Abstract
The invention provides a novel toy vehicle comprising a body, a chassis at least having an upper surface and a rolling oscillation generating unit provided on the upper surface of the chassis for permitting the body to exhibit a rolling oscillation motion around a horizontal axis. The rolling oscillation generating unit comprises a plate mounted to an internal surface of the body, a plurality of connection rods for mechanically and movably connecting the plate to the upper surface of the chassis, and at least a pushing up member mechanically connected to the chassis and having at least two contacting portions for contacting on a flat bottom surface of the plate at least at its two symmetrical positions spaced along a vertical direction to the horizontal axis so as to permit either of the two contacting portions to pushing up the bottom surface of the plate. The two contacting portions alternatively and continuously push up the bottom surface of the movable plate to permit both the movable plate and the body to show a rolling oscillation motion around the horizontal axis.
