TOY VEHICLE

摘要

A toy vehicle (10) includes a plurality of wheels (40), and an electric motor (52) operably coupled to rotate at least one of the wheels (40a, 40c). The one wheel (40a, 40c) including a hub (42) and a tire (44) mounted on the hub, the tire having an interior (44a) sufficiently hollow to make the wheel buoyant in water and the wheel being sufficiently sealed to prevent water penetration of the interior of the tire with the wheel immersed in water. The tire has a central portion (45) surrounding the hub and a plurality of hollow lobes (46) spaced from one another about the central portion. Each lobe has a pair of opposing outer sides (46a, 46b) at least one outer side being at least partially cupped (48a, 48b) to improve thrust caused by rotation of the wheel in water.
