Toy vehicle
摘要:
A toy vehicle has a propeller driven by an elastic band motor for propelling it along the ground. The vehicle has a front wheel located ahead of the remaining parts of the vehicle and pivoted to the vehicle and connected to the band so that when the wheel strikes an obstacle it resiliently yields by extending the band to absorb shock.
