axle having a left drive wheel 16a at its left end and supported so as to be rotatable so that the direction of the left drive wheel 16a can be changed to the left with respect to the vehicle traveling direction. 43a, a right side axle 43b having a right side drive wheel 16b at its right end and rotatably supported so that the direction of the right side drive wheel 16b can be changed to the right with respect to the vehicle traveling direction, and a power source extending in the left-right direction. The shaft 22 is integrally rotatably attached to the left and right ends of the power shaft 22, respectively, and when the left drive wheel 16a and the right drive wheel 16b are facing in the straight traveling direction, the left drive wheel 16a and the right drive wheel The power shaft 22 due to frictional contact with the
a left friction body 44 that transmits the rotational power of to the left drive wheel 16a and the right drive wheel 16b, respectively;
a, the right friction body 44b, and the left drive wheel 16
the left axle 43a and the right axle 43b so that the right drive wheel 16b and the right drive wheel 16b face straight ahead.
A drive unit structure for a self-propelled vehicle, characterized in that it has a biasing member 58 that biases the. (2) The left friction body 44a and the right friction body 44b are located on the inner peripheral side of the left drive wheel 16a and the right drive wheel 16b, respectively, and are located inside the left drive wheel 16a and the right drive wheel 16b. Claim 1 characterized in that frictional contact is possible with the periphery.
The self-propelled vehicle listed.
