An amphibious vehicle has a body with front and rear portions, opposite sides and a bottom. The vehicle includes at least one pair of wheels, each wheel being located adjacent a respective side, and a wheel mounting structure for moving the respective wheel between raised and lowered positions thereof. Thus, when the wheels are in the raised position, lower portions of the wheels are raised above the bottom, providing clearance when the vehicle is used in water, and when in the lowered position thereof, the lower portions of the wheels are below the bottom to support the vehicle on a bearing surface. Preferably, the vehicle has two pairs of wheels, and each pair can be moved independently of the remaining pair. For some uses, the wheels of each pair could be moved independently of each other.

An amphibious vehicle comprising: (a) a body having front and rear portions, opposite sides and a bottom, the bottom curving smoothly upwardly at the front and rear portions of the body; (b) at least one pair of wheels, each wheel being located adjacent a respective side; (c) at least one pair of wheel mounting means for moving the respective wheel between raised and lowered positions thereof, so that when in the raised position thereof, lower portions of the wheels are raised above the said bottom, and when in the lowered position thereof, the lower portions of the wheels are below the said bottom, each wheel mounting means including: each side of the body having a guide means for guiding the wheel, each guide means comprising a recess within the respective side of the body, each recess being defined in part by oppositely facing, generally U-sectioned guide walls, each guide wall having a transversely disposed central wall, and a pair of oppositely facing longitudinal side walls, clearance being provided between the side walls adjacent an outside of the body, a support means for mounting the wheel for rotation relative thereto, the support means cooperating with the guide means for moving therealong between raised and lowered positions of the wheel, the support means comprising a carriage fitted within the recess, and a wheel journalling means cooperating with the carriage to permit rotation of the wheel relative to the carriage, each carriage comprising a pair of two bearing members having an outer shape generally complementary to the respective U-sectioned guide wall, the said wheel journalling means extending from the carriage through the clearance between the side walls, actuating means for moving the carriage along the guide means between the raised and lowered positions, the actuating means cooperating with the body and the carriage; and (d) the bottom of the vehicle has a low friction, wear-resisting plastic composition extending between the sides of the body and between upper portions of the bottom.
