Claim 8

A four-wheel-drive motor vehicle of transversely-disposed engine type as defined in claim 5, wherein the directional change gear comprises a bevel gear which meshes with another bevel gear provided at a forward end of a propeller shift.

Claim 9

A four-wheel drive motor vehicle of transversely disposed engine type as defined in claim 2, further comprising an exhaust pipe of said engine extending from a front side of said front axle to a rear side of the vehicle body below said front axle, and an oil pan expanded downward and mounted below said engine, said exhaust pipe being arranged at a position to pass below said front axle between said oil pan and said center differential.

Claim 10

A four-wheel drive motor vehicle of transversely disposed engine type as defined in claim 2, wherein said engine is a V-type engine having a pair of banks in front and in rear, said front bank and said rear bank are connected with a front exhaust pipe and a rear exhaust pipe respectively through the medium of an exhaust manifold and said front exhaust pipe extends in a rear direction of the vehicle body, passing below the front axle between an oil pan and said center differential, from in front of the front axle and is combined with said rear exhaust pipe at a rear position of the axle.

Claim 11

A four-wheel drive motor vehicle of transversely-disposed engine type, in which an output shaft of the engine extends in the direction of vehicle width, the motor vehicle comprising: a front axle extending in the direction of vehicle width for transferring engine output to front wheels, the front axle positioned forward of horizontally adjacent portions of the engine, front differential gears disposed on the front axle, a directional change gear for transmitting driving force to rear wheels through a propeller shaft, the front differential gears and the directional change gear being disposed on the front axle and spaced a predetermined distance in the direction of vehicle width from one another, housing means for enclosing the front differential gears and the directional change gear, the housing means having a narrow portion so as to form a space below the front axle between the housing means and ground, a steering mechanism disposed in front of the front axle and extending in the direction of vehicle width, and a steering shaft for transferring steering operation by a vehicle driver to the steering mechanism, the steering shaft extending in the longitudinal direction of vehicle body below the engine and passing through said space formed by the housing means.

Claim 12

A four-wheel drive motor vehicle of transversely-disposed engine type, in which an output shaft of the engine extends in the direction of vehicle width, the motor vehicle comprising: a front axle extending in the direction of vehicle width for transferring engine output to front wheels, the front axle positioned forward of horizontally adjacent portions of the engine, front differential gears disposed on the front axle, a directional change gear for transmitting driving force to rear wheels through a propeller shaft, the front differential gears and the directional change gear being disposed on the front axle and spaced a predetermined distance in the direction of vehicle width from one another, housing means for enclosing the front differential gears and the directional change gear, the housing means having a narrow portion so as to form a space below the front axle between the housing means and ground, a steering mechanism disposed in front of the front axle and extending in the direction of vehicle width, and a steering shaft for transferring steering operation by a vehicle driver to the steering mechanism, the steering shaft extending in the longitudinal direction of vehicle body below the engine and passing through said space formed by the housing means.

Claim 13

A four-wheel drive motor vehicle of transversely-disposed engine type as defined in claim 10 further comprising an exhaust pipe of said engine extending from a front side of said front axle to a rear side of the vehicle body below said front axle, and an oil pan expanded downward and mounted below said engine, said exhaust pipe being arranged at a position to pass below said front axle between said oil pan and said housing means.

Claim 14

A four-wheel drive motor vehicle of transversely-disposed engine type as defined in claim 10, wherein said engine is a V-type engine having a pair of banks in front and in rear, said front bank and said rear bank are connected with a front exhaust pipe and rear exhaust pipe respectively through the medium of an exhaust manifold and said front exhaust pipe extends in a rear direction of the vehicle body, passing below the front axle, from in front of the front axle and is combined with said rear exhaust pipe at a rear position of the axle.
